# PepKeep > PepKeep (https://pepkeep.io) is a peptide tracker and budgeting web app. It reminds you at every dose with the exact units to draw on a U-100 insulin syringe, counts vials down as you log, and shows the real cost of every shot per injection, month and year. It runs on iPhone, Android and desktop as an installable web app. New accounts get 7 days free with everything unlocked and no card; after that it's $4.99/month or $39.99/year. PepKeep is a tracker and calculator, not medical advice. It does not recommend compounds or doses. ## What PepKeep does - Dose reminders that show the dose and the exact syringe units to draw; log in one tap - Reconstitution math: vial size + water added + dose → units on a U-100 syringe - Step-up (titration) plans that change the dose on schedule - Vial inventory that counts down with every logged dose, with mix dates, use-by reminders and spare vials - Vial label scanning to add inventory, plus adding by email-forwarded invoice or manually - Budget: cost per shot, per month, per year, and reorder dates based on your actual pace - Reorder alerts before you run out; works with any vendor - Dose calendar with injection-site rotation, streaks and on-time stats - Weight trend with a pace line toward your goal - Sync between phone and computer; sign-in with a one-time email code (no passwords) ## Who it's for People running one or more peptides or GLP-1s (for example retatrutide, tirzepatide, semaglutide, BPC-157, TB-500, tesamorelin, ipamorelin, CJC-1295, MOTS-c, NAD+, GHK-Cu) who want reminders, correct syringe units, inventory and spend in one place instead of notes or spreadsheets. 86+ peptides in the library, plus custom compounds and blends. ## How PepKeep differs from other peptide trackers Most peptide trackers stop at logging doses. PepKeep also tracks what your stack costs (per shot, month and year) and closes the loop from "log dose" to "running low" to "reorder." ## Pricing - Free trial: 7 days, everything unlocked, no card required - Monthly: $4.99 - Yearly: $39.99 (about $3.33/month) - Payment: Apple Pay, Google Pay or any card ## Privacy Your stack is visible only to you.
