  • Drunk Elephant Protini: The Peptides Start at Ingredient #10

    Drunk Elephant Protini is sold as a “polypeptide” firming moisturizer with a nine-peptide complex. On the label, the first peptide — sh-Oligopeptide-1 — appears at ingredient number ten, after water, an emollient, glycerin, three emulsifiers, a seed oil, a ferment and a botanical extract. The copper compound in the formula is Copper Palmitoyl Heptapeptide-14, which is not the same molecule as copper tripeptide-1 (GHK-Cu), the copper peptide most of the published research is actually about.

    We quote ingredient lists so you can check them yourself. Here is Protini’s, verbatim from the Drunk Elephant product page (drunkelephant.com, fetched 13 October 2026, HTTP 200), and corroborated word-for-word by a major US retailer’s listing for the same product (SKU P427421). Ingredient Desk is published by the team behind Evil Goods, who make a copper peptide serum of their own; we say so here, in the footer, and anywhere an Evil Goods product comes up.

    What is actually in Drunk Elephant Protini?

    The front of the jar leads with peptides. The first nine ingredients are not peptides. In descending order of how much is in the jar, they are:

    1. Water — the solvent almost every water-based cream is built on.
    2. Dicaprylyl Carbonate — a light emollient ester, the kind of silicone alternative that gives a cream its slip.
    3. Glycerin — a humectant, one of the most reliable and least expensive moisturizing agents there is.
    4. Cetearyl Alcohol — a fatty alcohol that thickens and helps emulsify.
    5. Cetearyl Olivate and Sorbitan Olivate (5 and 6) — a pair of olive-derived emulsifiers that hold oil and water together.
    6. Sclerocarya Birrea Seed Oil — marula oil, a genuinely nice emollient with antioxidants.
    7. Bacillus/Folic Acid Ferment Extract — a fermented folic acid ingredient Drunk Elephant markets as a hero.
    8. Nymphaea Alba Root Extract — pygmy waterlily extract, the brand’s “stem cell” botanical.

    None of this is a criticism. It is a perfectly competent moisturizer base — marula oil and a folic-acid ferment are more interesting than most. The point is only that these eight ingredients, not the peptides, make up the bulk of what you are applying. That is what “descending order of predominance” means, and it is worth knowing before we get to the part the name is selling.

    Nib, a small round pencil-sketch creature, holds a magnifying glass up to a tall jar labelled Polypeptide, squinting at the fine print on the back.
    Nib reads the back of the jar, not the front. The front says polypeptide; the back has fifty-eight lines to get through first.

    Where do the peptides actually appear?

    US cosmetic labels have to list ingredients in descending order of how much is present, down to one percent. Below one percent, a brand can list things in any order it likes. That rule is set out in 21 CFR 701.3 — subsection (a) requires descending order; subsection (f)(2) is the under-one-percent exemption. So ingredient position is not an exact percentage, but above that one-percent line it is a real signal of how much is in the jar.

    Here is where Protini’s nine peptides sit:

    Position INCI name What it is
    10 sh-Oligopeptide-1 growth-factor-type peptide (EGF-style) — the first peptide in the list
    11 sh-Oligopeptide-2 growth-factor-type peptide (IGF-1-style)
    12 sh-Polypeptide-1 growth-factor-type peptide (bFGF-style)
    13 sh-Polypeptide-9 growth-factor-type peptide
    14 sh-Polypeptide-11 growth-factor-type peptide
    15 Copper Palmitoyl Heptapeptide-14 the copper peptide — a seven-amino-acid chain with a fatty-acid tail and copper
    16 Heptapeptide-15 Palmitate signal peptide
    17 Palmitoyl Tetrapeptide-7 signal peptide (often sold as Rigin)
    18 Palmitoyl Tripeptide-1 signal peptide — a palmitoylated GHK chain, without the copper

    The peptides occupy positions ten through eighteen. The one directly after them, at nineteen, is alanine — an individual amino acid. On most labels, the appearance of free amino acids marks the point where you have crossed below the one-percent line. The whole nine-peptide complex, in other words, almost certainly lives in the slice of the formula that sits under one percent combined. That is normal for peptides; they work at low concentrations. It is simply not what “polypeptide cream” implies to someone reading the front.

    Nib stands at the foot of a long numbered ladder of ingredients, pencil pointing up at rung number ten where the first peptide sits.
    The first peptide waits nine rungs up the list. Everything below it is the moisturizer most moisturizers already are.

    Is the copper peptide in Protini the one the research is about?

    At position fifteen is Copper Palmitoyl Heptapeptide-14. When most people say “copper peptide” they mean something else: copper tripeptide-1, also written GHK-Cu (CAS 89030-95-5), a three-amino-acid chain bound to copper. GHK-Cu is the compound with the long history — a 2025 review of tripeptides in skin calls it one of the most-used peptides in the cosmetic industry and names copper tripeptide-1 as its INCI identity. Protini does not contain copper tripeptide-1. It contains a different, palmitoylated copper peptide.

    That difference matters for how you read the research. A 2026 systematic review of GHK-Cu describes forty-plus years of pre-clinical work, then adds the honest part: the clinical evidence “remains thin and fragmented,” most trials are small, and the findings have not been validated in large human studies. So even for the best-studied copper peptide, the human evidence is promising rather than settled. For Copper Palmitoyl Heptapeptide-14 specifically, the published literature is thinner still — which is not the same as saying it does nothing, only that you should not read GHK-Cu’s forty-year file as if it belonged to this molecule. If you want the plain-English version of what a copper peptide even is, we wrote one (that is our site, Evil Goods).

    Nib holds up two labelled test tubes side by side, one marked Copper Tripeptide-1 and one marked Copper Palmitoyl Heptapeptide-14, looking from one to the other.
    Two copper peptides, two different names. Nib checks which one the research is actually about.

    What is everything below position eighteen?

    The back half of the list is mostly supporting cast. Positions nineteen through twenty-nine are individual amino acids — alanine, arginine, glycine and the rest — which act as natural moisturizing factors and as the building blocks peptides are made from, but are not themselves peptides. Sodium hyaluronate, the much-hyped hydrating ingredient, sits all the way down at position thirty-two, well below that one-percent line.

    Two preservatives sit near the very bottom: chlorphenesin at position fifty-two and phenoxyethanol at fifty-three. The Cosmetic Ingredient Review panel concluded chlorphenesin is safe at present practices of use and concentration. Alongside that, the patch-test literature carries a handful of case reports of allergic contact dermatitis from products containing it — the CIR report itself cites several. These are rare reactions at low rates, not a reason to avoid the ingredient, but worth knowing if your skin has flagged a preservative before. That is the honest shape of it: broadly safe by the review body’s assessment, with a small sensitization signal in the case reports.

    Nib sits cross-legged at the bottom of the ingredient list reading a tiny footnote next to the word Chlorphenesin, a stack of case-report papers beside him.
    Down at position fifty-two, Nib stops to read the footnotes a few people have left on the preservative.

    So is Drunk Elephant Protini worth it?

    If you like how it feels and it suits your skin, the position of an ingredient does not undo that — a good emollient base is a real thing to buy. What the label does tell you is that you are paying a peptide-cream price for a cream whose peptides sit below one percent, built on a base you could find in far cheaper moisturizers. Whether that trade is worth it is a judgement about your own skin and budget, not something the front of the jar settles for you. If you specifically want copper peptides, it is worth knowing which copper peptide you are buying and how thin the human evidence still is for any of them — including the one in our own Copper Peptide Blue Honey Serum, which uses copper tripeptide-1.

    FAQ

    Where do the peptides start in Drunk Elephant Protini?
    At ingredient number ten, sh-Oligopeptide-1. The first nine ingredients are water, an emollient ester, glycerin, three emulsifiers, marula seed oil, a folic-acid ferment and a waterlily extract.
    What is sh-Oligopeptide-1?
    A synthetic growth-factor-style peptide (an EGF analog) used in skincare at low concentrations. It is the first of Protini’s nine-peptide complex.
    Is the copper peptide in Protini GHK-Cu?
    No. Protini contains Copper Palmitoyl Heptapeptide-14. GHK-Cu is copper tripeptide-1, a different molecule and the one most of the published research is conducted on.
    What does ingredient order tell you about a moisturizer?
    US rules require listing in descending order of amount down to one percent (21 CFR 701.3). So an ingredient’s position is a real signal of how much is present — above the one-percent line, at least. Below it, order no longer reflects quantity.
    Is chlorphenesin safe?
    The Cosmetic Ingredient Review panel concluded it is safe at the concentrations cosmetics use. A small number of allergic contact dermatitis case reports exist in the patch-test literature, which is a sensitization note rather than a general warning.
    Nib closes a thick notebook, magnifying glass tucked under one arm, giving a small satisfied nod next to the finished ingredient list.
    The label told the whole story. It just told it in order of how much is in the jar.
  • Drunk Elephant Protini: The 9 Peptides Are #10–18. Then Come 10 Amino Acids.

    Drunk Elephant Protini is named for polypeptides and
    marketed on “nine signal peptides.” On the ingredient list, those nine
    peptides sit together at positions #10 through #18 — genuinely mid-list, not
    buried at the bottom. The catch is not where they sit. It is what comes right
    after them: ten individual amino acids at positions #19 through #28, which the
    brand groups under the same peptide-complex language. An amino acid is not a
    peptide; it is what a peptide is made of. Those are different things.

    Most of the labels we read here end with the marketed hero hiding somewhere
    below the preservatives — retinol at #26, hyaluronic acid at #25. Protini is
    the opposite case, and that is exactly what makes it interesting. Drunk Elephant
    put its nine peptides where you would hope to find them, in one tidy block near
    the top of the list. So the usual gotcha does not apply. The interesting
    questions are different: what are those nine peptides, does the research support
    what they are named for, and what is that long run of ingredients that follows?

    Nib, a small round pencil-sketch creature, holds a magnifying glass to a jar of moisturizer whose front reads Polypeptide, then peers past it at a long ingredient list running down the side.
    Named for polypeptides. Nib turns the jar around to find where the nine actually live.

    Where do the nine signal peptides actually sit?

    Here is the full list, quoted verbatim as it appears on the product page at
    Ulta.com,
    fetched 16 September 2026 (item #2588434). The list on the product’s page at
    a second major beauty retailer, read the same week, is identical word for word,
    down to the spacing.

    Water/Aqua/Eau, Dicaprylyl Carbonate, Glycerin, Cetearyl Alcohol, Cetearyl Olivate, Sorbitan Olivate, Sclerocarya Birrea Seed Oil, Bacillus/ Folic Acid Ferment Filtrate Extract, Nymphaea Alba Root Extract, sh-Oligopeptide-1, sh-Oligopeptide-2, sh-Polypeptide-1, sh-Polypeptide-9, sh-Polypeptide-11, Copper Palmitoyl Heptapeptide-14, Heptapeptide-15 Palmitate, Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1, Alanine, Arginine, Glycine, Histidine, Isoleucine, Phenylalanine, Proline, Serine, Threonine, Valine, Acetyl Glutamine, Coconut Alkanes, Coco-Caprylate/Caprate, Sodium Hyaluronate, Aspartic Acid, Linoleic Acid, Linolenic Acid, Lecithin, Butylene Glycol, Polyvinyl Alcohol, Sodium Lactate, Sodium PCA, PCA, Sorbitan Isostearate, Carbomer, Polysorbate 20, Polysorbate 60, Lactic Acid/Glycolic Acid Copolymer, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Xanthan Gum, Isomalt, 1,2-Hexanediol, Caprylyl Glycol, Chlorphenesin, Phenoxyethanol, Tocopherol, Sodium Benzoate, Phenylpropanol, Glyceryl Caprylate, Symphytum Officinale Callus Culture Extract.

    The nine peptides the product is named after run from
    sh-Oligopeptide-1 at position #10 to
    Palmitoyl Tripeptide-1 at position #18 — nine names in an
    unbroken block. Above them are eight ingredients that are none of them a peptide:
    water, an emollient ester, glycerin, two fatty-alcohol emulsifiers, a pair of
    olive-derived emulsifiers, marula oil, and two ferment extracts. On an ingredient
    list, where things are ordered roughly by weight down to about the 1% mark, that
    puts the peptide block mid-list rather than at the top. Not hidden, not headline.
    Somewhere in the honest middle.

    Nine “signal peptides”

    So this is not a “the hero is at #26” story. Credit where it is
    due: the peptides are real and reasonably placed. The story is what they are, and
    whether the research backs the word on the front of the jar.

    Nib runs a pencil down a numbered column and rests it on a tight block of nine little peptide tags clustered together between positions ten and eighteen.
    The nine signal peptides sit together at positions ten through eighteen – mid-list, not buried.

    Do the peptides do what the name promises?

    Five of the nine — the sh-Oligopeptide and sh-Polypeptide entries at
    positions #10 through #14 — are cosmetic-grade analogs of growth factors.
    sh-Oligopeptide-1, at #10, is the INCI name for a synthetic epidermal growth
    factor analog. This is where the evidence gets thin, and it is worth being
    precise about how thin.

    A 2023 review in Cutaneous and Ocular Toxicology looked specifically
    at topical sh-oligopeptide-1 and concluded that its preclinical bioactivity as a
    functional growth factor has not been demonstrated, meaning clinical trials that
    treat it as equivalent to functional recombinant growth factor may not rest on a
    valid foundation (Martínez-Carpio,
    2023, PubMed
    ). That is an evidence-quality critique, not a safety alarm: the
    question is whether the molecule does the job it is named for, not whether it is
    harmful.

    Zoom out to the whole category and the picture is consistent. A systematic
    review of topical growth-factor preparations — 33 studies, nine randomized
    controlled trials, 1,180 participants — found modest improvements in
    texture and fine lines versus baseline, with three of the comparative RCTs showing
    no statistically significant difference between treatments, and the studies
    limited by heterogeneity and weak placebo controls
    (Quinlan et al.,
    Journal of Cosmetic Dermatology, 2023, PubMed
    ). Modest and inconsistent is
    the honest reading — not dismissal, not endorsement.

    The last two of the nine are a different, better story. Palmitoyl Tetrapeptide-7
    and Palmitoyl Tripeptide-1, at #17 and #18, are the two peptides marketed together
    as Matrixyl 3000. A 45-person randomized, placebo-controlled study reported around
    52% wrinkle reduction over twelve weeks — better evidence than the growth
    factor peptides above them, though the trial was manufacturer-commissioned and the
    two peptides are always tested as a pair, so the data cannot separate them
    (peptidings.com,
    2026
    ). So within the nine, the picture is mixed: the two at the bottom of the
    block have the most credible support, and the five growth-factor analogs above
    them the least.

    What is that long run of ingredients after the peptides?

    This is the part of the label worth reading slowly. Directly below the nine
    peptides, positions #19 through #28 are ten individual amino acids in a row:
    alanine, arginine, glycine, histidine, isoleucine, phenylalanine, proline, serine,
    threonine and valine, with acetyl glutamine at #29. Drunk Elephant groups these
    under the same “Signal Peptide Complex” language it uses for the
    peptides — but they are not peptides.

    Nib stands beside a neat row of ten identical amino-acid blocks, counting them on stubby fingers, with a small sign above the row reading not peptides.
    Then ten single amino acids in a row. An amino acid is what a peptide is made of, not a peptide.

    The distinction matters and it is not pedantry. A peptide is two or more amino
    acids joined by a peptide bond; that bond is what lets it act as a signal. A free
    amino acid on its own is the raw material, not the assembled thing. The ten listed
    here are among the cheapest commodity inputs in a cosmetic chemist’s cabinet,
    and they do a real, modest job as surface humectants — they are Natural
    Moisturizing Factor components, the same molecules your skin already uses to hold
    water. That is fine. What is worth noticing is the effect on the label: the
    peptide-and-amino-acid run stretches from position #10 all the way to #29, twenty
    consecutive entries, which reads as a peptide powerhouse when read for length.
    Ten of those twenty are single amino acids.

    Label positions What sits there What the position implies
    1–9 Water, emollients, emulsifiers, marula oil, two ferments The base and texture — none of them a peptide
    10–14 Five growth-factor analogs (sh-Oligo/Polypeptides) Real peptides, mid-list; cosmetic bioactivity contested
    15–16 Copper Palmitoyl Heptapeptide-14, Heptapeptide-15 Palmitate Copper peptide plus a palmitoylated heptapeptide
    17–18 Palmitoyl Tetrapeptide-7, Palmitoyl Tripeptide-1 Matrixyl 3000 pair — best-studied of the nine
    19–29 Ten amino acids + acetyl glutamine Cheap humectants; not peptides
    32 Sodium Hyaluronate Below the whole peptide/amino-acid block

    To be fair to the formula: none of this is deceptive on the label itself. The
    list is honest and complete. It is the marketing language wrapped around it —
    counting ten amino acids toward the impression of a peptide complex — that a
    slow read pulls apart.

    Nib holds up two copper coins side by side - one large and dented and labelled old, one small and shiny and labelled new - comparing them through the magnifying glass.
    Two different copper peptides. The one here is the newer, less-studied cousin of the classic GHK-Cu.

    Is the copper peptide in here the one with the research behind it?

    At position #15 is Copper Palmitoyl Heptapeptide-14 — a copper-bearing
    peptide. It is easy to assume this is the copper peptide with the long research
    record. It is not. The copper peptide that has been studied since the 1970s is
    Copper Tripeptide-1, better known as GHK-Cu. Copper Palmitoyl Heptapeptide-14 is a
    newer, oil-soluble variant marketed on superior delivery, but with a much shorter
    research history. GHK-Cu has been studied since the 1970s across many independent
    papers; Copper Palmitoyl Heptapeptide-14 is the payload peptide in a newer
    encapsulated delivery system (trade-named X50), and the evidence cited for it is a
    single 30-person, 28-day manufacturer in-vivo test rather than a body of
    independent work (INCIDecoder,
    Copper Palmitoyl Heptapeptide-14
    ). Neither is a bad ingredient. They are just
    not the same molecule, and the older one is the one with the deeper record.

    That contrast is worth flagging because we make a copper peptide product and it
    uses the other one. Evil Goods’
    Copper
    Peptide Blue Honey Cream (our product)
    is built on Copper Tripeptide-1
    — the GHK-Cu with the longer research record — alongside Manuka honey,
    niacinamide and olive squalane. It is the same product format, a cream rather than
    a serum, which makes it the fair thing to compare against here. In the interest of
    the same scrutiny we just applied to Protini: Evil Goods does not publish a copper
    concentration for ours, so we cannot tell you how much is in there any more than
    Drunk Elephant can tell you about its nine peptides. Ingredient Desk is published
    by the team behind Evil Goods, so read our comparisons knowing that.

    What about the clinical study on the box, and the last ingredient?

    Drunk Elephant’s marketing cites a study: 31 people, eight weeks, with
    high percentages reporting improvement in tone, texture and hydration. A couple of
    points are worth knowing before you weigh those numbers. It does not appear to be
    peer-reviewed — no published paper turns up — and at 31 participants
    with no control arm described, it is the kind of small brand-commissioned consumer
    panel that is prone to the assessment bias these trials are known for. That does
    not make it invalid; it simply cannot be verified, so treat the figures as
    in-house marketing data rather than independent evidence.

    One last note for the completists. The final ingredient on the list is Symphytum
    Officinale Callus Culture Extract — comfrey, but specifically the plant-cell
    callus culture form, which is produced to minimize the pyrrolizidine alkaloids
    that are the usual concern with comfrey root and leaf. At the very bottom of a
    long list, present in trace amount, in the callus form: there is nothing
    here to raise an eyebrow at. We mention it only because a reader scanning the
    label for “comfrey” deserves to know which comfrey it is.

    So is it worth it?

    On its own terms, Protini is a more honest label than most we read. The nine
    peptides are real and mid-list, not buried. Two of them are genuinely
    well-supported. The open questions are the five growth-factor analogs, whose
    cosmetic activity the research does not yet back; the ten amino acids counted
    toward the peptide story that are not peptides; and a copper peptide that is the
    newer, less-studied cousin of the classic one. If you like the texture and go in
    understanding that “nine signal peptides” is a mixed bag rather than
    nine proven actives, it is a defensible cream at its price. Just read it as what
    the label says, not what the front of the jar implies.

    FAQ

    Where do the peptides sit in Drunk Elephant Protini?
    The nine marketed signal peptides run from position #10 to #18 in one block,
    below eight ingredients that are not peptides. That is mid-list — not buried,
    but not the top of the label either.

    Are the amino acids in Protini the same as the peptides?
    No. Positions #19 through #28 are ten individual amino acids. An amino acid is a
    single building block; a peptide is two or more of them bonded together. Free
    amino acids are cheap humectants, not the signal peptides the product is named
    for.

    Does Protini have the copper peptide with the most research?
    Not the classic one. It contains Copper Palmitoyl Heptapeptide-14 at #15, a newer
    oil-soluble variant, rather than Copper Tripeptide-1 (GHK-Cu), which has the
    longer, decades-deep research record.

    Is the clinical study on Protini reliable?
    It is a 31-person, eight-week brand-commissioned panel with no control arm
    described and no peer-reviewed publication found. Treat the percentages as
    in-house marketing data rather than independent evidence.

    Do topical growth-factor peptides actually work?
    A systematic review of the category found modest, inconsistent improvements in
    texture and fine lines, with weak placebo controls across studies. For the
    cosmetic-grade EGF analog specifically, a 2023 review concluded its functional
    bioactivity has not been demonstrated.

    Nib closes a small notebook titled Ingredient Desk, sets the magnifying glass down beside the fully-read jar, and gives a satisfied nod.
    Label read, top to bottom. The peptides are real and mid-list. What is unproven is what each one does.
