What is Testagen?

Endocrine/reproductive bioregulator (Khavinson peptide).

How Testagen works

Khavinson bioregulator peptide reported to support the reproductive/hormonal system via organ-specific gene-expression modulation. Short half-life; epigenetic-style effects.

Benefits & uses

Reproductive/hormonal-system support (reported)
Anti-aging interest
Organ-specific bioregulation

Common uses: Hormonal/reproductive support, anti-aging protocols.

Testagen dosage

Typical dose: Typical: 100–200 mcg/day SubQ or IM, in 10–20 day courses (repeated 2–3×/year). Endocrine/reproductive bioregulator.

Preparation & storage

Preparation: Mix a 20 mg vial with 4 mL bac water → 5 mg/mL. A 200 mcg dose = 0.04 mL = 4 units.
Reconstitution: Reconstitute a 20 mg vial with 4 mL BAC water → 5 mg/mL. A 200 mcg dose = 0.04 mL = 4 units on a U-100 syringe (tiny dose — a more dilute recon can help accuracy).
