Peptide Therapy Guide

Safety questions dominate peptide therapy, and for good reason: most peptides discussed in this guide have no completed human safety database. This chapter consolidates the safety picture — common effects, route-specific risks, interactions, dose-dependent effects and what long-term data actually exists.

Peptides are signalling molecules, not nutrients. What they do depends almost entirely on which receptor they bind and how long they survive in the bloodstream. This chapter walks through the mechanisms behind the main peptide classes covered in this guide.
