My Pep Calc

What we built

My Pep Calc is a multi-compound injection tracker for people running peptide stacks, GLP-1 protocols, and longevity regimens. Reconstitution calculator, site rotation tracker, half-life chart, dose log, and an AI Protocol Coach — all in one place.

We built it because tracking a five-compound peptide stack with a notes app is a math error waiting to happen. Every compound you add makes the protocol geometrically harder. The tools most people were using stayed linear.

Our positioning

My Pep Calc is the neutral, compliance-safe tracking layer on top of the peptide, GLP-1, and compounding ecosystem. We are not a provider. Not a pharmacy. Not a vendor.

That positioning matters. Every other player in the space — compounding pharmacies, longevity clinics, telehealth operators — benefits from our existence. Patients who track carefully are safer patients, better customers, and more informed partners in their own care. We're the tool that makes the whole ecosystem work better.

Compliance as a feature

We don't make medical claims. Every screen, every email, and every AI response is written with that constraint built in. In an environment where Meta and the FDA are hammering GLP-1 and peptide marketing, "we are a tracking tool" is not a hedge — it's a moat.

Who built it

My Pep Calc was founded in Irvine, CA by a solo builder with 6+ years of experience shipping consumer health and SaaS products. The same codebase ethos that built prior products: move fast, stay clean, ship revenue before raising money.

We are a small team right now. That's intentional — the goal is product quality and customer trust before headcount.

Wave 1 personas

We launched for two audiences first: peptide biohackers (Marcus) and GLP-1 users who have moved past the beginner phase (Rachel). These are the highest-pain, most-research-literate segments in the market — people who already manage complex protocols and will actually use a serious tracking tool.

Longevity stackers (David) come next. TRT/HRT expansion follows.

The Founders deal

We sold the first 500 slots at $149 lifetime access before charging monthly. Those founders shaped the product and they'll always have direct access to the founding team.
