RM-END / Endocrine and peptide-hormone analogs
Testagen
Also known as: KEDG peptide · Lys-Glu-Asp-Gly
Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.
What this is
Testagen is identified as Lys-Glu-Asp-Gly in the cited primary paper. The brand name should never stand alone without the sequence and terminal form.
Evidence position
Direct cell and molecular studies support Grade C. No qualifying human intervention record for the exact tetrapeptide was identified.
What the record does not establish
Cell entry and in-vitro DNA interaction do not establish a clinical outcome, route, dose or supplier-lot identity and purity.
