GLP-1 / Weight Loss Agonists
Semaglutide
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.
Semaglutide is an FDA-approved GLP-1 receptor agonist originally developed for type 2 diabetes that has proven remarkably effective for weight loss. Clinical trials show average 15–20% body weight reduction. It is marketed as Ozempic (diabetes) and Wegovy (weight management).

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
