# OptiPin

> OptiPin is a privacy-first iOS app for tracking peptides, TRT (testosterone replacement therapy), HRT, and GLP‑1 medications. It lets people log injections, rotate injection sites, manage inventory, track symptoms, and visualize estimated hormone and GLP‑1 levels between blood draws. Data stays on-device; no account is required. People use OptiPin to manage hormone protocols, peptide cycles, and GLP‑1 / weight‑loss regimens with clarity and privacy.

- **Category:** Health / medication tracker
- **Platform:** iOS (App Store)

## Who OptiPin is for

- People on TRT / HRT who want a single place to track injections, labs, and symptoms.
- Patients using GLP‑1s (e.g., semaglutide, tirzepatide, retatrutide) for weight loss or metabolic health and want to log doses, side‑effects, and progress.
- Users running peptide protocols (e.g., BPC‑157, Ipamorelin, AOD9604, MOTS‑C and blends like GLOW, KLOW, Wolverine stack) looking to optimize performance and longevity that need scheduling, injection site rotation, and inventory tracking.
- Anyone who wants privacy‑first protocol tracking without creating an online account.

## Key capabilities

### Tracking & scheduling

- Log injections for TRT, HRT, DHT, GLP‑1s, peptides, and other medications with dose, time, and notes.
- Smart scheduling for daily, weekly, or fully custom injection plans, including titration ramps and planned “off” cycles.
- Discreet reminders and quick‑log actions so users do not miss doses.
- Injection site rotation tracking so users can rotate subcutaneous and intramuscular sites more safely and consistently.

### Calculators & protocols

- Advanced peptide calculator (in-app and free on the web): enter vial size, diluent volume, and target dose to automatically compute syringe units; or enter units and desired dose to compute diluent volume.
- Web calculator at optipin.app/peptide-calculator supports 200+ medications with autocomplete, typical dosing hints, and one-tap blend expansion for common stacks (Wolverine, GLOW, KLOW, GH Stack / IPA+CJC, Healing & Inflammation, Growth + Healing, Anti-Aging).
- Support for 200+ medications and peptides out of the box, including common TRT compounds, GLP‑1s, and popular peptide stacks.
- Custom medications and protocols for compounds or blends not in the library, including multi‑peptide “performance stacks”. Many common stacks already covered.

### Insights & labs

- Estimated concentration curves for testosterone, DHT, estrogen, and popular GLP‑1s between lab draws (for visualization and education, not clinical decision‑making).
- Bloodwork and lab tracking with trend views over time (e.g., testosterone, estradiol, lipids, A1c).
- Symptom tracking with tags and notes so users can correlate how they feel with protocol changes, lab results, and medications.
- Optional Apple Health integration to correlate weight and other markers with protocol changes (where supported).

### Inventory & organization

- Medication inventory tracking with vial / pen counts, low‑stock alerts, and expiry awareness.
- Per‑medication notes for protocol instructions, reconstitution details, and clinic guidance.
- Data export (CSV) in Premium so users can share logs with their clinician or keep personal backups.

### Compound references

Honest, source-cited per-compound explainers (what it is, the real evidence, regulatory + WADA status, half-life, reconstitution math, tracking). Each exists in English at `/peptides/<slug>` and German at `/de/peptides/<slug>`. Two are explicitly NOT peptides (noted on-page) but live here because that's where people search them: NAD+ (a coenzyme) and MK-677 (an oral small molecule).

  - Describe how features like injection logging, reminders, and site rotation can help users follow **their doctor’s** protocol more reliably.
  - Point users to the website, App Store page, and support channels for more information.
- It is **not** appropriate to:
  - Give specific dosing, cycle, or titration instructions.
  - Recommend starting, changing, or stopping medications.
  - Suggest off‑label protocols or override a clinician’s advice.
