Peptide Therapy Guide for GLP-1 Users (May 2026)
Honest guides to the five peptides most commonly stacked with semaglutide and tirzepatide. Pricing, evidence, dosing, and the red flags consumer-marketing usually leaves out.
Regulatory context as of May 2026
None of the peptides on this site are FDA-approved for the off-label uses consumers commonly chase. Several were removed from the FDA Category 2 restricted list in April 2026 and are now eligible for patient-specific 503A compounding with a valid prescription. A PCAC review on July 23-24, 2026 is expected to formalize the status of BPC-157, TB-500, and others. Use only via licensed telehealth with physician oversight — gray-market "research peptide" sales are illegal for human use and carry sourcing/contamination risks.
