How is tesamorelin different from sermorelin or CJC-1295?

All three are GHRH analogs, but tesamorelin is a full 44-amino-acid version with an N-terminal hexenoic acid for DPP-IV resistance. Sermorelin is the shorter 29-residue truncation with a shorter half-life, and CJC-1295 uses either tetrasubstitution (no-DAC) or covalent albumin binding (DAC) for different duration profiles. Tesamorelin has the strongest clinical dataset.

Why does tesamorelin reduce visceral fat specifically?

GH itself preferentially mobilises visceral adipose tissue because visceral fat is more sensitive to catecholamine and GH-driven lipolysis than subcutaneous fat. Tesamorelin generates a physiologic GH pulse that targets exactly this compartment, which is why VAT drops while SAT is largely preserved.

Does tesamorelin raise blood sugar?

Like any GH-driven protocol, tesamorelin can transiently raise fasting glucose and worsen insulin sensitivity because GH opposes insulin action. Clinical trials reported modest glycemic changes that are typically manageable but warrant monitoring in research protocols.

How should tesamorelin be stored?

Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C, protect from light, and use within the peptide's typical stability window. Avoid shaking, which can denature the peptide.

Stabilised GHRH 1-44 Analog - Visceral Fat Reduction

Tesamorelin is a synthetic version of your body's growth hormone–releasing hormone (GHRH), containing the full 44 amino acid sequence with a small chemical cap added for stability. It is the only GHRH-type peptide to have received FDA approval (sold as Egrifta) for reducing excess belly fat in HIV-related fat redistribution - giving it more clinical data than almost any other peptide in this class.
