FAQ
Questions, answered.
What's the best peptide tracker app?
It depends on scope. Injectly is great if you want free injection tracking with concentration insights; Pep AI if you want depth plus nutrition and AI; Dosefi if you track peptides alongside injectables, microneedling, skincare, or supplements in one log.
Do peptide tracker apps do reconstitution math?
The better ones do. Dosefi, Pep AI, and dedicated calculators handle vial concentration and reconstitution so you don't do the math by hand.
Is a peptide tracker medical advice?
No. These apps are recordkeeping and educational tools, not medical services. Always work with a qualified, licensed professional.
