Thymogen (also marketed as Thymagen) is a synthetic dipeptide, L-Glu-L-Trp (Glu-Trp), originally isolated by the Khavinson group from the calf-thymus polypeptide complex Thymalin and then synthesized. It is registered as a pharmaceutical in Russia for immunocorrection (nasal drops / IM injection). Not FDA-approved in the US; research-use only.

How are Thymogen 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 base is single-lab (Khavinson and collaborators). A 12-month rat study (Anisimov, Khavinson, Morozov, Biogerontology 2000) reported extended maximum lifespan and reduced spontaneous tumor incidence. Russian clinical reports claim benefit in acute/chronic respiratory infections and post-surgical immunodeficiency; these have not been independently reproduced in Western RCTs.
