Tesamorelin FAQ: common questions answered
A peptide approved for deep abdominal fat in adults with HIV lipodystrophy.
Also called: TH9507, TH-9507, Egrifta, Egrifta SV, Egrifta WR.
GHRH analogues · Growth hormone-releasing hormone receptor agonist · Evidence: Approved drug.
- Is Tesamorelin FDA-approved? Yes: Egrifta (excess abdominal fat in adults with HIV lipodystrophy; original formulation now discontinued.); Egrifta SV (excess abdominal fat in adults with HIV lipodystrophy.); Egrifta WR (excess abdominal fat in adults with HIV lipodystrophy.). Not approved for weight-loss management.
- How do people take it? Under the skin, once daily. Source: drug label.
- What's the difference between Tesamorelin and Ipamorelin? Tesamorelin: a peptide approved for deep abdominal fat in adults with HIV lipodystrophy. Ipamorelin: an experimental peptide that triggers growth hormone release. Why people pair them: reported to add another GH-release signal for sleep, recovery or recomp. No controlled combination outcome trial was found.
- Can I take it with Ipamorelin? Reported to add another GH-release signal for sleep, recovery or recomp. No controlled combination outcome trial was found. Potential additive IGF-1, swelling and glucose effects; combined safety is unknown. Source: reported by users. Ask a doctor before combining anything.
- Is it banned in sport? Yes. It is banned in and out of competition (WADA 2026). Tesamorelin is named among GHRH analogues; the 2026 list remains applicable through December 31, 2026.
- How long does a mixed vial last? WR: room temperature (20–25°C); discard seven days after mixing. SV/original: use immediately; discard leftovers. Do not refrigerate or freeze any mixed formulation.
