FAQ

What is the amino acid sequence of Testagen?
Testagen is a synthetic tetrapeptide with the reported sequence Lys-Glu-Asp-Gly (KEDG) — a man-made chain of four amino acids: lysine, glutamic acid, aspartic acid, and glycine.
How do I calculate Testagen reconstitution concentration?
Divide the vial's peptide mass (mg) by the volume of bacteriostatic water added (mL). Example: 20 mg in 3 mL gives ~6.7 mg/mL; 20 mg in 10 mL gives 2 mg/mL.
Is Testagen FDA-approved or listed on the WADA Prohibited List?
Testagen is not FDA-approved for any use. It is not named on the WADA Prohibited List but may fall under peptide hormone or metabolic modulator rules; athletes must verify current status with the relevant authority.
