FDA warning letters, closures, lawsuits and regulator alerts involving research-peptide sellers. In 2026 the FDA treated calculators, dosing guides and bacteriostatic water sold "for reconstitution" as evidence that "research use only" products were meant for people.

  1. HHS / FDA · Policy proposalReported

    Compounding pharmacies (not RUO web sellers)

    HHS and FDA sent an "interim access policy" to the White House that would let pharmacies compound BPC-157, TB-500, KPV, MOTS-c, Epitalon and Semax under enforcement discretion. It covers pharmacies, not research-use-only websites, and does not cover retatrutide or tirzepatide. Not final.
