About Testagen

What it is
Testagen is a short synthetic peptide from the Khavinson family of tissue-specific "bioregulators" developed in St Petersburg, Russia. It is directed at the testes and has been studied in animals for effects on spermatogenesis and sex hormone production. Evidence outside Russian-language rodent work and small uncontrolled reports is limited.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
