PepCalc is a peptide research reference and protocol tracker. Browse research summaries and linked references, save your protocols, and keep a schedule and log. Features: RESEARCH LIBRARY: Profiles of 18 peptides with research applications, mechanism of action, regulatory status, and known risks where documented, plus more than 200 linked references. Search by name or browse by category. SAVED PROTOCOLS: Save each protocol you already follow, using values you already know. Name it and add formatted notes with headings and lists. Every protocol is there when you come back. BLENDS: Keep the labeled contents of a pre-blended vial together in one protocol. SCHEDULES: Tap Add a Schedule on a saved protocol and choose every day, certain weekdays, once a week, or days on and days off, with an optional end date. Reminders let you log right from the notification without opening the app. TODAY VIEW: See everything scheduled for the day, in order. Tap Log to review the entry, change anything that was different, and save it. HISTORY: Scroll back through every month as a color-coded calendar showing the days you completed, partly completed, skipped, or didn't log, and how much of each month's schedule you kept. Tap a day to review or fix its entries. Tap a month to see when you completed each entry compared with its scheduled time. SHARING AND IMPORT: Share a protocol as a link, or as an image with a QR code when it fits. Other PepCalc users can import it by opening the link or scanning the code with their camera. THEMES: Several themes, each with light and dark modes. PRIVATE BY DESIGN: No account required. Your protocols and logs are stored on your device, and you choose which protocols to share. DISCLAIMER: PepCalc is for research and educational use only. It is not for medical use, does not provide medical advice, and does not suggest or recommend amounts.
