Thesamorelin is a synthetic analog of the hormone GHRH.

Tesamorelin — a detailed review of the peptide

Tesamorelin is a synthetic ghrelin-releasing hormone (GHRH) analogapproved by the FDA for the treatment of lipodystrophy in HIV-infected patients. , but it is also being investigated in the context of anti-aging therapy, fat burning and recovery.


1. Mechanism of action

Tesamorelin acts through the hypothalamic-pituitary axis:

  • Binds to GHRH receptors in the pituitary gland.
  • Stimulates the release of growth hormone (GH).
  • GH enhances the synthesis of IGF-1 in the liver, which leads to:
    • – Acceleration of lipolysis (breakdown of fat, especially visceral).
    • 🏋️ Improve muscle tone.
    • Нейро Neuroprotection and cognitive support.

Difference from other GHRPs (for example, GHRP-2/6):

  • Thesamorelin does not directly affect ghrelin receptors, so it does not cause severe hunger.
  • It gives a more physiological release of GH (closer to the natural pulsation).

2. Main effects

① Visceral fat reduction (main application)

  • Reduces the volume of abdominal fat by 15-20% in 3-6 months (studies in HIV patients).
  • It does not affect subcutaneous fat as much as visceral fat.

, Anti-age effects

  • Improves skin condition (increases collagen synthesis).
  • Supports bone density.
  • May slow down sarcopenia (muscle loss with age).

, Cognitive benefits

  • Potentially protects against neurodegeneration (Alzheimer’s disease).
  • Improves sleep quality (by normalizing GH secretion).

④ Sports application

  • Minor anabolic effect (less pronounced than that of IPA/The GRF mod).
  • Faster recovery from injuries.

3. Application Protocols

🔹 Medical dosages (for lipodystrophy)

  • 2 mg subcutaneously once a day (standard regimen).
  • Course: 6-12 months.

🔹 For fat burning/anti-aging therapy

  • 1-2 mg / day (in the evening or in the morning on an empty stomach).
  • Optimal course: 3-6 months.

Комбинации Combinations with other peptides

  • + CJC-1295 (without DAC) – increased GH emission.
  • + Ipamorelin -synergy without prolactin growth.

4. Side effects

  • Hyperglycemia (GH reduces insulin sensitivity).
  • Edema/tunnel syndrome (fluid retention).
  • Headaches (rare).
  • Activation of latent tumors (contraindicated in oncology).

Important: Monitor blood sugar and IGF-1 levels during the course.

ThesamorelinReducing visceral fatNoLow
GHRP-6Powerful GH release + AppetiteYesModerate
IpamorelinPure GH-stimulus without hungerNoLow
CJC-1295Prolonged GH secretionNoLow

6. Withdrawal

Tesamorelin is the best choice for:
Reducing visceral fat (especially in patients with metabolic disorders).
Anti-aging therapy (without sudden GH spikes).
Safe course (less side effects than GHRP-2/6).

Recommendations:

  • Start with 1 mg / day, control IGF-1.
  • Combine with diet and exercise for maximum fat burning.
  • It is contraindicated for tumors, pregnancy, and diabetes.
