Would you consider using unapproved wellness treatments on your pet to manage their health issues?
Dog owners across the United States are turning to unregulated peptides like BPC-157 and TB-500 to treat their pets' arthritis and mobility issues. Experts are raising alarms, citing potential links to cancer and a complete lack of FDA-approved safety data for these substances in animals.
Why it matters
Pet owners often turn to these online-purchased compounds as a cheaper alternative to conventional veterinary care for managing pain. However, without clinical oversight or standardized dosing, these unregulated treatments pose serious health risks to pets.
Owners are purchasing unregulated peptides online and scaling human doses based on weight, with some users reporting initial doses of 500 micrograms that increased to 2 milligrams. These products are not FDA-approved for canine use.
The players
Andrew Huberman
A podcaster and educator with over 1.8 million followers on X who has publicized reports of peptide use.
Ryan Samluk
A Dallas resident whose 11-year-old dog, Finley, was diagnosed with hemangiosarcoma following peptide treatments.
Michael Morelli
A Florida-based individual who operates Pawgen, a brand that sells peptides.
The details
Peptide stacks are frequently marketed for wound healing and inflammation relief, leading owners to believe they can reverse aging or mobility loss. Veterinarians have expressed concern that BPC-157 specifically may stimulate tumor growth through its blood vessel-building properties.
Timeline
In July 2026, Andrew Huberman shared reports regarding peptide use in aging dogs.
In August 2026, Finley, an 11-year-old dog, suffered a sprain.
As of September 2026, experts are cautioning against the administration of these unregulated treatments.
Culture Shift
The rise of DIY peptide use reflects a broader trend of pet owners bypassing traditional veterinary diagnostic paths in favor of online biohacking communities. This shift mirrors modern human wellness fads that increasingly move from clinical settings to unregulated consumer-grade experimentation.
Owners should be aware that administering human-grade peptides carries significant risks because there is no established safe dosage for dogs. Relying on unregulated products can lead to severe health consequences, such as the development of aggressive cancers.
The takeaway
Always consult a licensed veterinarian before introducing any new supplement or treatment to your pet's regimen. Relying on anecdotal advice from social media can lead to dangerous and unintended health consequences for your animals.
