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.
Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland extract Thymalin. The shortest immune-regulatory peptide known, Vilon modulates T-cell and NK-cell function, extends lifespan in animal models, and shows epigenetic anti-aging activity. It is one of the Khavinson peptide bioregulators.

Once daily
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
  • Immune system modulation and restoration
  • Lifespan extension (30–40% in animal studies)
  • T-cell and NK-cell activation
  • Epigenetic anti-aging activity
  • Reduces oxidative stress markers
  • Antioxidant gene upregulation
  • May prevent age-related immune senescence
  • Anti-tumor immune surveillance
Side Effects
  • Initial testosterone flare (intended)
  • Injection site reactions
  • Hot flashes (with chronic use)
  • Decreased libido (chronic dosing)
  • Excellent safety profile, decades of Russian clinical use
  • Rare: mild injection site reaction
  • Very rare: mild allergic reaction
