Testagen is a synthetic tetrapeptide (Lys-Glu-Asp-Gly / KEDG) from the Khavinson bioregulator series, claimed to target testicular tissue. Not FDA-approved. Evidence base is extremely thin, with essentially no independently replicated or peer-reviewed support for the advertised reproductive or endocrine benefits in humans.

How are Testagen prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
Evidence is extremely limited. Fedoreyeva et al. (Biochemistry [Moscow], 2011; PMID 22117547) — from Khavinson-group collaborators — showed that fluorescently labeled Lys-Glu-Asp-Gly (testagen) penetrated HeLa-cell cytoplasm and nucleus and bound CAG-containing deoxyribooligonucleotides in vitro. No replicated Leydig-cell, animal, or human clinical-trial data has been published in indexed peer-reviewed literature. Reproductive or steroidogenic benefits in humans have not been demonstrated.
