What users are saying
4.9 on the App StoreBest health app I've downloaded in years
Not exaggerating — this is the most useful health-related app on my phone. The peptide library is comprehensive, the calculator is dead accurate, and the protocol tracker keeps me honest. Five stars easy.
Switched from three other apps
I was using one app for tracking, another for calculations, and a spreadsheet for my protocol schedule. PeptideFox replaced all three. Everything in one place, beautifully designed, and actually reliable.
Perfect for beginners
Just getting started with BPC-157 and was overwhelmed by all the dosing info out there. This app made it simple — the library cards explain everything clearly and the calculator handles all the math. Wish I'd found it sooner.
