12 Peptides Covered

Peptide Therapy Guide 2026

The FDA is reclassifying peptides in 2026 — and the landscape is shifting fast. This guide covers every major therapeutic peptide: current FDA status, evidence-based benefits, side effect profiles, and where to find legitimate clinics.

2026 FDA Peptide Reclassification

In 2026, approximately 14 of 19 Category 2 peptides are returning to Category 1, making them available again through compounding pharmacies. This is the largest regulatory shift for peptide therapy since the original restrictions. Some peptides remain restricted — check the status badge on each peptide below.

Healing & Recovery

Peptides that promote tissue repair, reduce inflammation, and accelerate healing from injury.

BPC-157

Returning

Category 2 → returning to Category 1 (2026)

Body Protection Compound-157 is the most widely studied healing peptide. Promotes gut lining repair, accelerates tendon and ligament healing, and reduces inflammation.
