Precision Standards for Peptide Research

AOD-9604 (Advanced Obesity Drug 9604) is a modified synthetic 16-amino acid peptide fragment derived from the C-terminus of human growth hormone (hGH 177-191) with an added tyrosine residue at the N-terminus. It preserves the potent lipolytic and anti-lipogenic properties of full-length hGH while completely eliminating the somatogenic, IGF-1 stimulating, and diabetogenic/hyperglycemic actions of the intact hormone. AOD-9604 upregulates beta-3 adrenergic receptors (β3-AR) and stimulates adipose tissue lipolysis via hormone-sensitive lipase (HSL) activation.

L-Carnitine (L-3-hydroxy-4-N,N,N-trimethylaminobutyrate) and its acetylated derivative Acetyl-L-Carnitine (ALCAR) are quaternary ammonium amino acid derivatives essential for mitochondrial fatty acid oxidation. They serve as the critical rate-limiting cofactor for Carnitine Palmitoyltransferase 1 (CPT-1), facilitating the translocation of long-chain fatty acids across the impermeable inner mitochondrial membrane into the mitochondrial matrix for subsequent β-oxidation and ATP generation. In addition, ALCAR donates acetyl groups for the synthesis of acetylcholine and contributes to cellular antioxidant defense.

Retatrutide operates as an engineered tri-agonist peptide activating three distinct metabolic receptors: Glucose-Dependent Insulinotropic Polypeptide (GIP), Glucagon-Like Peptide-1 (GLP-1), and the Glucagon Receptor (GCGR). This triple synergy elevates hepatic mitochondrial oxidation while suppressing signaling for excessive nutrient intake.

Tirzepatide is a synthetic dual incretin mimetic peptide that targets both GIP and GLP-1 receptors. Its molecular conformation enhances glucose-dependent insulin secretion, slows gastric fluid transit time, and acts on hypothalamic satiety centers.

A GLP-1 analog engineered with an amino acid substitution at position 8 and a C-18 fatty diacid chain attached via a hydrophilic spacer. This modifications creates strong albumin binding, extending biological activity significantly.

A stable 15-amino acid sequence derived from human gastric juice protein. In vitro research illustrates its capacity to upregulate VEGFR2 (Vascular Endothelial Growth Factor Receptor 2) and activate the FAK-paxillin focal adhesion pathway.
