The WADA list and peptides
Most of this catalogue is prohibited in organised sport — not ambiguously, not arguably, prohibited. If you compete under anti-doping rules, this is the page to read before any other on this site, and we would rather lose the order than skip the warning.
Private rules, real consequences
The World Anti-Doping Code is not criminal law. It is a rulebook that athletes accept by competing, enforced through testing and tribunals, with sanctions measured in years of eligibility. That private character makes it stricter than law, not weaker: no presumption of innocence about presence, no interest in why a substance was in a sample.
The prohibited list updates every January and names categories as well as compounds. For peptides the decisive categories are S2 — peptide hormones, growth factors and related substances — and the growth hormone secretagogue family within it. Those nets are drawn wide on purpose, catching compounds by mechanism even before they are named individually.
Strict liability completes the system: the athlete is responsible for what is in the athlete, full stop. Contaminated supplements, mislabelled products, a training partner’s vial — the tribunals have heard every version, and the ban lengths say how much the stories helped.
Where our compounds sit under the code
Plainly, category by category.
- 01
The GLP-1 class: check by list year
Semaglutide and its relatives have moved in and out of monitoring discussions. Anything affecting metabolism can change status at a January revision — competing athletes verify against the current list, every season.
The class in question - 02
Growth hormone secretagogues: prohibited
CJC-1295, ipamorelin, tesamorelin and the whole releasing-hormone family sit squarely in S2. This is the least ambiguous corner of the catalogue.
The compounds concerned - 03
Repair peptides: prohibited
BPC-157 is explicitly named; TB-500 and related fragments fall under the same provisions. Their forum reputation as undetectable is both irrelevant to the rule and increasingly untrue.
Both compounds, compared - 04
Melanotan and PT-141: restricted contexts
Melanocortin agonists appear in prohibited categories depending on context and route. The individual pages carry the detail; the safe competitive assumption is: do not.
The compound page
Research supplier, not a sports one
We sell laboratory material for research. We do not market to athletes, we do not write "undetectable" copy, and compound pages carry WADA flags where they apply — the disclaimer at the foot of every page is not there for decoration.
Detection deserves a sober sentence: anti-doping science works backward from mechanism, retests stored samples as methods improve, and has repeatedly caught compounds years after their users believed the window closed. Betting a career on a detection gap is betting against a laboratory with a freezer full of your past.
And the obvious corollary: if you compete, the responsible reading of this entire website is academic. The knowledge base is open to you; the catalogue, effectively, is not. We are comfortable writing that sentence, which is perhaps the most useful thing this page tells you about us.
- The current list outranks this pageWADA revises every January. A static page is a snapshot; wada-ama.org is the instrument.
- Strict liability has no exceptions for intentHow it got there does not matter. That it is there does.
- Retesting reaches backwardStored samples meet improving methods. Today’s gap is next year’s case.
- Therapeutic use exemptions are narrowTUEs exist for documented medical need through proper channels — not as a retroactive explanation.

About the prohibited list
The sport questions we receive and decline to soften.
Is BPC-157 really banned? It is not a hormone.
I compete recreationally — does the code reach me?
Are your products tested for sport?
When does the list change?
The knowledge base stays open
Compete clean, read freely. For laboratory work, the catalogue and its certificates are where they always were.
For laboratory and research use only. Not for human or animal consumption. Not a medicine and not a food supplement. Sold to persons aged 18 and over.
