Who built this
I spent a decade building AI.
Then I aimed the same engineering at the body.
Men get two kinds of health advice online: bro-science from a forum, or a sterile telehealth funnel that just wants the sale. Neither tells you what to actually take, at what dose, from where, for your goal. So I built the thing I wanted myself.

Why this exists
I treat the body like any system I’ve ever built. Define the goal. Pick the inputs with the best evidence. Tailor the dose to the person. Measure. Adjust.
Peptide Engineering is exactly that, made legible: tell it your goal and your situation, and it returns a real protocol — the compounds, the doses, the timing, the bloods to watch, and where to get each one.
I don’t sell peptides. I curate the protocol and point you to the route that fits — a research-grade source or a licensed prescription — and I’m honest about the trade-offs of each. That’s the whole company.
How I build it
Engineer’s bias
Evidence over hype. Where the data is strong I lean in; where it’s thin, I say so out loud. No miracle language.
Curated, not sold
I hold no inventory and run no upsell. The recommendation is the product — the compounds, the doses, the sequence.
Two routes, your call
Every protocol shows both paths side by side — a vetted research source and a licensed prescription route. You decide.
No clinical theatre
Built for men who want the answer, not a waiting room. Direct, technical, and a little blunt — on purpose.
The background
Ten-plus years in AI and software, building products across machine learning, health and commerce. I’m not a doctor and I don’t pretend to be — I’m an operator who got obsessive about doing this properly, for himself first. Everything here is reference and curation, not medical advice.
