These days, it seems I cannot escape peptides. Online, I\u2019ve been assaulted by videos of shirtless Chads injecting dubiously sourced bottles of the so-called \u201cWolverine stack<\/a>.\u201d On the New York City subway, I\u2019m haunted by Serena Williams\u2019 Ro ads for easy GLP-1 access. Silicon Valley seems to be a parade of peptide parties<\/a>. In Washington, RFK Jr. has said he\u2019s pro-peptide<\/a> and wants to expand access. In July, the FDA will meet to possibly reclassify 14 peptides<\/a> so they can be eligible for compounding.<\/p>\n<\/div>\n

\n

And in Hollywood, Gwyneth Paltrow \u2014 mother Goop, one of the original wellness influencers \u2014 is selling a series of peptide skincare products. Except, after some research, I\u2019m not sure Paltrow actually understands what peptides are.<\/p>\n<\/div>\n

\n

You might be wondering why I\u2019m fixating on a Goop product in Optimizer<\/em>. The short answer: While researching peptides for a forthcoming feature, I\u2019ve descended into madness.<\/p>\n<\/div>\n

\n

The longer answer is that peptide mania is central to Silicon Valley\u2019s current fixation with longevity and metabolic optimization. As I\u2019ve recently written<\/a>, wellness trends increasingly inform new health tech features and gadgets that make up the wearable surveillance state<\/a>. Peptides are also being framed on social media as an innovation that democratizes healthcare. (A similar rhetoric used to describe wearables!) It\u2019s part of the wellness Wild West feedback loop that\u2019s fueling Silicon Valley\u2019s obsession with self-optimization. With that in mind, it\u2019s worth examining how \u201cpeptide washing\u201d has crept into various corners of the internet \u2014 and the resulting ripple effects.<\/p>\n<\/div>\n

\n

While peptide shots are a relatively new trend, we\u2019ve known about peptides and how they work for decades. They\u2019re short chains of amino acids, which, in turn, make up proteins. In other words, building blocks for the building blocks. Because a peptide can be a chain ranging from two to roughly 100<\/a> amino acids, there are potentially trillions<\/em> of peptides<\/a>. Their main function is to act as messengers for various bodily functions. Some are naturally occurring and often come from the foods you eat. Others are made synthetically in a lab. The most famous ones include insulin and GLP-1 medications like semaglutide (Ozempic and Wegovy) and tirzepatide (Zepbound and Mounjaro).<\/p>\n<\/div>\n

\n

What\u2019s taking social media by storm are peptides that exist in legal gray areas. They\u2019re not widely tested or FDA-approved drugs, and are sometimes sourced from dubious suppliers<\/a>. I\u2019ve previously written about retatrutide \u2014 another popular weight loss peptide \u2014 in Optimizer<\/em><\/a>, but there\u2019s a whole slew of others with names that sound vaguely like Star Wars<\/em> droids. The most popular ones include BPC-157, TB-500, GHK-Cu, and CJC1295. These peptides are touted as biohacks for ailments ranging from fat loss and muscle growth, to faster wound healing, anti-aging, and increased energy. Essentially, everything associated with living a longer, healthier life. Lumped alongside these is NAD+, which is not<\/em> a peptide but is often marketed as one. That\u2019s partly because it\u2019s frequently consumed as an IV drip and is thus an injectable substance.<\/p>\n<\/div>\n

\n

But just because you can inject something, that doesn\u2019t make it a peptide.<\/p>\n<\/div>\n

\n
\n
\n

Do you have experience using peptides?<\/h2>\n<\/p>\n<\/div>\n
\n

Or extremely strong feelings about this trend? I\u2019m researching this phenomenon and I\u2019d love to chat with you. Hit me up at victoria.song@theverge.com or on Signal at @ vicmsong.14.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

NAD stands for nicotinamide adenine dinucleotide<\/a>. It\u2019s a coenzyme \u2014 basically an enzyme booster \u2014 that\u2019s found in every cell. Its primary job is to help convert food into energy. It does this by shuttling electrons from one chemical reaction to another. As you age, your NAD levels naturally decline. This can lead to an array of conditions associated with aging, like Type 2 diabetes, lower energy levels, and saggy skin. Not to get too weedsy, but the + in NAD+ simply denotes one of two versions of the NAD molecule. (The other is NADH.)<\/p>\n<\/div>\n

\n

Which, finally<\/em>, brings me to the Goop Youth Boost NAD+ Peptide Rich Cream<\/a> and whether Gwyneth Paltrow actually knows what a peptide is.<\/p>\n<\/div>\n

\n

In my research, I was looking into influential people who have spoken out about peptide injections. There\u2019s a long list, but in Hollywood, Paltrow\u2019s name kept popping up. Cue this recent Elle <\/em>interview<\/a>, in which Paltrow plays a \u201cfuck, marry, kill\u201d game with wellness trends.<\/p>\n<\/div>\n

\n

From the get-go, the Elle<\/em> article incorrectly identifies NAD+ as a peptide. Paltrow is then quoted as saying she uses NAD+ IV drips and an injectable NAD+ pen for impromptu energy boosts. She goes on to say that injectable peptides dealing with inflammation and brain health that are \u201cbeing formulated for longevity\u201d will be the next NAD+. In the fuck, marry, kill game, Paltrow is asked to choose between NAD+, B12, and peptide shots. She refuses, saying she\u2019d marry them all.<\/p>\n<\/div>\n

\n
\n

\n
<\/a><\/div>\n<\/div>\n<\/div>\n

Note that the single actual peptide in this ingredient list is last. Meanwhile NMN isn\u2019t actually NAD+.<\/em><\/figcaption>Screenshot: Goop<\/cite><\/p>\n<\/div>\n<\/div>\n<\/div>\n
\n

What\u2019s worrisome is the conflation of these treatments, even though they\u2019re three separate things. It\u2019s easy for the average person to read this article and think, \u201cNAD+ is a type of peptide shot and a rich, glamorous celebrity like Gwyneth Paltrow does it, so this must be their secret to looking good.\u201d<\/p>\n<\/div>\n

\n

(For the curious: B12 is a vitamin. Supplementation can<\/em> boost energy if you have a B12 deficiency, which is relatively common in the elderly, vegetarian, and vegan populations. As for NAD+, there\u2019s considerable research interest, but limited clinical evidence for drips or supplements at the moment<\/a>. I wrote a whole Optimizer<\/em> newsletter about dubious peptide shots<\/a>.)<\/p>\n<\/div>\n

\n

From this interview, I get the sense that Paltrow knows that peptides are trendy, but she doesn\u2019t actually admit to using any specific one. After some more digging, I found she has<\/em> stated that she loves glutathione IV drips<\/a>. Now, that<\/em> is a peptide. However, she characterized her usage as \u201cI love IV drips!\u201d<\/a> so, again, I\u2019m not sure if Paltrow is aware that IV drips and peptides are not the same thing. Upon looking into her \u201cpeptide-rich\u201d moisturizer, I\u2019m even less certain.<\/p>\n<\/div>\n

\n

Calling it a \u201cYouth Boost NAD+ Peptide Rich Cream\u201d would suggest this $105 moisturizer has both NAD+ and a bunch<\/em> of peptides. Peruse the ingredient list, and you\u2019ll find it doesn\u2019t even have NAD+. It has NMN, or nicotinamide mononucleotide, a precursor (another kind of building block) for NAD+. As for its peptide content, the marketing claims the cream features \u201cbiomimetic plant-derived peptides.\u201d Again, the list only refers to one true peptide molecule: arginine\/lysine polypeptide. (A polypeptide is a longer peptide; this one supposedly helps with wrinkles.) It also appears last. In skincare, the ingredient list is generally ordered in terms of concentration. The top three to five ingredients make up the bulk of the formula. One hack is to find the so-called \u201cone percent line\u201d<\/a>, which you can estimate from when the first preservative or fragrance appears. Given how this list is written, this is a standard moisturizer with a teeny sprinkle of a single peptide thrown in for marketing flavor. Even if there was a more potent amount, peptides are delicate molecules. Effectiveness for any topical skincare active \u2014 be it peptides or salmon sperm DNA<\/a> \u2014 depends on stable formulation, concentration, whether the molecule can penetrate the skin barrier, and packaging that prevents degradation.<\/p>\n<\/div>\n

\n

In any case, I reached out to Goop to clarify the peptide content in this cream. I have not heard back.<\/p>\n<\/div>\n

\n

The only thing I can conclude is Paltrow isn\u2019t afraid to try fringe wellness trends. (That and she loves an IV drip.) If someone handed her a peptide shot with the promise of energy and youth, I\u2019d bet she\u2019d do it. But do I think a peptide-curious person could ask her to explain the pros and cons of this trend based on her public statements? Now that\u2019s a bet I would not<\/em> take.<\/p>\n<\/div>\n

\n

I could be wrong. In which case, I find her statements and her moisturizer to be disappointing given her status and influence. Case in point, the average person likely isn\u2019t going to go through the trouble of accessing gray market peptide vials. They probably won\u2019t be able to afford the same quality treatments as Paltrow, either. But a so-called peptide cream from a celebrity? That\u2019s easily accessible. And in this particular case, that consumer wouldn\u2019t be getting much of the thing they purportedly want to try.<\/p>\n<\/div>\n

\n

More concerning is the flattening of any<\/em> injectable as a peptide. Paltrow showing up to a podcast with an IV drip, speaking of peptides, phospholipids, and regular vitamins in a single breath? That\u2019s confusing. It conflates relatively harmless therapies \u2014 like vitamin supplementation \u2014 with those that aren\u2019t as well-studied. And the more influential people do this, the more regular people will too.<\/p>\n<\/div>\n

\n

Peptides aren\u2019t inherently dangerous. Injections aren\u2019t evil. But the way peptide mania has made a more extreme, experimental trend as casual as taking a multivitamin? That feels like the slipperiest of slopes.<\/p>\n<\/div>\n
