A TRACKER, NOT A PHARMACY

Peptide Stack does not sell, source, or recommend suppliers, and it is not a medical device. It records what you already do and helps you read the pattern. Always consult a licensed medical professional before starting, stopping, or changing any protocol.

Six tabs, one workflow

Built for the way you actually run a protocol.01

Peptide Stack pairs disciplined tracking with an AI second opinion. Everything you log lives on your device, syncs through your iCloud, and stays out of anyone else's database.

TODAY

Every dose, on time

Wake up to today's schedule. Tap to log a dose, snooze, or skip. Local notifications keep you honest.

JOURNAL

Photos, body data, notes

Markdown journal with photo attachments, weight, sleep, mood. Side-by-side comparisons over time.

LIBRARY

100+ compounds, demystified

Curated reference for BPC-157, TB-500, GHK-Cu, Semaglutide, Tirzepatide and more. Mechanism, half-life, common protocols.

CALCULATOR

Reconstitution math, solved

Vial size, BAC water, target dose. The calculator hands you the exact insulin-syringe units to draw.

AI ANALYSIS

Read your protocol like a coach

Claude reviews your stack against your log. Surfaces synergies, conflicts, and what to try next. Premium.

CALENDAR

Months at a glance

Dots for logged doses, journals, weight check-ins. Tap any day to scrub back through your timeline.

FAQ

Answered honestly.04
Does Peptide Stack sell peptides?

No. Peptide Stack is a tracking and analysis tool, not a pharmacy or a research-chemical vendor. We do not sell, source, or recommend suppliers.

Is my data private?

Everything you log lives on your device and syncs only through your personal iCloud account. We do not run a backend database of user logs, and no account is required to use the app.

What does the free version include?

Dose logging, the journal, the reconstitution calculator, the monthly calendar view, and a preview of the compound library. AI protocol analysis and the full library are premium.

How does the AI analysis work?

When you ask for it, a redacted summary of your active stack and schedule goes to Claude, which returns a structured review: what looks synergistic, what looks like a conflict, and what to consider next. It never runs on its own.

Can I get a refund?

All purchases are managed by Apple, so refund requests go through reportaproblem.apple.com. Apple typically honours reasonable requests within 14 days of purchase, but the decision is theirs.

Does it sync across iPhone and iPad?

Yes, through your iCloud account. Sign in to the same Apple ID on both devices and your stack, journal, and history follow you. The app falls back to a local-only store if iCloud is off.

Is there an Android version?

Not yet. Peptide Stack is iOS-only for now, iPhone and iPad on iOS 17 or later. Android is on the roadmap.

Ready to run a smarter protocol?

Set up your stack in two minutes and let the data speak. Free to try, premium when you need the deeper analysis. iPhone and iPad, iOS 17 or later, iCloud sync, no account required.
