HGH Fragment 176-191 Pen

1000.00 AED — In stock

HGH Fragment 176-191 is a stabilised analogue of amino acids 176 through 191 of the human growth hormone (hGH) polypeptide. It is specifically studied for its influence on fat metabolism - retaining the lipolytic (fat-burning) properties of full growth hormone while operating through a more targeted mechanism. What HGH Fragment 176-191 is studied for: Fat metabolism and lipolysis - Studied extensively for its ability to stimulate the breakdown of stored fat (lipolysis) and inhibit the formation of new fat cells (lipogenesis), particularly in areas of stubborn adipose tissue Body composition support - Research highlights its role in supporting lean body composition without the growth-promoting or insulin-affecting properties associated with full hGH Metabolic regulation - Studied for its influence on metabolic rate and energy utilisation, with particular interest in visceral fat reduction Weight management research - One of the most studied peptides in the context of metabolic health and body composition optimisation HGH Fragment 176-191 is widely researched as a precision tool for those studying fat metabolism independently of broader growth hormone pathways.

What is HGH Fragment 176-191 Pen?

HGH Fragment 176-191 is a short synthetic peptide matching the final section of human growth hormone, amino acids 176 to 191. Researchers identified this region as the part of the hormone most linked to its effects on fat metabolism.

The fragment does not appear to act on the main growth hormone receptor in the way the full hormone does. It is closely related to AOD-9604, a modified version of the same region that was developed for formal study. It is thought to influence fat breakdown in fat cells.

Also known as: hGH 176-191, Frag 176-191, GH fragment 176-191, Growth hormone fragment

What are peptides?

What the research covers

Research on growth hormone fragments comes mostly from animal studies in the 1990s and early 2000s. In obese mice and rats, C-terminal growth hormone fragments have been studied for effects on fat breakdown and fat oxidation, without the effects on growth or blood sugar seen with full growth hormone. Most later human data relate to the modified form, AOD-9604, rather than the unmodified fragment. Early research suggests a possible role in fat metabolism, but human evidence is limited. HGH Fragment 176-191 is not approved as a medicine by the US FDA.

Frequently asked questions

Is it the same as growth hormone?

No. It is a small piece of the growth hormone molecule. It does not appear to have the growth-related effects of the full hormone.

How does it compare with AOD-9604?

AOD-9604 is a modified version of the same region with an added tyrosine. Most formal animal and human research was carried out on AOD-9604.

What formats are available and how are they stored?

It is available as a pen or a vial. Keep pens in the fridge, and refrigerate vials after reconstitution, away from light. Follow the storage instructions on your pharmacy label.

Are there side effects?

Side effects can occur. Your GP will review your health, medication and, where relevant, blood results before prescribing, and you should report anything unexpected.

How much should I take?

Your dose is set by our licensed GP following a consultation, and printed on your pharmacy label.
