Testagen
Also known as: Peptídeo testicular
Molecular Identifiers
Overview
Bioregulatory tetrapeptide developed by Professor Khavinson's group. Researched for its ability to regulate testicular function and modulate gene expression in Leydig and Sertoli cells.

~2-4 hours
Administration Route
Subcutaneous or intramuscular
Category
Hormonal Regulation
Mechanism of Action
- Regulation of testicular function via epigenetic modulation
- Modulation of gene expression in Leydig cells
- Influence on endogenous testosterone synthesis
- Interaction with DNA in the regulation of testis-specific genes
- Bioregulatory effect on spermatogenesis
