Testagen (20 mg Vial) Dosage Protocol

Testagen (Lys-Glu-Asp-Gly) is a synthetic tetrapeptide bioregulator targeting testicular tissue, studied in Russian protocols for male reproductive support, testosterone axis modulation, and age-related decline.

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Standard / Gradual Approach (3 mL = ~6.67 mg/mL)

WeekDaily Dose (mcg)Units (per injection) (mL)
Weeks 1–2100 mcg (0.1 mg)1.5 units (0.015 mL)
Weeks 3–4150 mcg (0.15 mg)2.25 units (0.0225 mL)
Weeks 5–8200 mcg (0.2 mg)3 units (0.03 mL)
Weeks 9–12 (optional)250–300 mcg (0.25–0.3 mg)3.75–4.5 units (0.0375–0.045 mL)

Frequency: Inject once daily subcutaneously, consistent with preclinical study protocols. For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.

Reconstitution Steps

  1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl/roll until dissolved (do not shake).
  4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Supplies Needed

Plan based on an 8–16 week daily protocol with gradual titration.

16 weeks (2 vials): 6 mL → 1 × 10 mL bottle
Alcohol SwabsPer week: 14 swabs (2/day)

Protocol Overview

The hypothesized gene-expression mechanism produces effects that persist months after the cycle ends, supporting the cycled rather than continuous approach. Evidence base is primarily Russian gerontology and clinical research; peer-reviewed Western data is limited.

Storage Instructions

StateTemperatureDuration
Lyophilized−20°C (−4°F)Up to 24 months, dry & dark
Reconstituted2–8°C (35–46°F)Up to 30 days, protect from light

Important Notes

⚠ Research Use Only. Khavinson-class peptide bioregulator; most evidence is from Russian gerontology research.

How This Works

Testagen is a Khavinson-class peptide bioregulator hypothesized to modulate gene expression in testicular tissue supporting spermatogenesis and Leydig cell function.
