RM-END / Endocrine and peptide-hormone analogs

Thyrotropin-releasing hormone

Also known as: TRH · Thyroliberin · Protirelin

Human evidenceEvidence grade B: Human evidence

Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.

What this is

TRH is a three-residue amidated peptide produced from a larger precursor. It is distinct from longer TRH-associated peptides and synthetic analogs.

Evidence position

Direct human administration and endocrine-response measurements support Grade B.

What the record does not establish

Historical mechanistic studies do not establish current product approval, a safe research workflow, or the identity, concentration and microbiological quality of another sample.
