Testagen (20 mg Vial) Dosage Protocol
Testagen Dosage Chart
Testagen is dosed at 100 mcg–300 mcg daily via subcutaneous injection in educational protocols. A 20 mg vial reconstituted with bacteriostatic water yields about 6.67 mg/mL. This information is for research and educational use only.
Reconstitute: Add 3.0 mL bacteriostatic water → ~6.67 mg/mL concentration.
Typical daily range: 100–300 mcg once daily (gradual titration).
Easy measuring: At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.7 mcg on a U‑100 insulin syringe.
Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.
Testagen is a synthetic tetrapeptide with the sequence Lys‑Glu‑Asp‑Gly (KEDG), an anterior pituitary‑derived bioregulator studied for its role in modulating endocrine function, particularly the pituitary–gonadal axis[1][2]. Preclinical research indicates effects on thyroid hormone normalization and male reproductive hormone modulation[3][4]. This educational protocol presents a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.

Standard / Gradual Approach (3 mL = ~6.67 mg/mL)
Weeks 1–2
100 mcg (0.1 mg)
1.5 units (0.015 mL)
Weeks 3–4
150 mcg (0.15 mg)
2.25 units (0.0225 mL)
Weeks 5–8
200 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[3][4]. For ≤10‑unit (≤0.10 mL) administrations, consider 30‑ or 50‑unit insulin syringes for improved readability.
Reconstitution Steps
Draw 3.0 mL bacteriostatic water with a sterile syringe.
Inject slowly down the vial wall; avoid foaming.
Gently swirl/roll until dissolved (do not shake)[5].
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.
Peptide Vials (Testagen, 20 mg each):
8 weeks (~14 mg used) ≈ 1 vial
12 weeks (~25 mg used) ≈ 2 vials
16 weeks (~36 mg used) ≈ 2 vials
Insulin Syringes (30‑ or 50‑unit recommended for low‑volume accuracy):
Per week: 7 syringes (1/day)
8 weeks: 56 syringes
12 weeks: 84 syringes
16 weeks: 112 syringes
Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.
8 weeks (1 vial): 3 mL → 1 × 10 mL bottle
12 weeks (2 vials): 6 mL → 1 × 10 mL bottle
16 weeks (2 vials): 6 mL → 1 × 10 mL bottle
Alcohol Swabs: One for the vial stopper + one for the injection site each day.
Per week: 14 swabs (2/day)
8 weeks: 112 swabs → recommend 2 × 100‑count boxes
12 weeks: 168 swabs → recommend 2 × 100‑count boxes
16 weeks: 224 swabs → recommend 3 × 100‑count boxes
