TF?Frag, also known as HGH Fragment 176?191, is a synthetic peptide derived from the C?terminal fragment of human growth hormone, covering amino acid residues 176?191 of hGH sequence. It retains the lipolytic?related biological activity of native human growth hormone, while showing minimal impact on growth?promoting pathways and IGF?1 secretion compared with full?length HGH.

This peptide is widely adopted in pre?clinical research for lipid metabolism, lipolysis mechanism, adipocyte function, obesity model and energy expenditure studies. It can be applied for in?vitro cell assays and in?vivo animal metabolic experiments to explore fat mobilization and lipid?regulating signaling pathways.

Our TF?Frag peptide is produced via solid?phase peptide synthesis process. Each batch is strictly verified by HPLC and mass spectrometry to guarantee high purity and accurate molecular sequence. COA document is available upon customer request. Lyophilized powder form ensures stable performance during transportation and long?term preservation. Multiple packaging specifications are supported, ranging from small laboratory sample vials to bulk kilogram?level orders.
