What researchers mean by TRH
TRH (also called Thyrotropin-releasing hormone, Protirelin) appears in research-chemical and laboratory-supply catalogs under the category “Reproductive, tanning & sexual-health research”. Published evidence quality varies widely by compound. PurityWatch pages are educational transparency tools, not instructions for human use.
Laboratory & catalog context
Vendors often stock TRH alongside research peptides. Transparent sellers publish COAs, avoid therapeutic claims, and state research-use-only policies. Use PurityWatch to compare claimed purity, lab uploads, and trust signals — PurityWatch does not sell compounds.
