Experimental peptides such as BPC-157 are always doping: they fall under WADA category S0, non-approved substances. Peptide hormones and growth factors (S2) are also always prohibited. Ordinary proteins such as whey and collagen are allowed, provided the product has been tested for prohibited substances.
Why athletes need to take extra care
For athletes who take part in competitions, the rules of the World Anti-Doping Agency (WADA) apply. Those rules are stricter than ordinary law: something can be legally on sale and still be doping.
Two categories on the doping list
- S0 – Non-approved substances. Anything that has not been approved by any government as a medicine for human use is always prohibited. WADA has explicitly named BPC-157 as an example here since 2022 (UKAD). The category itself has existed since 2011 (Deutsche Sporthochschule Köln).
- S2 – Peptide hormones and growth factors. These include growth hormone and substances that stimulate its production. These too are always prohibited, both in and out of competition.
What is allowed, then?
Ordinary dietary proteins such as whey protein, casein and collagen peptides are not on the list. The risk lies mainly in contamination: supplements can unintentionally contain prohibited substances. So choose products with an anti-doping quality mark, such as NZVT in the Netherlands or Informed Sport.
Who is responsible?
The athlete themselves. 'I didn't know' or 'it wasn't on the label' is not a valid defence. Unsure about a product? Use the Dopingwaaier (the Dutch medicines doping check) or contact the Dopingautoriteit (Dutch Doping Authority).
In short
BPC-157 and similar experimental peptides are doping, always. Ordinary protein powders and collagen are allowed, provided you choose a tested product.
Frequently asked questions
Is BPC-157 doping?
Yes. BPC-157 falls under WADA category S0 and has been explicitly named as an example since 2022. It is always prohibited, both in and out of competition.
Can I use collagen as an athlete?
Yes, collagen peptides are not on the doping list. Do choose a product with an anti-doping quality mark such as NZVT or Informed Sport.
