Buy Fragment 176-191 Research Peptide

Isolation of a 16-amino acid C-terminal region from the full-length growth hormone sequence produced a peptide fragment with a distinct signalling profile. Fragment 176-191, also referred to as HGH Frag 176-191 (CAS 66004-57-7), carries the molecular formula C78H123N23O23S2 and a molecular weight of 1815.13 g/mol. Produced via solid-phase peptide synthesis.

In vitro studies using adipocyte cell models have investigated the compound's interaction with lipolytic signalling cascades, exploring whether HGH Frag 176-191 activates beta-adrenergic-adjacent pathways without engaging the JAK2/STAT5 axis. In vivo rodent models have examined the pharmacokinetic profile and tissue-specific distribution of the fragment relative to full-length recombinant growth hormone.
