That\u2019s the carrot dangling in front of everyday athletes as a hurricane of hype for peptides sweeps through popular media.<\/p>\n
Peptides \u2014 short chains of amino acids \u2014 are everywhere right now. They\u2019re a wellness craze that\u2019s far surpassed fibermaxxing, matcha, or apple cider vinegar.<\/p>\n
Bodybuilders and biohackers are singing the praises of the notorious \u201cWolverine Stack,\u201d a peptide double-whammy of BPC-157 and TB-500 that\u2019s said to fast-track recovery and bulletproof against injury.<\/p>\n
Both superstar podcasters and rando influencers are shilling injectables that promise to plump your skin, pump your muscles, and boost your mojo.<\/p>\n
Even U.S. Health Secretary Robert F. Kennedy Jr. says he\u2019s \u201ca big fan\u201d of peptides<\/a>, which are now inching toward a regulatory reclassification that will move them out of a shady grey market and into medical prescription slips.<\/p>\n In July, the USA\u2019s Food and Drug Administration (FDA) advisory panel controversially voted<\/a> against expert advice and recommended loosening restrictions on six popular peptides.<\/p>\n It was a bombshell decision that could make these supposed wonder drugs even easier to access for those in the States. A prescription would be all it takes.<\/p>\n And for everyone else, untested, unregulated peptides are only ever a few clicks away.<\/p>\n A basic Google search and your trusted bank details are all you need to get a shipment of injectable BPC-157 and TB-500 \u2013 the two pillars of the infamous \u201cWolverine Stack\u201d \u2013 winging your way. [RIP your algorithm if you try that search out of curiosity, take it from me.]<\/p>\n Rapid recovery and injury prevention are just a course of injections away Peptides are \u2013 in theory at least \u2013 off limits for pros. The World Anti-Doping Agency (WADA) banned them in 2022.<\/p>\n But for amateurs who have no need to care about the WADA code?<\/p>\n Peptides\u2019 promise to supercharge recovery is very tempting.<\/p>\n Just imagine the gains.<\/p>\n You\u2019ll recover from VO2 Max workouts faster than Wolverine heals the rips from his claws. You\u2019ll never be injured again, no matter how hard you train. Heck, you\u2019ll be able to work so hard you\u2019ll be pushing the same power as Tadej Poga\u010dar<\/a>.<\/p>\n As a runner and rider who\u2019s suffered countless serious bone stress and tendon injuries, I get the appeal.<\/p>\n Yet these on-trend supplements might not be the medical miracle they seem.<\/p>\n They\u2019re almost entirely unproven in human clinical trials, and their long-term impacts are unknown. Scientists have theories of cancer risk. And self-injection? Let\u2019s not even look down that rabbit hole.<\/p>\n And a possible FDA approval isn\u2019t a guarantee of product quality, either.<\/p>\n Pharmacology insiders are already warning of green-lit drugs that have been incorrectly synthesized, and fear a renewed interest in peptides from dubious unsanctioned suppliers.<\/p>\n Peptides are the health and fitness trend of the moment. An FDA approval would add several million more hits to the #peptide craze.<\/p>\n Here\u2019s what cyclists should know before the hype gets out of hand.<\/p>\n What are peptides? Peptides are short chains of amino acids. Protein is also made up of amino acids, albeit in longer chains.<\/p>\n Peptides naturally occur in the body and serve multiple roles, in some cases crucial. For example, Insulin and Oxytocin are naturally occurring peptides. They\u2019re crucial to the regulation of blood sugar and childbirth, respectively.<\/p>\n Peptides are also produced synthetically for medical use.<\/p>\n Popular diabetes and weight loss drugs like Ozempic, Mounjaro, and Wegovy (also bracketed as \u201cGLP-1\u201d) are the best-known exogenous peptides.<\/p>\n Synthetic peptides like insulin and these GLP-1s treatments have been proven safe and effective, are approved by the FDA. They\u2019re prescribed by doctors all over the world.<\/p>\n But these legitimized drugs make up only a fraction of the peptides available to curious consumers.<\/p>\n BPC-157, TB-500, and the \u2018Wolverine Stack\u2019 of health superheroes There\u2019s a growing \u201cgrey market\u201d of unregulated, experimental peptides that are sold as miracles in bottles. Eternal youth and physical mastery are only a course of injections away.<\/p>\n These suppliers are unlicensed, but that\u2019s no problem \u2014 \u00a0all it takes is the label \u201cfor research purposes only\u201d to work around the legal red tape.<\/p>\n BPC-157 and TB-500 \u2014 two of the most hyped peptides of the current moment \u2014 fall within this shady \u201cexperimental\u201d category. Other on-trend experimentals include MK-677, MKV, and Ipamorelin.<\/p>\n When taken together, BPC-157 and TB-500 form the \u201cWolverine Stack\u201d that\u2019s raved about by the world\u2019s most contentious podcaster, Joe Rogan<\/a>. This peptide pair is the wellness and recovery cure of every biohacker, looksmaxxer, and gym bro on the interweb.<\/p>\n And it\u2019s easy to see the hype.<\/p>\n BPC-157 supposedly encourages healing by promoting the formation of new blood vessels. TB-500 is sold as a key signaling molecule for cellular repair.<\/p>\n That\u2019s a combination that nearly guarantees superhero status. They put recovery into fast-forward and press stop on the aging process.<\/p>\n \u201cI had tendinitis in my elbow, I started using BPC-157, and it was gone in two weeks,\u201d Rogan once said on his podcast.<\/p>\n \u201cIt is a phenomenal stack and just really helps injuries,\u201d Rogan more recently said of the Wolverine pairing.<\/p>\n Where did this peptide boom come from?<\/p>\n Rogan was one of the first noted high-profile advocates for peptides, back when they were mostly the preserve of bodybuilders and strength athletes.<\/p>\n They\u2019re now all over social media.<\/p>\n When GLP-1s began to boom in 2022, these proven diabetes and weight loss drugs dragged all sorts of stragglers with them.<\/p>\n Peptides now score daily headlines in celebrity gossip columns and \u201cmanosphere\u201d websites alike. In fact, analysts recently found<\/a> the number of new confirmed users of PBC-157 increased 33-fold between 2020 and 2026.<\/p>\n Doping bans and running controversies<\/p>\n It should be no surprise that the peptide craze has pierced world sport, too. They\u2019re a quick ticket to fast gains.<\/p>\n Dozens of pro athletes have been popped for using peptides. Triathletes, cross-fitters, and volleyball players are among the many pros currently serving sanctions.<\/p>\n The running scene in particular has been rocked by peptide scandals.<\/p>\n This spring, Cameron Hanes \u2014 a celebrated podcaster, bowhunter, and ultrarunner \u2014 provoked a heated ethics debate<\/a> when he admitted using BPC-157 as he built toward an age-group win at the Eugene marathon.<\/p>\n Likewise, former Cocodona 250 ultramarathon winner Mike McKnight is being canceled<\/a> right this very moment. He admitted using BPC-157 in the winter to avoid back surgery, and went on to win the Arizona Monster 300-miler just months later. He\u2019s been getting called out ever since.<\/p>\n<\/p>\n There are few noted cases of peptide usage in the pro peloton \u2014 they are specifically banned by WADA, after all.<\/p>\n S\u2019annara Grove was provisionally suspended<\/a> this summer after she returned an adverse analytical finding for the en-vogue Ipamorelin, but she\u2019s one of very few who\u2019s been caught out.<\/p>\n Velo heard no murmurs of peptides in the peloton after we surveyed our trusted sources.<\/p>\n It\u2019s surely a different matter in the amateur ranks.<\/p>\n For some recreational riders, peptides are as innocent as a quick fix for an injury that\u2019s been impacting their work and family life for months.<\/p>\n For the more zealous weekend warriors, the temptation to cheat in the lucrative yet largely unregulated<\/a> and untested gran fondo scene must be strong.<\/p>\n A controversial FDA vote could change everything Sporting preferences aside, Kennedy and the FDA put peptides into everybody\u2019s eyeline this month.<\/p>\n The FDA advisory panel \u2014 one reportedly influenced by RFK and criticized for its financial ties<\/a> to the peptide industry \u2014 recommended making BPC-157, TB-500, and four other popular peptides (KPV, MOTS-c, Epitalon, and Semax) available.<\/p>\n The controversy?<\/p>\n Many of the FDA\u2019s long-time staff scientists stood against the move on the grounds that there\u2019s little proof of their safety and effectiveness.<\/p>\n The evidence for BPC-157, the most popular \u201cperformance peptide,\u201d is currently limited to animal studies that found benefits for soft tissue and bone repair, organ injuries, and more.<\/p>\n There have only been three minor pilot studies on human subjects.<\/p>\n And there\u2019s no guarantee that what works on a lab rat works on a gym bunny.<\/p>\n The U.S. Anti-Doping Agency (USADA) states that \u201cbecause BPC-157 has not been extensively studied in humans, it is unknown if there is a safe dose, or if there is any way to use this substance safely to treat any specific medical conditions.\u201d<\/p>\n Quality and safety questions<\/p>\n The FDA does not have to act on the advisory panel\u2019s vote of approval for peptides. But if it does, licensed pharmacies get the green light to compound peptides for legal sale.<\/p>\n Compounding pharmacies are typically small-scale, local operations that produce variants not pumped out by multinational manufacturers. They can be as minimal as your neighborhood drugstore, and they aren\u2019t regulated by the U.S. government.<\/p>\n Understandably, that makes experts nervous.<\/a><\/p>\n According to a deep dive by The Guardian\u2018s U.S. team<\/a>, compounding pharmacies have historically made \u201cdangerous and even sometimes deadly errors.\u201d The FDA does not verify compounded drugs before they are marketed.<\/p>\n Beyond that, there are fears that the FDA legitimizing peptides may encourage sales from the shady \u201cgrey market\u201d suppliers that are already so popular.<\/p>\n In short, peptides may become widely available in the near future, despite a lack of evidence for their effectiveness and concerns about their future quality.<\/p>\n Peptide risk and doping implications FDA approval or not, it\u2019s very easy to have a big packet of the most popular injectable peptides delivered to your door.<\/p>\n Those who do so are taking a risky gamble.<\/p>\n Human research on drugs like BPC-157 and TB-500 is limited in volume and scope.<\/p>\n Anecdotally, some users have reported short-term side effects including G.I. distress, nausea, abnormal immune responses, and more.<\/p>\n Further to that,the potential long-term hangover of peptides remains unknown. Scientists are pondering the theory that if peptides accelerate cellular repair and blood vessel growth, they might speed tumor development, too.<\/p>\n WADA moved fast when interest in peptides peaked.<\/p>\n In 2022, it moved BPC-157, TB-500, and many other trending peptides onto its prohibited list<\/a>. Those found positive for substances on the list face lengthy bans from their sporting federations, including the UCI<\/a>.<\/p>\n WADA classifies BPC-157 as SO, \u201ca non-approved substance.\u201d<\/p>\n BP-500 joins other leading wellness peptides like MK-677 in the S2 category. S2 is the domain of villainous performance enhancers EPO and hGH.<\/p>\n Peptides at a tipping point in the US?<\/p>\n For now, popular peptides are not formally approved by the FDA for pharmacy compounding.<\/p>\n For now.<\/p>\n The recent momentum \u2014 and maybe some political pressure \u2014 suggests it\u2019s likely only a matter of time before the agency acts on the committee vote to make them more widely available.<\/p>\n In the UK, peptides don\u2019t have marketing authorization from the government\u2019s medical regulatory agency (the MHRA). In Canada, injectable peptides are highly regulated. Their production is subject to government authorization.<\/p>\n All that said, it\u2019s ridiculously easy to pick up a bottle of PBC-157 and TB-500, ignore the \u201cfor research use only\u201d warnings, and wait for the Wolverine gainz.<\/p>\n The amateur grey area: Treatment or enhancement? WADA confirmed to Velo that an FDA approval would not change its ban on peptides. They\u2019re strictly off-limits for pros now, and will remain so, irrespective of the U.S. government\u2019s stance.<\/p>\n It\u2019s not so straightforward for amateur athletes.<\/p>\n For casual riders suffering a nagging bout of tendinitis, they\u2019re a very tempting, seemingly innocent proposition.<\/p>\n A regular load of \u201cWolverine\u201d peptides might enable them to make the start of the bucket-list 200-miler they\u2019ve dreamed of for years, or maybe just join friends on the weekend group ride.<\/p>\n However, peptides sit in a more ethically awkward spot for hard-training age-groupers chasing podium finishes at lucrative gravel races and road fondos. Big payouts and sponsorship opportunities can be on the line for these athletes who train 20 hours a week while holding down a 9-5.<\/p>\n For these \u201celite amateurs,\u201d peptides blur the line between \u201cmedical treatment\u201d and \u201cillegal enhancement.\u201d The Cameron Hanes controversy proved how heated the debate over \u201cthe spirit of sport\u201d can get.<\/p>\n Our take?<\/p>\n Peptides are unproven, risky, and depending on the supplier, extremely costly.<\/p>\n
