Peptmate is a calm, private home for tracking research peptides. Log every dose in a tap, let the app handle the math, and see your whole protocol at a glance. NEVER MISS A PIN Set schedules per peptide, get reminders at the times you choose, and log a dose in one tap. Your streak, your calendar, and your history stay in sync. NEVER DO THE MATH Enter your vial strength, water, and target dose once. Peptmate shows exactly how many units to draw. Reconstitution math, unit conversions, and supply tracking are handled for you. YOUR WHOLE JOURNEY, NOT JUST TODAY Peptmate tracks each peptide across vials: reconstitute, use, run empty, refill, and keep the full history. Activity logs record every lifecycle event so your long-term record stays complete. TRACK HOW YOU FEEL Log mood, weight, and free-text journal notes alongside your doses. Trends and insights show your own patterns over time, in your own data. LEARN AS YOU GO A plain-language library covers common research peptides, with evidence-level labels on studies, a glossary that skips the jargon, and short lessons on the practical basics. PRIVATE BY DESIGN Your data belongs to you. No ads, no trackers, no selling your information. Sign in with Apple, Google, or email; your record syncs securely across devices, and you can delete your account and all data in the app at any time. CALM, NOT CLINICAL Designed to feel like a considered companion rather than a spreadsheet: quiet colors, clear type, and one-tap actions for the things you do every day. Peptmate is a tracking and information tool. It does not provide medical advice, diagnosis, or treatment, and it does not sell or supply any substance. Always consult a qualified healthcare professional about decisions that affect your health. Terms of use: https://peptmate.com/terms Privacy policy: https://peptmate.com/privacy
