Somatrogon (Ngenla) vs Tesamorelin
An educational, source-based comparison of Somatrogon (Ngenla) and Tesamorelin — how each peptide works, what it's researched for, and what to know before going deeper.
Long-acting recombinant human growth hormone for pediatric GH deficiency — weekly dosing.
A long-acting recombinant fusion protein of human growth hormone with three copies of the C-terminal peptide (CTP) of hCG beta-subunit, extending half-life and enabling once-weekly subcutaneous dosing instead of daily.
- Pediatric growth hormone deficiency
- • FDA-approved June 2023.
- • Same class warnings as daily GH (intracranial hypertension, glucose effects, scoliosis progression).
- • Injection-site reactions common.
A stabilized analog of growth hormone-releasing hormone (GHRH) that stimulates pulsatile endogenous GH and IGF-1 release. FDA-approved (Egrifta) for the reduction of excess abdominal visceral fat in HIV-infected patients with lipodystrophy.
- Visceral adipose tissue reduction (approved)
- Cognitive function in older adults (research)
- NAFLD / hepatic fat (research)
- • FDA-approved only for HIV-associated lipodystrophy.
- • May affect glucose tolerance; monitor in at-risk patients.
- • Requires physician oversight.
