HGH Fragment 176-191 5 mg

HGH Fragment 176-191 5 mg is Hilma Biocare's lipolytic peptide, supplied as a single lyophilised vial. It isolates the fat-mobilising region of growth hormone while avoiding the IGF-1 elevation associated with full somatropin.

What HGH Fragment 176-191 Is

HGH Fragment 176-191 is the C-terminal sixteen-amino-acid portion of human growth hormone. Researchers identified this region as the part of the hormone responsible for stimulating lipolysis and fat oxidation. Because the fragment lacks the rest of the growth-hormone sequence, it is studied for fat loss without the growth-promoting and IGF-1-raising effects of the full molecule. The 5 mg vial is the standard presentation.

The History of HGH Fragment Research

The fragment emerged from structure-activity studies of growth hormone in the late 1980s and 1990s, when researchers mapped which regions of the hormone drove which effects. The 176-191 sequence was found to reproduce the lipolytic action of growth hormone in animal models without affecting growth. It became a reference compound in obesity and metabolism research and later a popular peptide in fat-loss circles.

How It Works

The fragment binds to the growth-hormone receptor region involved in lipolysis and stimulates the breakdown of triglycerides in adipose tissue. It does not activate the pathways that produce IGF-1 or promote linear growth, which is the key pharmacological difference from somatropin. The peptide is short-lived and is typically studied with frequent administration. Its effects on fat oxidation have been demonstrated in animal models.

What the Research Shows

• Animal studies show increased lipolysis and reduced fat mass.
• Research indicates the fragment does not raise IGF-1 like full growth hormone.
• Structure-activity work mapped the lipolytic region of the hormone.
• Human data is limited compared with somatropin research.

Research Context

The appeal of HGH Fragment 176-191 lies in what it leaves out. Full growth hormone raises IGF-1, which can promote growth and affect glucose metabolism; the fragment is studied for lipolysis without those effects. Animal work shows increased fat oxidation and reduced fat mass, and the fragment does not appear to stimulate IGF-1 production in the same way. That selectivity is why it is often compared with somatropin in metabolic research. Human data is limited, and the fragment's short half-life means frequent administration in most study designs.

Strength, Pack and Authentication

Each vial contains 5 mg of lyophilised HGH Fragment 176-191, sealed and packed in a printed carton stating the compound, strength and vial count. A scratch-off security code inside the box links the pack to Hilma Biocare's records. The powder is stable before reconstitution and intended for research use only.
