Tell us about you and what you're working on. We map your situation to how the compounds actually work and hand back a tailored starting protocol from the Targeted Peptide Systems framework.
Where the dosing lives
Every dose in this Builder is drawn from Targeted Peptide Systems.
Already own the book? Look your compounds up as you go — the Builder tells you exactly which ones you need.
Prefer them right here? The Dosing Upgrade puts them in the app, labelled Low / Moderate / High and matched to your experience level.
Important This builder is an educational companion to the Targeted Peptide Systems book. Any dosing shown reflects the reference ranges published in that book and is not medical advice, diagnosis, or treatment. Many compounds referenced are research peptides not approved for these uses. Always consult a qualified healthcare professional before considering any protocol.

Before you start
The Protocol Builder is an educational companion to Targeted Peptide Systems. It maps what you tell it to how the compounds work — it does not provide medical advice, diagnosis, or treatment. Many compounds referenced are research peptides not approved for these uses.
