What is Testagen?

Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Leu) from the Khavinson programme targeting testicular tissue. Studied for Leydig cell gene expression normalisation, testosterone biosynthesis pathway modulation, and age-related androgen decline models. Research use only.

Research Applications

Leydig Cell Biology

Testosterone biosynthesis, StAR protein expression, steroidogenesis

Testicular Geroprotection

Age-related Leydig cell atrophy, late-onset hypogonadism models

Spermatogenesis Research

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2 mL bacteriostatic water to the lyophilized vial and swirl gently until clear. Dissolves within 1 minute.
How should this peptide be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks.
What purity is this QSC compound and how is it verified?
Testagen is primarily studied for age-related Leydig cell decline and the late-onset hypogonadism model. Research from the Khavinson institute suggests it normalises steroidogenic gene expression in testicular tissue as a geroprotective intervention.
