The peptide library
Every compound carries an explicit evidence grade, assigned from its published evidence position rather than from how widely it is discussed. Several of the most popular compounds here sit in the weakest two tiers.
Research use only. Not for human consumption. Not medical advice. 18+.
How grading works
Four tiers. A compound being widely sold does not raise its grade.
| Grade | Count | Meaning |
|---|---|---|
| Approved medicine | 8 | Approved by a recognised medicines regulator somewhere in the world. |
| Human trial data | 3 | Human trial evidence exists and is not hedged, but the compound is not approved. |
| Limited human data | 14 | Some human evidence, explicitly hedged, unreplicated, or largely mechanistic. |
| Preclinical only | 11 | Animal or mechanistic evidence only, with no completed human trials. |
Grading is deliberately negation-aware: an evidence note reading “no human trials” or “not yet approved” is resolved as a denial before any positive match is considered, because those phrases contain the exact wording a naive classifier would match on and would otherwise invert the grade.
