Testagen Research Overview
Testagen is a 4-amino-acid synthetic peptide (Lys-Glu-Asp-Gly) derived from the Khavinson short-peptide line of organ-specific bioregulators. It is the prostate/urogenital-tissue counterpart to other Khavinson tetrapeptides such as Epitalon (pineal) and Bronchogen (lung).

Molecular formula C₁₉H₃₄N₆O₉, molecular weight 490.5 g/mol, sequence Lys-Glu-Asp-Ser. Testagen is hypothesized to act at the transcriptional level in prostate and urogenital tissue, modulating expression of genes involved in epithelial proliferation, secretory function and androgen-axis regulation. Russian-language gerontology literature reports improvements in age-related prostate function markers at low repeated doses. Testagen is supplied as lyophilized powder and is classified in our catalog under peptide bioregulator for peptide bioregulator work. Recorded research categories for this compound include prostate and urogenital research, male reproductive and hormonal-axis studies, healthy-aging and male-longevity research, khavinson tetrapeptide bioregulator pharmacology. Handling notes: store at 2–8°c (refrigerator), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for Testagen: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions
What tissue does Testagen target?
In published Khavinson-group research, Testagen is the prostate/urogenital-tissue bioregulator of the short-peptide family — analogous to how Epitalon targets the pineal gland and Bronchogen targets bronchial epithelium.
Is Testagen androgenic?
No. Testagen is a 4-amino-acid peptide that modulates gene expression in prostate and urogenital tissue, rather than acting as an exogenous androgen. It is studied for tissue-specific regulatory effects, not steroid replacement.
Is your Testagen third-party tested?
Yes — every batch ships with HPLC verification at ≥99.0% purity, mass-spec identity confirmation and a batch-specific Certificate of Analysis.
What is Testagen studied for?
Testagen appears in laboratory research covering male hormonal research, testicular function studies, andrology. All references describe in-vitro and preclinical study models only.
Does Testagen include a Certificate of Analysis?
Yes. Each Testagen lot ships with a batch-specific third-party Certificate of Analysis reporting 99.0% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.
What form does Testagen arrive in?
Testagen is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
