The peptide protocol companion.

Reconstitution math, pharmacokinetic decay curves, injection logging, and a library of 100+ compounds. Built for the people who take their protocols seriously.

No spam. One email when we launch.

The app

A complete protocol tool. Not another tracker.

Three views, all working together. Real data. Real citations. No guesswork on dose math or when your next injection lands.

105 compounds with half-lives, dose ranges, storage, and reconstitution defaults. Searchable, filterable.

The problem

You're running 3 peptides. Your tracker handles one.

Every GLP-1 tracker on the App Store is built for semaglutide users. If your stack includes BPC-157, TB-500, ipamorelin, or anything beyond the one-shot-per-week GLP-1 pattern, they fall apart.

PinPal was built from the first protocol logged. Multi-peptide is the default, not an afterthought.

Six compounds · four categories · half-lives spanning 12 minutes to 7 days. A single-peptide tracker can't reason about this.

Features

Built for the daily driver.

Protocol engine

Every dose, every window, logged.

Tap-to-log injections tied to peptide, dose, site, and time. Miss a dose and PinPal rebalances the schedule — no guesswork on the next window.

Reconstitution math

The math you were going to do on a napkin.

Pick your peptide, enter vial and bac water, set the target dose. PinPal returns the exact draw in U-100 insulin units.

Pharmacokinetics

Decay curves plotted against your real half-lives.

First-order exponential decay for every compound in your stack, modeled against published clinical half-lives. See when the last dose clears and when the next lands.

Symptom intelligence

Side effects, correlated — not just logged.

Daily check-ins map symptoms against dose, site, and time. PinPal surfaces the patterns you'd miss in a notes app.

Site rotation

Rotate sites the way clinicians recommend.

A 2D body map remembers your last eight injection sites per peptide. Keep the rotation clean without burning out the same spot.

Provider share

Export a clean report for your provider.

One-tap PDF with your protocol, dose log, symptoms, and weight trend. Built for longevity clinics and telehealth providers.

Grounded in evidence

Every decision cited. Every number checked.

Questions

The ones we get most often.

  • No. PinPal is a tracking and information tool. It does not diagnose, treat, or prescribe. Every dose, interaction, and side-effect note is for informational purposes only. Always consult your healthcare provider before starting or changing any peptide protocol.

  • At launch: 105 compounds across GLP-1s (semaglutide, tirzepatide, retatrutide), healing peptides (BPC-157, TB-500), growth hormone secretagogues (sermorelin, CJC-1295, ipamorelin), and cosmetic peptides (GHK-Cu, epithalon). We add compounds continuously based on community requests.

  • Yes. If you're on semaglutide or tirzepatide alone, PinPal works as a focused single-peptide tracker with the best reconstitution calculator on the market. The multi-peptide architecture is there when and if you need it.

  • Your protocol log lives in an encrypted database tied only to your account. We do not sell, share, or mine your data. We do not serve ads. Apple and Google sign-in are supported for passwordless auth.

  • Submitted to the App Store. We'll email everyone on the waitlist the moment review clears.

  • iOS first. Android is on the roadmap after we've validated the experience on iOS and shipped the first set of wearable integrations.

  • A free tier covers one or two protocols plus the reconstitution calculator. A paid tier unlocks unlimited stacks, symptom intelligence, decay curves, and the provider share report. Final pricing will be announced at launch.
