Feature Guide
NewA complete reference for every OptiPin feature, organized the way you'd actually use them. Each section maps to what's in the app today: tracking, calculators, estimated levels, Apple Health integration, AI summary, inventory, backup, and privacy.
Best for: deciding whether OptiPin fits your workflow, finding a feature you've heard about, getting oriented after install.
Browse the feature guide →Medication Library
200+ compounds across TRT, GLP-1, growth peptides, fat loss, longevity, cognitive enhancers, and supplements. Each entry has typical dosing, half-life, and route notes, the same reference the OptiPin app draws from.
Best for: looking up a specific compound, comparing options within a class, getting dosing references.
Browse the library →Peptide Beginner's Guide
End-to-end walkthrough for first-time peptide users: vial reconstitution math, BAC water selection, syringe units, injection sites, storage, and the most common mistakes that ruin a vial.
Best for: first peptide cycle, BPC-157, GH peptides, anyone reconstituting from lyophilized powder.
Read the guide →TRT Injection Guide
Step-by-step injection technique for testosterone: intramuscular vs subcutaneous, needle gauge selection, draw and inject sequence, the seven main injection sites, and post-injection care.
Best for: first TRT shot, switching from IM to SubQ, dialing in technique to reduce post-injection soreness.
Read the guide →App Walkthrough
A guided tour of the OptiPin app: setting up your protocol, logging doses, reading the estimated-levels view, importing labs from Apple Health, and getting the most out of the AI summary.
Best for: new OptiPin users, anyone who wants to see what the app does before downloading.
View the walkthrough →Peptide Reconstitution Calculator
Free ToolInteractive calculator for every common peptide vial. Enter vial size, BAC water added, and target dose to compute the exact syringe units. Supports 200+ medications with typical dosing hints and one-tap blend expansion for popular stacks (Wolverine, GLOW, KLOW, GH Stack, Healing & Inflammation, Growth + Healing, Anti-Aging).
Best for: every peptide user. The single most-cited error mode in peptide protocols is reconstitution math, this removes it.

The guides above cover technique. The pillars below cover the broader clinical context: who qualifies, what labs matter, what the evidence actually says, and what to do when the protocol isn't working.
TRT Pillar
Diagnosis, dosing, TRAVERSE, hematocrit, supraphysiologic considerations.
GLP-1 Pillar
Compound choice, titration, side effects, switching, maintenance.
Peptides Pillar
Categories, evidence, regulatory state, building a protocol.
Cross-cut topic hubs spanning all three pillars:
Track Your Protocol in OptiPin
Log doses, forecast hormone and compound levels, rotate sites, daily symptom check-ins, and lab tracking, all private and on-device.
