Semaglutide + Tesamorelin: Targeted Fat Loss
A dual-mechanism fat loss stack combining semaglutide's appetite suppression and GLP-1-mediated metabolic benefits with tesamorelin's targeted visceral fat reduction through GHRH agonism. Semaglutide promotes a sustained caloric deficit and improves insulin sensitivity, while tesamorelin specifically mobilises deep abdominal visceral adipose tissue by stimulating pulsatile GH release. The two agents operate through entirely non-overlapping pathways and address different fat compartments.
Safety Notes
Semaglutide is an FDA-approved prescription GLP-1 agonist carrying a boxed warning for thyroid C-cell tumour risk (observed in rodents; human risk not established). It requires a licensed prescriber and is contraindicated in personal or family history of medullary thyroid carcinoma or MEN2. Tesamorelin (Egrifta) is FDA-approved only for HIV-associated lipodystrophy; its use for general fat loss is off-label and outside its approved indication. This is a prescription-only combination not appropriate for unsupervised use.
Peptides in This Stack
- 1SemaglutideFat Loss
Reduces appetite and caloric intake via GLP-1 receptor agonism, improves insulin sensitivity, and drives broad body composition improvements — serving as the primary overall fat loss driver of the stack.
- 2TesamorelinFat Loss
Specifically targets visceral adipose tissue via GHRH-stimulated GH pulses that preferentially mobilise deep abdominal fat, addressing a metabolically harmful fat depot that GLP-1 agonism alone may not fully resolve.
