You're tracking 4 peptides in Apple Notes.
And doing reconstitution math in your head.
Multi-compound protocol tracking with built-in reconstitution calculators, pharmacokinetic modeling, and dose logging. BPC-157, CJC-1295, TB-500, Ipamorelin, GHK-Cu — all tracked separately, all in one app.
The problem
PeptIQ tracks doses. PeptideCalc does math. Neither does both.
You've got a reconstitution calculator bookmarked in Chrome, dose logs in a notes app, and a Reddit thread saved for your BPC-157 protocol. Your stack has 4 compounds with different reconstitution volumes, different dose schedules, and different vial expiry dates. No single tool tracks it all.
What Peptides users get
Built around your protocol.
Reconstitution calculator
Enter your vial size, BAC water volume, and desired dose — Doseline calculates the draw volume. Saves your reconstitution profile per compound so you don't redo the math every time.
mg → mcg conversion · BAC water ratios · Per-vial tracking · Expiry dates
Multi-compound stacking
BPC-157 morning and evening, CJC/Ipa before bed, TB-500 twice a week. Each compound gets its own schedule, dose log, PK curve, and injection site tracking.
Unlimited compounds · Independent schedules · Stack overview dashboard
Pharmacokinetic modeling
See estimated serum levels for each peptide based on published half-life data. Know when your BPC-157 trough hits, when your Ipa peak is, and how stacking affects accumulation.
BPC-157 · CJC-1295 DAC · Ipamorelin · TB-500 · GHK-Cu · Semaglutide · 30+ more
Smart reminders per compound
Different peptides, different schedules. Doseline sends reminders per compound, not per protocol. Your twice-daily BPC and your twice-weekly TB-500 don't share an alarm.
Per-compound scheduling · Frequency-aware · Batch reminders for simultaneous pins
Bloodwork and biomarker tracking
Log IGF-1, GH, inflammatory markers, and anything else you're monitoring. See trends over time, correlated with your protocol changes.
