HGH Fragment 176–191

HGH Fragment 176–191 is a synthetic peptide corresponding to amino acids 176–191 of human growth hormone. It selectively activates beta-3 adrenergic receptors in adipose tissue, stimulating lipolysis without the hyperglycemic or mitogenic effects of full-length GH. Supplied as ≥99% pure lyophilized powder for in vitro and preclinical research.

Research Overview

• Selective beta-3 AR-mediated lipolysis in adipose tissue without altering blood glucose (Heffernan et al., 2001)
• Inhibition of lipogenesis from dietary carbohydrates and fat in animal models (Ng & Waters, 2004)
• Equivalent lipolytic activity to full-length GH at significantly lower doses in preclinical studies
• No observed impact on IGF-1 levels, insulin sensitivity, or cartilage growth in research models
• Favorable safety profile in Phase I/II human trials conducted by Metabolic Pharmaceuticals (Australia)

Biochemical Properties

• Sequence: Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe
• Molecular Weight: ~1,815 Da
• Half-Life: Minutes (plasma); subcutaneous administration extends bioavailability
• Form: Lyophilized powder, ≥99% purity (HPLC-verified)
• CAS Number: 221231-10-3
