The three things only Pinned does.

Vendor verification, built in

Scan any vial. Get a live trust score from Finnrick, Janoshik, and PeptideScores public lab data. No other peptide app does this.

Optimizer, not just a logger

A 0-100 stack score that finds mechanism conflicts and gaps before they cost you a cycle. Other apps log what you took. Pinned tells you what's wrong with it.

Real cycle modeling

Run actual 8-on / 4-off cycles with receptor resensitization windows — not just "rest days." Pinned models how peptides actually work, not how a calendar does.
