Peptide therapy deserves better than a notes app and a guess. PepShot is a private record-keeping tool for treatment plans provided by your clinician or pharmacy. Enter your prescribed dose and schedule, then keep administrations, reminders, injection sites, vials, and history in one place. PepShot requires a paid PepShot Pro subscription.

Included with PepShot Pro (paid subscription required): • Today dashboard —> what's due, streaks, and 7-day adherence at a glance • Dose log —> record the amount administered; PepShot never calculates it • Site history —> review previously recorded injection sites • Cycles —> weeks-on / weeks-off handled automatically • Vial inventory —> what's left, days since reconstitution, reorder warnings • Dose reminders —> quiet nudges at your dosing windows • History —> calendar view, weekly trends, CSV export No account. No login. No cloud sync. Your protocol - every peptide, dose, site, and note - lives on your device, not on someone else's server. PepShot does not calculate or recommend medication dosages and does not provide medical advice, diagnosis, or treatment recommendations. Enter only the dose and schedule supplied by your licensed clinician or pharmacy.
