See your levels over time.

Stackr uses each peptide's half-life and your logged doses to chart roughly what's active. These are estimates, not lab results.

  • Half-life for each peptide
  • 1W, 2W and 1M views
  • Dose markers on the chart
  • Active level for every peptide

Questions:

What is Stackr?
Stackr is a peptide tracker for iPhone. You log every dose, vial, and side effect in one place, with smart reminders and per-peptide level charts. It is built for people running real protocols.
What peptides does Stackr support?
Over 100 compounds and counting. Stackr ships with a curated library covering GLP-1s like semaglutide and tirzepatide, growth-hormone secretagogues like CJC-1295/Ipamorelin, healing peptides like BPC-157 and TB-500, NAD+, nootropic and bioregulator peptides, oral peptides, topicals, and many more.
Does Stackr handle non-injectable peptides?
Yes. Injectable, oral, sublingual, topical, and nasal forms are all first-class. The reminder, dose-tracking, and side-effect flow adapts to whatever form factor you choose for each compound.
Is Stackr a medical device?
No. Stackr is a personal tracking tool. It does not diagnose, treat, or prevent any condition, and nothing in the app is medical advice. Always consult a licensed clinician before starting, changing, or stopping any protocol.
Is my data private?
Your data is yours. We do not sell it, share it with advertisers, or use it to train AI models. Your peptides, doses, and supplies sync to your private Stackr account so they're available across your devices, encrypted in transit.
Is there an Android version?
Not yet. Stackr is iPhone-only today. An Android version is coming soon.
