Buy Testagen Europe. Testicular bioregulator tetrapeptide for reproductive research. ≥99% purity. Fast EU delivery.
What is Testagen?
Testagen is a synthetic bioregulatory tetrapeptide developed as part of Professor Vladimir Khavinson’s bioregulatory peptide programme at the St. Petersburg Institute of Bioregulation and Gerontology. Testagen specifically targets testicular tissue, modulating gene expression in Leydig and Sertoli cells to support reproductive endocrine function, steroidogenesis, and spermatogenesis. For published research, see PubMed studies on Testagen{:target=“_blank” rel=“noopener”}.
Testagen represents an important research tool for studying testicular bioregulation, male reproductive ageing, and the effects of short peptides on gonadal function.
Best-Peptides supplies research-grade Testagen with guaranteed ≥99% purity and full analytical documentation.

FAQ
Testagen is a testicular bioregulatory tetrapeptide studied for its effects on testicular tissue function. Research focuses on its ability to modulate Leydig cell gene expression, support spermatogenesis, and regulate reproductive endocrine pathways.
Testagen acts as a tissue-specific bioregulator targeting testicular cells, particularly Leydig and Sertoli cells. It modulates gene expression patterns involved in testosterone synthesis and spermatogenesis.
Testagen interacts with chromatin in testicular cells, modulating the expression of genes involved in steroidogenesis, germ cell development, and reproductive endocrine function.
Store lyophilised Testagen at -20°C for long-term stability. Once reconstituted, keep at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles.
Our Testagen is ≥99% pure as verified by HPLC. Each batch includes a Certificate of Analysis with purity data and mass spectrometry identity confirmation.
Yes, Testagen is often studied in combination with other Khavinson bioregulatory peptides. Researchers should consider complementary endocrine pathways when designing multi-peptide studies.
Reconstitute in sterile bacteriostatic water. Add solvent slowly along the vial wall and gently swirl to dissolve. Testagen is highly soluble and dissolves readily in aqueous solution.
Testagen is available in 20mg vials (10 × 20mg per pack) for research applications.
