PeptideOS

The reference that tells you
when nobody knows.

Every peptide app hands you a confident dosing number. Many of those numbers have no human study behind them at all. PeptideOS shows the source for every figure, models what a half-life actually does to a schedule, and says “this is unknown” when it is.

New to peptides? Start here.

Half-life aware

Accumulation, peak-to-trough swing, time to steady state, and loading dose, computed from published pharmacokinetics.

Sourced or silent

A numeric claim without a citation fails the build. Unknowns are labelled unknown instead of guessed.

Error-catching math

Reconstitution in both directions, with warnings for unmeasurable draws and barrel overflows.

Uncited claims

A seed library, not a finished one. Every entry was checked against an FDA label or an indexed paper before it was added, including the 53 where the honest answer turned out to be that no human data exists. Growing the count is easy; growing it honestly is the work.
