Testagen- Summary
- Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
- Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Gly) developed by Professor Vladimir Khavinson, tissue-specific for the testes. It supports Leydig cell function, normalization of testosterone biosynthesis, and spermatogenic activity. Testagen is used in men's health protocols for age-related testosterone decline, male fertility support, and testicular anti-aging.

- Typical Dose
- 100 mcg
- 10 mg per day
- Frequency
- Single injection
- Daily for 10–30 days
- Key Benefits
- Rapid HPG axis restart after steroid use
- Single-injection PCT protocol possible
- Massively elevates LH and FSH via flare effect
- Restores endogenous testosterone faster than traditional PCT
- FDA-approved for established medical uses
- Supports endogenous testosterone synthesis via Leydig cell normalization
- Promotes spermatogenesis and sperm quality
- Anti-aging effects on testicular tissue
- May attenuate age-related testosterone decline
- Mechanistically distinct from TRT — does not suppress HPG axis
- Useful adjunct to Gonadorelin and Kisspeptin-10 in male hormonal protocols
- Supports male fertility without exogenous hormone replacement
- Side Effects
- Initial testosterone flare (intended)
- Injection site reactions
- Hot flashes (with chronic use)
- Decreased libido (chronic dosing)
- Generally well tolerated
- Mild injection site reactions
- No significant endocrine disruption reported at standard doses
