Dragon Pharma Testagen 20mg Testicular Bioregulator Vial

Testagen 20 mg by Dragon Pharma is a cutting-edge testosterone-boosting bioregulator peptide specifically developed to stimulate natural testosterone production, improve Leydig cell function, and support male hormonal health. Originally researched in Russian military medicine, Testagen is recognized as one of the most effective short peptides for restoring testicular function and optimizing androgen levels without exogenous hormones.

What It Is

Testagen is a synthetic tetrapeptide bioregulator (Lys-Glu-Asp-Gly) that selectively targets testicular tissue and the hypothalamic-pituitary-gonadal axis. It belongs to the renowned Khavinson peptide family and works at the epigenetic level to normalize testosterone synthesis. Supplied as 20 mg lyophilized powder in a sterile vial.

How It Works

Testagen penetrates Leydig cells and modulates gene expression responsible for steroidogenesis and gonadotropin sensitivity. It upregulates enzymes involved in testosterone biosynthesis while enhancing LH/FSH receptor responsiveness. Clinical and user data consistently show significant increases in total and free testosterone within weeks.

Testagen 20mg Benefits

• Natural Testosterone Boost: Increases endogenous production without suppression
• Improved Libido & Energy: Restores drive, mood, and performance
• Leydig Cell Regeneration: Repairs testicular tissue damaged by AAS or age
• Faster HPTA Recovery: Accelerates natural testosterone rebound post-cycle
• Enhanced Spermatogenesis: Supports fertility and semen parameters
• Mood & Cognitive Support: Balances androgen-related brain function

Who It's For

Testagen is ideal for men over 30 experiencing natural testosterone decline, bodybuilders and athletes coming off heavy anabolic steroid cycles who want the fastest possible HPTA recovery, individuals with low libido, fatigue, poor recovery, or brain fog linked to suboptimal androgen levels, and anyone seeking a completely non-suppressive, research-backed way to optimize natural testosterone production and overall male vitality without using SERMs or hCG.

How to Use

Reconstitute the 20 mg vial with 2–3 ml of bacteriostatic water and gently swirl until fully dissolved. Standard protocol is 1–2 mg (0.1–0.2 ml) injected subcutaneously once daily, preferably in the morning to mimic natural testosterone rhythm. For post-cycle recovery, begin immediately after the last steroid dose and run 10–20 consecutive days; for age-related optimization or low-T support, one 10–20 day cycle every 8–12 weeks is sufficient. Most users report noticeable effects within 10–14 days and peak benefits after 3–6 weeks.

Stacking Suggestions

Testagen shines in PCT and long-term hormonal optimization stacks: combine with Clomid 25–50 mg or Nolvadex 20 mg daily for the ultimate pharmaceutical-grade recovery protocol; pair with hCG 500–1000 IU 2–3x/week during the first 2 weeks of PCT for even faster Leydig cell reactivation; stack with Pinealon and Ventfort for a complete Khavinson male rejuvenation program; or use alongside natural boosters like Tongkat Ali, Fadogia Agrestis, and Zinc for a fully non-suppressive testosterone optimization cycle.

Side Effects

Testagen is exceptionally well tolerated with an outstanding safety profile established over decades of clinical use. No estrogen conversion, no suppression of natural testosterone, and no androgenic side effects occur. The only occasionally reported effects are mild redness or itching at the injection site and, extremely rarely, temporary mild headache or slight increase in libido/aggression during the first few days as testosterone levels rise. No liver, kidney, or cardiovascular stress has ever been documented.

Post Cycle Therapy (PCT)

Not required — Testagen is one of the few compounds that actually helps restore the HPTA instead of suppressing it. It can be safely used during PCT to dramatically speed up natural testosterone recovery, or even during a steroid cycle as a bridge to maintain testicular function. Because it works through gene expression rather than hormonal feedback, Testagen never causes shutdown and is suitable for continuous or long-term use in men seeking permanent testosterone optimization.
