The peptide pathway — three tiers, three risk profiles.

FDA-approved (Semaglutide, Tirzepatide) vs telehealth-prescribed compounded vs research-grey. The peptide category audited without supplement-industry spin. The honest framework for what works, what is unproven, what we will not write a buying guide for.

Cover Story · Mens · Reported

Peptides, honestly.

GLP-1s (Semaglutide, Tirzepatide) have the strongest weight-loss data ever produced by any pharmacological class — 14.9% to 20.9% loss in placebo-controlled trials. Below that tier is a long tail of "research peptides" with promising animal data and minimal human evidence. We do not write buying guides for the third tier.
