Tesamorelin

Description

Firm Foundation Peptides’ Tesamorelin peptide is available in either 10mg and 20mg vials.

Tesamorelin is a synthetic peptide analogue of human growth hormone–releasing hormone (GHRH) engineered to preserve full GHRH activity while improving stability for research use. It contains the complete 44–amino acid sequence of native GHRH, along with a specialized N-terminal modification designed to enhance resistance to degradation.

A defining structural feature of Tesamorelin is the attachment of a trans-3-hexenoic acid group at the N-terminus. This modification helps protect the peptide from enzymatic breakdown and is associated with a longer functional duration compared to unmodified GHRH in laboratory models.

Tesamorelin is studied for its ability to bind GHRH receptors located in the anterior pituitary, supporting investigations into growth hormone release mechanisms and endocrine signaling. Due to its enhanced stability profile, it is frequently used in research related to pituitary function, growth hormone physiology, GHRH receptor pharmacology, and broader metabolic signaling influenced by growth hormone pathways.

For research use only.
