The Compound Index · v1 · 55 entries · weekly updates

The living index of what works, what doesn't, and what's contested.

Every entry: evidence tier (1–4), half-life, MW, cost-per-mg, and the one sentence on what the community has wrong. Every compound in our calculator links here. Every COA-scored vendor links here. Research use only — no clinical recommendations.

Evidence tiers: Tier 1 — FDA-approved / strong human RCT Tier 2 — published human trial; possibly off-label Tier 3 — mechanistic + animal; human data thin Tier 4 — community + n=1; mechanism plausible

Costs are median vendor prices in May 2026, $/mg of active compound. Half-life is plasma unless noted. RUO peptides are research-use-only; nothing here is a recommendation to use compounds on humans or animals.

Use the index, do the math, verify the vendor.

This index is the map. The calculator does your reconstitution math. The COA Truth Index scores your vendor. The newsletter ties them together every Sunday.
