The US Just Opened the Door to the Wolverine Stack. In Canada, Those Peptides Are Still Illegal.
HHS will let US compounding pharmacies make six unapproved peptides, including BPC-157. Health Canada still bans them online, but a CBC investigation found a loophole.
C-Tribe Editorial
The "Wolverine stack" just went semi-legit in the United States. On October 28, the US Department of Health and Human Services said the FDA will not act against licensed compounding pharmacies that make six unapproved peptides, including BPC-157 and TB-500, the injectable pair sold under that superhero nickname, according to the FDA Law Blog. The other four are epitalon, KPV, MOTS-c and semax.
This is not an approval. HHS itself says "the policy does not grant FDA approval or establish clinical safety and effectiveness," as Medical Daily reported. FDA scientists found the five clinical studies of BPC-157 were "short, small and insufficient to establish safety or effectiveness," and that there were no human safety studies at all for KPV, TB-500, MOTS-c or epitalon. In Canada, four of those six peptides are on Health Canada's warning list.
Why Did the US Loosen the Rules on Peptides?
Because the health secretary is a fan. "I'm a big fan of peptides. I've used them myself and with really good effect on a couple of injuries," Robert F. Kennedy Jr. said on Joe Rogan's podcast in February, according to the Associated Press. HHS framed the change as a way to pull people away from "black-market peptides," NBC News reported.
The process drew sharp criticism. An FDA advisory panel voted 8-6 in July on three of the peptides, and an industry safety group says the eight members Kennedy added made up the entire yes side, per Medical Daily. Six newly named panelists had sold peptide products, Benefits and Pensions Monitor reported. Former acting FDA commissioner Janet Woodcock called the broader push "a disruption of the societal pact we have had since 1962," according to ProPublica.
Business moved fast. Telehealth companies are already selling peptide programs for US$199 to US$249 a month, and analysts project a US$3.3 billion market by 2030, Time reported.
Are Peptides Like BPC-157 Legal in Canada?
Not as injectables sold online. Health Canada's April advisory says unauthorized injectable peptides "are illegal in Canada and have not been assessed for safety, efficacy, and quality," and that "Research Use Only" labels do not exempt them, in a public warning that names BPC-157, TB-500, epitalon, KPV, MOTS-c and the copper peptide GHK-Cu. The agency works with the Canada Border Services Agency to stop shipments.
It has gone to court too. In June, Quebec Superior Court granted Health Canada a permanent injunction against Canlab Research, an online seller the agency had warned about since 2023, according to a Health Canada release. An earlier advisory on another seller, Canada Peptide, listed more than 40 unauthorized injectable peptides seized or sold.
Alberta's doctors got a direct heads-up. The College of Physicians and Surgeons of Alberta told physicians in April to ask patients about injectables bought online and listed BPC-157 among the unauthorized products.
Is There a Peptide Loophole in Canada?
A CBC investigation says yes. Some doctors in Ontario and British Columbia are prescribing BPC-157 as a "compounded natural health product," CBC reported in July. Health Canada told CBC that BPC-157 has not been authorized and that there is "limited scientific evidence to support its use."
McMaster University researcher Stuart Phillips explained the gap to Benefits and Pensions Monitor. BPC-157 "slips through as a compounded natural health product, where the federal safety check basically doesn't happen." University of Alberta health law professor Timothy Caulfield called the situation "maddening."
The evidence gap is wide. Phillips helped screen 544 papers on BPC-157 for a systematic review and found only one human study among the 36 that qualified, he wrote in The Conversation. The human data that exists covers a few dozen people. "Very few of them have actual benefits," UBC's Bob Hancock told CTV News.
Who Made Peptides Go Mainstream?
Podcasters and creators, mostly. Tens of thousands of people share peptide "stacks" on TikTok and Instagram, Time reported in February, and 20% of tested samples were mislabeled. "People are taking them on blind faith," cardiologist Eric Topol said. Andrew Huberman, who has more than 16 million followers, has cited mouse studies suggesting BPC-157 has "very high safety profiles," KFF Health News reported, alongside cases of people hospitalized after peptide injections.
Platforms are starting to pull back. TikTok now returns error pages for searches like BPC-157, semaglutide and retatrutide, while leaving videos up, YPulse reported. In Canada, the Competition Bureau told brands back in 2020 that "influencer marketing is not a way around the law," in a warning to about 100 companies, and it now shares complaints about misleading health claims with Health Canada under a 2023 agreement. A University of Alberta study in the Canadian Journal of Bioethics concluded that current enforcement is not enough and called for "updated, scalable, and equitable regulations."
What Happens Next for Canadians?
Expect more pressure at the border. US compounding pharmacies can now make products that remain illegal to sell here, and US telehealth brands already market to Canadians. Health Canada's approach so far has been warnings, seizures and court orders aimed at sellers, and the CBC loophole shows how easily products can slip past that.
For creators in the wellness space, the line is clearer than the hype suggests. Canadian ad rules hold influencers to the same standard as brands, and promoting an unauthorized injectable is promoting an illegal product. Washington has decided to let people take the risk. Ottawa has not, and anyone selling a stack to a Canadian audience is operating under Ottawa's rules.
