Powered by ClaudeNo hunting through notes. No guessing what's next. Your active protocol, dose countdown, and quick-log are right there the moment you launch.
Stop calculating BAC water by hand or eyeballing the syringe. Pinned does the math precisely — for a single peptide or a full multi-peptide stack — and shows you exactly which line on the syringe to draw to.
A reference built into the app. From mechanism of action to cycling strategy — plus curated multi-peptide stacks you can load into the calculator with a single tap.
Generic peptide advice is everywhere. Yours isn't. Pinned Coach knows your protocols, dose history, and vials — so every answer is grounded in what you're actually running.
Every dose logged. Every vial tracked. Stability countdowns, adherence percentages, streak history — exactly what you need to actually run a protocol like a professional.
Early access users have logged tens of thousands of doses. Here's what they're saying.
Replaced three apps and a spreadsheet on day one. The reverse calculator alone is worth it — finally know exactly how much BAC water to add without doing it on paper.
The Coach actually knows what I'm running. Asked it about timing my Ipa around training, and it referenced the exact doses I'd logged that week. No other tool does this.
The vial countdown is the killer feature for me. I used to lose track of when I mixed something — now I get a heads-up before stability drops. Tiny detail, huge difference.
Short answers. If you have something else, email hello@pinned.fit.
Yes. Core features — tracking, calculator, library, vial inventory — are completely free, with no subscription. AI Coach has a generous free tier with optional upgrade for unlimited usage.
Both. Native App Store and Play Store builds are in private beta — join the waitlist to get early access.
Yes. Your protocols, dose history, and vials are stored in your account — encrypted in transit and at rest. We never sell or share your data with third parties. You can export everything as JSON at any time.
The reconstitution math is exact: dose ÷ concentration, with concentration derived from peptide mass and BAC water volume. We then snap to the nearest U-100 unit mark for the syringe size you've selected. Forward and reverse modes use the same formula in different directions — there's no fudge factor.
No. Pinned Coach is an educational tool only. It surfaces research-backed information about your stack, but it can't replace a qualified healthcare provider. Always consult a professional before starting, modifying, or stopping any peptide.
Yes. Pick from our pre-built stacks, customize one, or build from scratch in the Calculator. Setup takes under 2 minutes and the Coach can help you migrate from a spreadsheet if you have one.
Set up your first protocol in under 2 minutes. Available on iPhone and Android.
