Compound library

55 GLP-1 medicines and peptides, graded by how well each has been measured in people. Half-life, form, storage and study count for every one. Never a dose, never a recommendation.

SABCDHow we grade evidence · depth of human research, never a recommendation

A grade answers one question: how well has this been measured in people? It says nothing about whether something is right for you. Your prescriber decides that.

Grade S
FDA-approved
Approved by the FDA for a named use after Phase 3 trials. The best-measured tier.
Grade A
Human trials
Several randomized, controlled human trials published, no FDA approval for the use people reach for.
Grade B
Human studies
Controlled human studies or clinical series exist, but not at Phase 3 scale.
Grade C
Early human data
Small human pilots or observational reports, with most of the literature in animals or cells.
Grade D
Lab and animal only
Animal or cell studies only. No controlled human data published yet.

Grades come from the published human literature as of October 2026 and are refreshed with each release. A high grade is not a recommendation; a low grade is not a verdict.
