About Petal: Your Peptide Companion
The beautifully designed peptide companion. For women in their best-self era. Petal makes the math safe, the research trustworthy, and your progress visible. A concentrated app for three things - and three things only: - RECONSTITUTION MATH The dose math that you used to cry over, made simple. Vial size, BAC water, desired dose - Petal gives you the exact units to draw on an animated syringe diagram. No more 2am Reddit threads. No more squinting at a slin pin. - RESEARCH LIBRARY + AI Q&A A curated library of peer-reviewed studies on BPC-157, GHK-Cu, MOTS-c, TB-500, semaglutide, tirzepatide and more - written by humans, citing real research, honest about limitations. Each peptide includes a "For women" section because most peptide research excludes women, and we think you deserve to know that. Ask the AI any question about the science. It's bounded to our curated corpus and refuses dosing recommendations - those belong with your clinician. - INJECTION SITE ROTATION A first-class body map showing your last 14 days of injection sites, color-coded by recency. Tap "next safe site" and Petal suggests where to go. Beautiful, clean, female-default illustration. - THE GLOW JOURNAL (THE RITUAL) Once a week, take a selfie. Petal stores it on your device - never uploaded, never shared. Compare any two weeks with a slider. Watch yourself bloom over a 12-week protocol. Photos stay on this device. They are never uploaded. Period. Health Disclaimer Petal is designed for tracking and educational purposes only. It is not intended to provide any medical guidance or advice.
