Tesamorelin

Updated April 28, 2026

Primary Benefits:

  • Reduces visceral abdominal fat (especially in HIV-associated lipodystrophy)
  • Improves body composition and muscle tone
  • Enhances metabolism and energy regulation
  • May support cognitive health and neuroprotection
  • Stimulates growth hormone release without significant impact on cortisol or glucose

Mechanism of Action:
Tesamorelin is a synthetic analog of Growth Hormone Releasing Hormone (GHRH), designed to bind to and activate GHRH receptors in the pituitary gland. This stimulates the natural release of growth hormone (GH), which in turn promotes lipolysis (fat breakdown), lean muscle development, and improved metabolic activity—particularly targeting visceral fat deposits. Tesamorelin is FDA-approved for reducing excess abdominal fat in HIV patients with lipodystrophy, but its benefits extend to general body recomposition and anti-aging protocols.

Dosing & Protocol
Subcutaneous (SQ) Injection:

  • Reconstitution:
     2 mg vial → 1.0 ml bacteriostatic water
     (= 1 mg per 0.5 ml or 50 units)
  • Daily Dose:
     • 1 mg (50 units) per day
  • Cycle:
     • 6 days on / 1 day off
     • 4-week cycle = 10 vials
     • Repeat for 4 to 24 weeks based on goals
  • Timing:
     Take before bed, at least 90 minutes after your last meal.

Potential Side Effects:

  • Mild injection site irritation
  • Temporary water retention or bloating
  • Tingling or numbness in extremities (rare)
  • Elevated IGF-1 levels if overdosed
  • Headache, joint discomfort, or flushing (infrequent)

Common Stacks:

  • With Ipamorelin: synergistic GH release
  • With 5-Amino-1MQ: enhanced fat-burning and energy metabolism
  • With AOD-9604: complementary visceral fat reduction
  • With GHRH peptides like Sermorelin for longer-term growth hormone optimization

Notes:

  • Best results seen with consistent use over 12–24 weeks
  • Visceral fat loss typically begins to show after 4 weeks of regular use
  • Tesamorelin does not suppress natural GH production or testosterone levels
  • Store reconstituted peptide in the refrigerator and use within 45 days unless the product label or protocol says otherwise
