Description
hGH Fragment 176–191 is a synthetic research peptide corresponding to a specific C-terminal region of the human growth hormone (hGH) sequence, comprising amino acids 177–191. In laboratory research settings, this peptide fragment is studied for its role in metabolic signaling pathways that are distinct from classical growth hormone receptor and IGF-1 receptor activation.
Experimental studies indicate that hGH Fragment 176–191 modulates lipid and glucose metabolism through β-adrenergic–associated signaling and AMP-activated protein kinase (AMPK)–mediated pathways in controlled in vitro and preclinical models. Due to its receptor-independent signaling profile, this fragment serves as a useful molecular tool for examining energy regulation and metabolic peptide function without engaging canonical somatotropic growth pathways.
hGH Fragment 176–191 is supplied exclusively for scientific and laboratory research use. It is not intended for human or veterinary consumption, clinical investigation, diagnostic use, or therapeutic application.

IGF-1 LR3
IGF-1 LR3 1mg – Research Peptide
For Research Use Only – Not for Human Consumption IGF-1 LR3 (Long Arg3 Insulin-Like Growth Factor-1) is a synthetic peptide analog of human IGF-1. It has been modified to extend its half-life in vitro, allowing for enhanced stability and prolonged activity during laboratory testing. The substitution of arginine at position 3 and removal of the first three amino acids in the native IGF-1 sequence make LR3 more resistant to binding proteins, thereby increasing its bioavailability in research environments. Researchers value IGF-1 LR3 for its role in studying cellular growth, differentiation, survival pathways, and metabolic functions. It has been widely used in experimental models to explore muscle cell proliferation, neuroprotection, and regenerative mechanisms.
