The first tracker built for the post-Category-1 era · Peptides · GLP-1 · TRT · Longevity
The 2-minute diagnostic tells you: are you tracking your protocol or tracking your intentions? Most people have a protocol in their head and a log that doesn't match it. Find out which one you have.

Stage 1 — Acute
“I just need to remember to inject on Sunday.”
One compound. Notes app. Weekly reminder. Works — for six weeks.
Stage 2 — Escalation
“Now I'm also running BPC-157 twice a day. The reconstitution math is wrecking my brain.”
Two compounds. Different schedules. Your Notes app is already failing.
Stage 3 — Chronic
“Five vials in the fridge, I don't remember which site I used Tuesday, and I think I ruined a tirzepatide vial.”
Four-plus compounds. Spreadsheet tabs. Google search for every vial. Nothing talks to anything else.
Stage 4 — Breaking Point
“I took a two-week break because I couldn't keep up.”
Compliance collapses. Results stall. You blame the compound. It wasn't the compound — it was the tracking.
You are somewhere on this timeline right now. Every compound you add moves you down it.
Protocol complexity scales geometrically — site × timing × dose × frequency × cycle × half-life, multiplying with every compound you add. Your tools scale linearly— a Notes app, a reminder, a spreadsheet row. The gap between geometric complexity and linear tools is where results die. That’s the mechanism. Fix the mechanism and the math, the sites, the stalls, the ruined vials — they all resolve at once.
Two personas. One product. Whatever your stack looks like, My Pep Calc tracks it.
Peptide stack
BPC-157 twice a day. TB-500 on Sundays. CJC/Ipa before bed. Five vials, three half-lives, bilateral rotation. You've been tracking in Notes. You know it's broken.

You've dropped the weight. Now you want to hold the muscle, rotate the sites, and bridge the stack with compounds your GLP-1 app was never built to handle. That's the next phase. This is the tracker for it.
See features for GLP-1 bridging →By design
We don't prescribe. We don't fulfill. Your doctor and pharmacy stay exactly where they are.
We never sell or ship the compounds you track. We just make tracking them coherent.
Every feature is about logging your behavior, not promising an outcome. This is why we exist during the regulatory tightening other apps can't survive.
Switzerland is the position. Compounding pharmacies, clinics, and telehealth operators all refer users to My Pep Calc precisely because we never compete with them.
