Core — the one essential

One pen, one purpose. The single peptide we’d hand a friend who wants to start today with the least possible fuss. Lowest price, easiest first step, and enough to feel what peptides can do.

Repair — the upgrade

The Core peptide plus the support pens that make it work harder. Most people land here: the results come faster and the pens are matched so you never have to figure out what goes with what.

Regen — the full system

Every pen we’d want for the goal, in one box. Bigger results, faster, with the whole lineup pulling together — and a better price than buying the pens one at a time.

Stacking, made easy

Every pen in a stack is its own Smart Pen with its own dial, and the Human 2.0 app keeps the whole schedule straight. Open the stack page to see exactly what’s in the box, what each pen does, and which one to press first.
