Quick Answer
Tesamorelin is FDA-approved specifically for reducing visceral fat in HIV lipodystrophy. Shows significant belly fat reduction.
Evidence Level
FDA Approved
Typical Dose
2 mg daily subcutaneous
Results Timeline
Significant visceral fat reduction over 3-6 months
FDA Status
FDA Approved
How Tesamorelin Works for Fat Loss
GHRH analog increases GH which preferentially targets abdominal fat stores.
About Fat Loss
Reduction of body fat while preserving lean muscle mass.
Research Evidence
FDA approved based on trials showing 15-20% reduction in visceral adipose tissue over 26 weeks. March 2025: FDA approved new F8 formulation (Egrifta WR) with weekly reconstitution, reducing patient burden. CROI 2025 data highlighted limitations of BMI for cardiovascular risk assessment in HIV patients.
Dosing for Fat Loss
Recommended Dose
2 mg daily subcutaneous
Frequency
Once daily
Administration
Subcutaneous injection
Duration
Indefinite for approved indication
Note: FDA-approved dose is 2 mg (original) or 1.28 mg (F8/Egrifta WR formulation). Inject subcutaneously in abdomen. F8 requires weekly reconstitution vs daily.

Other Peptides for Fat Loss
These peptides are also researched for fat loss.
Ipamorelin
Clinical TrialsA selective growth hormone secretagogue that stimulates GH release without significantly affecting cortisol or prolactin. Considered one of the safest GHRPs.
MK-677
Clinical TrialsAn orally active growth hormone secretagogue that mimics ghrelin. Although technically not a peptide, it is frequently discussed alongside GH peptides due to similar effects.
CJC-1295 (No DAC)
Clinical TrialsA synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates GH release from the pituitary. Often combined with a GHRP like Ipamorelin for synergistic effects.
GHRP-6
Clinical TrialsOne of the first synthetic GH secretagogues developed. Strongly stimulates GH release and significantly increases appetite through ghrelin receptor activation.
