Synthetic Peptide for Testicular Bioregulator Research

Technical Overview

Testagen 20mg is a synthetic peptide compound developed for laboratory research involving testicular gene expression and short-peptide bioregulator activity, receptor interaction analysis, and controlled experimental investigation. In research settings, this peptide is commonly utilized for studying testicular cell signaling, hormone-related transcription factor activity, and related biochemical mechanisms. Testagen is a Khavinson-class short-peptide bioregulator with the sequence L-Lys-L-Glu-L-Asp-L-Gly (KEDG), originally derived from analysis of testicular tissue extracts by Prof. Vladimir Khavinson's research group. Short peptides in this class are hypothesized to interact with DNA in a sequence-specific manner, modulating gene expression within their tissue of origin. Testagen shares three of four residues with Livagen, substituting glycine for alanine at the C-terminus, which is associated with testicular-tissue specificity within the Khavinson framework.

Frequently Asked Questions

Is TESTAGEN third-party tested?

Yes. Every lot is independently third-party tested for identity and purity — ≥99% by HPLC and mass spectrometry — with a lot-matched Certificate of Analysis available to download on this page.

Can I see the Certificate of Analysis before buying?

Yes. A lot-matched COA is available on this product page and in our COA library before purchase, documenting identity, purity, and full analytical results.

What does 'Research Use Only' mean?

This product is supplied strictly for laboratory and research use only (RUO). It is not a drug, food, supplement, or cosmetic, is not approved by the FDA, and is not intended to diagnose, treat, cure, or prevent any disease, or for human or veterinary consumption.

How is it shipped and stored?

Orders placed before 12pm CT typically ship the same business day from our U.S. facility with tracking. Store the lyophilized material at -20°C, protected from light and moisture.
