HGH Fragment 176-191

HGH Fragment 176-191

HGH Fragment 176-191 is the C-terminal region of human growth hormone (amino acids 176–191), engineered to replicate GH's fat-burning activity while completely eliminating its growth-promoting effects. It is one of the most targeted fat-loss peptides available — pure lipolytic action with no impact on GH receptors, IGF-1, or insulin sensitivity.

How It Works

HGH Fragment 176-191 interacts with beta-adrenergic receptors on fat cells, stimulating hormone-sensitive lipase (HSL) to break down stored triglycerides. It simultaneously inhibits lipoprotein lipase (LPL), reducing fat uptake into adipocytes. The result is a dual fat-burning effect: more fat released, less fat stored.

Key Benefits

• Pure Fat Burning:: Activates lipolysis without engaging GH receptors or stimulating IGF-1

• Lipogenesis Inhibition:: Reduces fat storage by suppressing LPL activity

• No Growth Effects:: Does not promote linear growth or cause insulin resistance

• Body Recomposition:: Ideal for targeting stubborn fat while preserving lean mass
