7 pieces tagged research-use-only.
- Where the line isWhat FDA reads on a website before it calls a research product a drugThe 'research use only' label is not what FDA reads. Its 2024 to 2026 warning letters spell out what is: claims, calculators, diluents sold alongside vials, and customer reviews. Here is the rule and the letters in their own words.
- Where the line isRetatrutide is investigational: what that status meansRetatrutide (LY3437943) is Eli Lilly's single-peptide agonist of the GIP, GLP-1 and glucagon receptors, with no FDA-approved product as of September 2026. What 'investigational' means, and why a research vial is not the trial drug.
- Sourcing and provenanceHow to vet a peptide vendor with documents, not with forumsA document-by-document checklist for judging a research peptide supplier: lot-specific certificates, identity as well as purity, net peptide content, a named manufacturer and a verifiable laboratory.
- Sourcing and provenanceCosmetic-grade vs research-grade peptidesWhat an INCI name is and who assigns it, what documents a cosmetic formulator needs from an ingredient supplier, and why a vial labelled research use only is not a cosmetic raw material.
- Where the line isBPC-157 in 2026: not banned, not approved, not compoundableThree separate questions get asked as one. BPC-157 is not a controlled substance, is not an FDA-approved drug, and has no lawful 503A compounding pathway. What the molecule is and where each answer comes from, dated.
- Where the line isAre peptides legal in the United States? A dated answer"Legal" hides seven different questions: controlled-substance status, who the law regulates, sale as research material, approval, compounding, import and sport. Each has a different answer and a different regulator. Here they are, dated.
- Where the line isCompounding pharmacy, outsourcing facility or research supplierA 503A pharmacy, a 503B outsourcing facility and a research supplier operate under three different sets of rules. What each one is, why a pharmacy cannot compound BPC-157 today, and why a research vial has no place in the other two chains.
