Dose Track combines TRT, GLP-1, and peptide tracking in one privacy-focused app. It reads bloodwork PDFs with AI and has a built-in library of 800+ medications and supplements, with built-in pharmacokinetic data for the medications it models.
Strengths: 800+ medications and supplements, 428 with research pages (how it works, safety, FDA status, studied doses, references), built-in PK data for the medications it models, AI bloodwork PDF analysis, all-in-one (TRT + GLP-1 + peptides), reconstitution calculator, privacy-first (records stored on your phone, no account needed)
Limitations: Newer app (launched Dec 2025)
Shotsy is a dedicated GLP-1 tracker for Ozempic, Wegovy, Mounjaro, and similar medications. It excels at tracking weekly injections with estimated medication level charts, weight/calorie/protein tracking, and side effect monitoring.
Strengths: Purpose-built for GLP-1, medication level estimates, comprehensive health tracking, on iPhone, data stays on the device and in iCloud
Limitations: GLP-1 only (no TRT or peptide support); Android app stores data with Google Firebase — full Dose Track vs Shotsy comparison
TRT Plus is built first for testosterone, on iPhone and Android, with 100+ preset compounds that also cover anabolics, peptides, GLP-1s and SARMs. It models levels for injectables, orals, peptides and creams, has a peptide reconstitution calculator and a site rotation planner, and scans bloodwork from a photo, PDF or spreadsheet into an AI bloodwork report. It also links to Apple Health and has daily check-ins.
Strengths: Deep TRT focus, PK modeling across many compound types, bloodwork scanning
Limitations: Few ratings so far (4.1 from 20 on iPhone, 4.7 from 56 on Google Play); where records are stored is not stated beyond Apple Health data (as of October 31, 2026)
Regimen tracks peptides, TRT, HRT and GLP-1s on iPhone and Android, with a 200+ compound library, four calculators in its Android app (removed from iPhone in October 2026), daily check-ins, Apple Health data and bloodwork on the same charts as your doses.
Strengths: Daily check-ins and labs next to your doses, 200+ compound library, calculators for oils and nasal sprays on Android, CSV import
Limitations: Data synced to its servers; no blends listed (as of October 31, 2026) — full Dose Track vs Regimen comparison
Pep AI is a GLP-1 and peptide tracker that also logs meals, protein, water, side effects and sleep, with an Apple Watch app, widgets and PDF reports for your doctor. iOS and Android.
Strengths: Food and protein logging, side effects next to doses, Apple Watch app, PDF reports, community groups
Limitations: Dose calculator removed in October 2026; no blends listed (as of October 31, 2026) — full Dose Track vs Pep AI comparison
PeptidePal runs several peptide or GLP-1 protocols side by side, handles blends, and projects when each vial runs out. Its Android app does the reconstitution math; the calculator was removed from the iPhone app in October 2026. iOS 18+ and Android.
Strengths: Protocol builder with cycles, blends, vial run-out warnings, compound library, moderated forum, data on device by default
Limitations: No reconstitution calculator on iPhone (as of October 31, 2026) — full Dose Track vs PeptidePal comparison
Peptide Tracker Log & Reminder (Flat Six Labs, peptidetracker.ai) is a tracker with stacks, blends, vial and supply tracking and a community, on iPhone, Android and the web. Its calculators are on the web and Android; the iPhone app no longer calculates doses or draws (October 2026).
Strengths: Blends and supplies, web app, community
Limitations: Account-based (data kept on its servers); no bloodwork listed (as of October 31, 2026) — full Dose Track vs Peptide Tracker Log & Reminder comparison
Zest (Launchpoint Dev Inc., zestfreshtracking.com) is a new peptide tracker. Its website shows a reconstitution calculator with a visual syringe, dose logging with an injection-site body map, reminders, vial inventory with low-vial alerts, a daily check-in for energy, mood, sleep and appetite, a 69-compound research library, guides and Zest AI. Its App Store and Google Play buttons said "coming soon" on October 31, 2026.
What its site shows: Visual-syringe calculator that works without an account, body-map site rotation, low-vial alerts, daily check-in, guides for mixing and injecting (Dose Track has these too)
Limitations: Not in the app stores yet; peptides only, with no GLP-1, TRT, blends or bloodwork listed (as of October 31, 2026) — full Dose Track vs Zest comparison
