## What is OnePin?

OnePin is the protocol tracker built for people who actually run peptides and supplements - not a glorified pill reminder.

WHAT IT DOES

- Track every peptide, supplement, and dose across complex multi-phase protocols
- Smart syringe grouping with built-in compatibility checks (avoid lists, safe lists, contamination warnings)
- Phase-aware dose calculations that handle taper, escalation, and break cycles automatically
- Vial life math, doses-per-vial, supply forecasting per cycle
- Day-by-day calendar with cycle countdowns and rest-day awareness
- Inventory tracking with batch dates, costs, vial-tracking, and phase-aware capacity projections
- Body map injection site tracker with heat-map awareness so you rotate sites
- Protocol templates for popular compounds, with editable starting points
- Compliance dashboard, dose history, and dose-log audit trail
- Compound database covering peptides, supplements, blends, and bioregulators
- Household sharing - track for yourself plus a partner from one app

CYCLE TYPES SUPPORTED

- Indefinite (daily / EOD / weekly / specific days)
- Yearly Schedule (auto-spaced cycles per year, e.g. 3x/yr bioregulators)
- Fixed Count (run N cycles then stop, with end-date preview)
- Custom phases with per-slot dose escalation

INTERACTION SAFETY

- 200+ compound database with curated avoid / safe pair data
- Real-time syringe planner that flags REACTIVE compounds (GHK-Cu, glutathione, SS-31, LL-37, etc.) and isolates them per chemistry safety rules
- Same-day dosing interaction warnings across routes
- Bioregulator-specific grouping logic

WHO IT'S FOR

If you're running anything more complex than "1 peptide, daily, forever", you've felt the pain of spreadsheet-tracking peptide protocols. OnePin replaces that spreadsheet.

Designed for: research peptide users, supplement biohackers, protocol designers, household partners managing each other's protocols, anyone running multi-phase or cycle-based regimens.

NOT INTENDED FOR

OnePin is a tracking and education tool. It does not provide medical advice. Compounds tracked are sourced as research chemicals or supplements; verify dosing with a physician before use. The app does not validate the safety or legality of any compound or protocol you enter.

PRIVACY

Your data stays yours. Local-first storage with optional cloud sync via your account. We don't sell or share your data.

### 5/5 — A game changer for my health journey!

*2026-07-05*

⭐⭐⭐⭐⭐

This app has truly become such an important part of my wellness transformation. Starting a healthier lifestyle can feel overwhelming when you’re trying to keep track of supplements, schedules, routines, and your progress — but this app brings everything together in one easy place.

It has helped me stay organized, consistent, and more confident with my daily health goals. I love being able to look back, track what I’m doing, and stay accountable instead of trying to remember everything on my own

### 5/5 — Great app

*2026-07-05*

Such a great and helpful app!! 10/10 recommend!

### 5/5 — Highly recommend

*2026-06-01*

I’ve tried a lot of different ways to track peptides, TRT, supplements, and dosing schedules, and OnePin is by far the most organized system I’ve found. The interface is clean, easy to navigate, and makes it simple to keep track of multiple compounds, injection schedules, and daily protocols all in one place.

What I like most is that it takes the guesswork out of protocol management. Instead of keeping notes in multiple apps or trying to remember what I took and when, everything is laid out clearly with reminders, tracking, and completion status.

The developers also seem committed to improving the app, which is something I appreciate. If you’re running a detailed health, fitness, hormone, peptide, or supplement protocol and want a professional way to stay organized, OnePin is absolutely worth trying.

### 5/5 — So helpful

*2026-06-01*

This app makes peptide dosing way easier. It helps you combine multiple peptides into one shot, keeps track of injection sites so you can rotate properly, and manages your inventory so you always know how many doses and vials you have left. Also has a feature to upload your labs to keep bloodwork in one place and see how doses change your labs! Super cool once you get the hang of it!

### 5/5 — Great App

*2026-05-31*
