COA and RUO review policyOn November 3, 2026, the United States Pharmacopeia (USP) issued a public statement on the HHS enforcement discretion policy for six peptides (BPC-157, TB-500, others), stating it lacks essential quality safeguards: no USP-NF monographs, no reference standards, and no established names. Here is what USP said and why it matters for identity and purity testing.
On October 28, 2026, HHS filed a Federal Register notice announcing enforcement discretion for state-licensed pharmacies, federal facilities, and physicians compounding with certain peptides including BPC-157 and TB-500. Here is what the policy covers, what it does not, and the timeline ahead.
BPC-157, TB-500, and CJC-1295 are among the compounds facing new regulatory scrutiny in 2026. This research-use-only primer explains what changed, what remains available as RUO materials, and what documentation researchers should maintain.
Tendon repair research models involve distinct peptides targeting angiogenesis, actin dynamics, and matrix remodeling—compared here with RUO sourcing navigation.
Social channels amplify incretin peptide discussions; this article contrasts Reddit narratives with trial-published endpoints for research literacy.
Semaglutide, tirzepatide, and retatrutide represent single, dual, and triple incretin receptor agonism. This guide compares their mechanisms and published research context so laboratories can choose the right compound for a study.
