What it is

Tesamorelin is a stabilized analogue of growth-hormone-releasing hormone used in research of the somatotropic axis.

Pathway Diagram

Mechanism of Action

CRL · MOA-01

Binds GHRH receptors on pituitary somatotrophs, stimulating endogenous growth-hormone pulsatility under physiological feedback.

  1. Step 01
    Receptor Binding

    Peptide engages target receptor with high affinity.

  2. Step 02
    Signal Cascade

    Downstream intracellular pathways activate.

  3. Step 03
    Cellular Response

    Gene expression and protein synthesis shift.

  4. Step 04
    Observed Outcome

    Measurable change in the studied biomarker.

Research highlights

Stabilized GHRH analogue with preserved endogenous pulsatility.
FDA-approved for HIV-associated lipodystrophy — robust visceral fat reduction.
Reduces liver fat in NAFLD research populations.
Does not bypass somatotropic feedback regulation.

Case studies

Clinical26 weeks

Visceral adipose reduction in HIV lipodystrophy

Cohort: 412 HIV+ adults

Phase 3 RCT of tesamorelin 2 mg/day on visceral adipose tissue (VAT) measured by CT.

Outcome

−15.2% VAT vs. +5.0% placebo with concurrent IGF-1 normalization.

Clinical6 months

Hepatic fat content

Cohort: 50 HIV+ adults with NAFLD

Randomized study using MRS quantification of hepatic and visceral fat.

Outcome

Significant reduction in liver fat fraction and VAT vs. placebo.

Clinical12 weeks

Metabolic safety in T2D

Cohort: 53 adults with T2D

Assessed glycemic safety of tesamorelin in patients with established T2D.

Outcome

Transient IGF-1 rise without sustained glycemic deterioration.
