Tesamorelin

Tesamorelin is a stabilized synthetic analogue of growth hormone-releasing hormone engineered to extend peptide stability and receptor activity relative to endogenous GHRH sequences. It has been studied extensively in growth-axis research for its relationship to pulsatile growth hormone signaling, adipose distribution, and IGF-1 pathway activity across controlled clinical settings.

Growth · 10mg, 20mg · 3mL

Tesamorelin is a stabilized synthetic analogue of growth hormone-releasing hormone engineered to extend peptide stability and receptor activity relative to endogenous GHRH sequences. It has been studied extensively in growth-axis research for its relationship to pulsatile growth hormone signaling, adipose distribution, and IGF-1 pathway activity across controlled clinical settings. Its modified amino acid structure improves resistance to enzymatic degradation while preserving selective interaction with pituitary GHRH receptors. Lyophilized powder, 3mL vial. Sold at 10mg and 20mg per vial. For research use only.

44-aa GHRH analog. Peptide Sciences lists C223H370N72O69S / 5195.908 — possibly acetate salt form.
