The first tracker built for the post-Category-1 era · Peptides · GLP-1 · TRT · Longevity
Every compound you add multiplies what you track — site, timing, dose, frequency, cycle, half-life. The apps you’re using add it up in a straight line. That gap is why vials get ruined, sites get lumpy, and stacks stall. My Pep Calc closes it.

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.
My Pep Calc is geometric-complexity tooling for a geometric-complexity problem. Every compound on your stack shares one log shape, one rotation map, one half-life engine, one dose-correlation layer. Reconstitution math feeds the log. The log feeds the rotation map. The rotation map feeds the half-life chart. Nothing you track lives alone.
That calculator is one of 12 compounds My Pep Calc handles out of the box. Inside the app, the number it just produced auto-populates your dose log, updates your half-life chart, and assigns your next rotation site. This is what a single dashboard looks like.
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.
