Tesamorelin
SKU: TSM10
Tesamorelin is a 44-amino-acid stabilized analog of GHRH with a trans-3-hexenoic acid modification that resists DPP-IV degradation. It binds GHRH receptors on anterior pituitary somatotrophs, stimulating pulsatile GH release, which in turn elevates hepatic IGF-1. Clinical trials …

Mechanism of Action
Tesamorelin is a 44-amino-acid stabilized analog of GHRH with a trans-3-hexenoic acid modification that resists DPP-IV degradation. It binds GHRH receptors on anterior pituitary somatotrophs, stimulating pulsatile GH release, which in turn elevates hepatic IGF-1. Clinical trials demonstrated preferential reduction of visceral adipose tissue (approximately 15-20% VAT reduction over 26 weeks) with minimal effect on subcutaneous fat. FDA-approved for HIV-associated lipodystrophy.

Compared with CJC-1295 + Ipamorelin in GH-axis research (Tesamorelin targets VAT preferentially; CJC-1295/Ipamorelin broader GH pulsatility). Frequently paired with GLP2-TZ or GLP3-RT in body composition research. Complementary to IGF-1 LR3 for downstream growth factor studies.
