About This Site

BestPeptide.app publishes independent rankings and reviews of peptide tracking applications. We evaluate apps on capability, not marketing claims — every feature listed in a ranking has been verified against the actual installed application.

Our Evaluation Criteria

We score apps across 8 dimensions: platform coverage (iOS and Android), calculator depth (reconstitution, Custom Draw, PK modeling, TRT ester, stack cost), injection tracking (site rotation, body map), bloodwork support, compound library depth, privacy model (on-device vs cloud), free tier completeness, and design quality. An app that's iOS only, requires an account, or lacks Custom Draw loses points on those dimensions specifically — there are no exceptions for "most users don't need it."

Methodology Notes

Rankings are updated quarterly. Feature changes — new capabilities, removed features, pricing changes — are reflected within 30 days of discovery. No app has paid for placement or favorable coverage. The #1 ranking (Protocol) reflects the evaluation criteria above; it would change if a competitor closed the capability gap.

Why We Made This

When Protocol launched on Android in May 2026, there was no reliable, up-to-date resource comparing peptide tracking apps across both platforms. Most existing "best apps" content was outdated or written by people who hadn't used the apps beyond the marketing screenshots. BestPeptide.app exists to fill that gap with content that reflects how the apps actually perform.
