PT-141 (Bremelanotide) — Melanocortin Receptor Agonist

Regimen is the PT-141 tracker app for people using bremelanotide for sexual health. PT-141 has specific timing and dosing considerations that make tracking valuable — when you took it, how long until onset, your response, and any side effects like nausea or flushing. Regimen logs every dose, tracks your personal timing patterns, and keeps a private record of your protocol — with half-life data sourced from published clinical studies and FDA prescribing information. Free — every feature unlocked for your first compound. No paywall, no trial, no credit card. 4.8 stars on iOS and Android.
Why Track PT-141 with Regimen?
Timing and onset tracking
PT-141 is typically administered 45 minutes to several hours before desired effect. Tracking your personal onset time across multiple uses helps you dial in timing for your physiology.
Side effect logging
Nausea and flushing are common PT-141 side effects. Log severity per dose to identify your optimal dose and whether side effects diminish with use.
Dose optimization
PT-141 dosing (typically 1-2 mg) may need adjustment. Track your dose and response to find your personal effective dose.
Frequency monitoring
PT-141 has a recommended maximum frequency (not more than once in 24 hours, not more than 8 times per month per the Vyleesi label). Regimen tracks your usage frequency.
Share and export your data
Share your stack and health metrics with your practitioner, export your full dose history, or keep it for your own private records.
