Retatrutide

Retatrutide is a synthetic 39-amino acid triple agonist engaging the GIP, GLP-1, and glucagon receptors, developed on a GIP peptide backbone with a fatty-diacid modification. Supplied as a lyophilized powder for research applications.

Tirzepatide

Tirzepatide is a synthetic 39-amino acid dual GIP/GLP-1 receptor agonist based on the native GIP sequence with a conjugated fatty diacid chain. Supplied as a lyophilized powder for research and compounding applications.

Semaglutide

Semaglutide is a synthetic 31-amino acid GLP-1 receptor agonist featuring an Aib substitution for enzymatic resistance and a fatty diacid side chain for extended half-life. Supplied as a lyophilized powder for research and compounding applications.
