Dosage protocol · Growth Hormone & Performance
Tesamorelin 20 mg
Standard daily dose: 2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).
- Reconstitute: Add 3.0 mL bacteriostatic water per 20 mg vial → ~6.67 mg/mL concentration.
- Standard daily dose: 2 mg (2000 mcg) once daily subcutaneously (FDA-approved protocol).
- Easy measuring: At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.7 mcg on a U-100 insulin syringe.
- Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F); reconstituted: refrigerate and use within 7 days with bacteriostatic water.

How it works
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), the hypothalamic signal that tells the pituitary gland to release growth hormone.[1] Rather than replacing growth hormone directly, it works upstream, prompting the pituitary to produce more of it.
In the US, tesamorelin is marketed as the prescription drug EGRIFTA SV, with an FDA-approved indication limited to reducing excess abdominal fat in adults with HIV-associated lipodystrophy, a condition involving abnormal fat redistribution linked to HIV and antiretroviral therapy.[2] That approval is narrow: it does not cover general weight loss, bodybuilding, anti-aging, or cosmetic use, and the label states tesamorelin is not indicated for weight-loss management.
Benefits & side effects
The core evidence is a randomized trial published in the New England Journal of Medicine, which found tesamorelin reduced visceral adipose tissue in HIV-positive adults with abdominal fat accumulation compared with placebo — the data underlying FDA approval.[3] Imaging methods such as CT and MRI distinguished visceral fat from subcutaneous and liver fat, since a change in one compartment does not necessarily track with overall body weight.
Beyond the approved indication, trials in JAMA and The Lancet HIV examined tesamorelin's effect on liver fat in HIV-positive adults and reported reductions in hepatic fat.[4] These findings are promising but investigational; tesamorelin is not FDA-approved for fatty liver disease, and visceral-fat reductions have not been shown to persist after stopping treatment. Claims about muscle gain, performance, or anti-aging go well beyond what this evidence supports.
