Research profile
Testagen research profile
Testagen is the name used for the synthetic tetrapeptide Lys-Glu-Asp-Gly (KEDG), listed among the short peptides of V. Kh. Khavinson's group. Compared with Pinealon or Vesugen, very little peer-reviewed work on this sequence has been published.

Published research
- Listed as KEDG (Testagen) among the group's short peptides in a review of peptide regulation of gene expression (Khavinson, Lin'kova & Tarnovskaya, Bull Exp Biol Med, 2016).
- A Russian reference text by Khavinson and Ryzhak describes organotypic testis explants from young and old rats and a radiation-induced aging model in male rats for a short-peptide preparation named Testagen; it does not state the sequence.
- Note: peer-reviewed literature on this sequence is limited and comes mostly from one research group.
Frequently asked questions
What is the sequence of Testagen?
Lys-Glu-Asp-Gly (KEDG), a tetrapeptide with a calculated molecular weight of about 447.4 g/mol.
How does Testagen differ from Epitalon?
Epitalon is Ala-Glu-Asp-Gly (AEDG). Testagen has lysine in place of alanine at the first position (KEDG).
How do I verify my lot?
Scan the QR code on the vial. It opens the certificate of analysis for that lot, with HPLC purity and the mass spectrometry identity result.
