Overview
Testagen — Testes-research bioregulator peptide
What is Testagen?
Testagen is a short synthetic peptide from the Khavinson bioregulator family, studied in testicular-tissue and endocrine research models. It rounds out the family's tissue coverage in this catalogue alongside Epithalon, Pinealon, Cartalax, and Prostamax.
Why researchers choose it
Bioregulator research is comparative by nature — the family's interest lies in tissue-specificity, so having each member verified to the same standard matters for clean comparisons. Testagen's ultra-short sequence makes identity and purity verification straightforward and repeatable. REPRIME supplies a lyophilized 20 mg vial.
The REPRIME standard
Comparative research needs a constant: the quality bar. Every batch is independently HPLC-tested and released at ≥99% main-peak purity, with the batch COA published in the Certificates repository. The 20 mg lyophilized vial ships cold-chain in tamper-evident packaging with a unique REP-XXXX-XXXX-X code — one scan at first use confirms it is genuine. For laboratory and research use only; not for human consumption.
Storage
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
Research use only
For laboratory and research use only. Not for human or animal consumption.
