HGH Fragment 176-191 Peptide Vial

HGH Fragment 176-191 is a modified form of the tail end of the human growth hormone molecule, specifically designed to fight fat. Scientific research has found it works by mimicking the way natural growth hormone regulates fat metabolism but without the adverse effects on blood sugar or growth that is seen with unmodified growth hormone.

HGH Fragment 176-191 Peptide Vial

Fragment 176-191 (a modified version of AOD9604) is a lipolytic fragment of the 176th and 191th amino acids from the human growth hormone (hGH). Fragment 176-191 was given this name because it has been shown to increase fat burning in laboratory mice with large fat stores.

While fragment 176-191 retains hGH’s fat-burning effects, it does not increase insulin-like growth factor-1 (IGF-1), negatively impact carbohydrate metabolism, alter insulin sensitivity, or increase long bone growth. The specific effects of fragment 176 191 allow it to be used to study human fat metabolism and possibly develop anti-obesity drugs.


Molecular Formula: C78H125N23O23S2

Sequence: Tyr-Leu-Arg-IIe-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe

Molecular Weight: 1817.12 g/mol

Physical Appearance: White Lyophilised Solid

Form: Sterile Filtered White Lyophilized

Solubility: Water Soluble

Storage: Peptides should be refrigerated at 4˚C or below for a period of up to 3 months. To prolong the life span of the peptides they may be placed in a freezer for up to 12 months. Once reconstituted peptides should be refrigerated/stored at 4˚C for up to 30 days.

Size: 2mg | 5mg | 10mg


Regulating Blood Sugar:

The c terminal end of hGH is responsible for its hypoglycemic (blood sugar lowering) actions in animals. For decreasing blood sugar, 176-191 is the most effective synthetic derivative. Secondary to an increase in plasma insulin levels[1].  HGH fragment 176- 191 may be used to treat prediabetes and type 2 diabetes.

Fat Loss And Fat Burning:

“Lipolytic fragment” peptide has been found to burn fat and reduce weight in mice. B3-AR (or ADRB3) production is thought to be involved as the agonist has been found to increase skeletal muscle thermogenesis and adipose tissue fat burning. Conversely, mice lacking ADRB3 do not benefit from hGH or fragment 176-191.

A three-week research study indicated higher fat burning related to fragment 176-191 correlates with increased energy expenditure and weight loss [2]. Even when exposed to frag 176 191 [3], only fat mice lost weight, while skinny mice did not. To study energy homeostasis, researchers can use secondary regulatory pathways for lipolysis instead of ADRB3.

Promotes Cartilage Renewal:
Though peptide 176-191 is primarily studied for its lipolytic properties, other potential benefits are being investigated.

For example, a Korean piece of scientific research found that fragment 176-191 could enhance the impacts of hyaluronic acid injections in boosting cartilage regeneration. Weekly injections of frag 176 191 increased laboratory measures of cartilage growth in rabbits, and co-administration of the peptide with hyaluronic acid (HA) increased effects even further.

Similarly, 176-191, alone or in conjunction with HA, reduces osteoarthritis disability. This may lead to advanced osteoarthritis therapies and even minimize the need for surgery in some cases [4].


HGH Fragment 176-191 is being studied extensively in the field of weight reduction and lipolysis to better understand energy homeostasis and fat metabolism. Connective tissue regeneration, in particular cartilage repair, is the most active secondary area of study.

176-191 HGH Fragment has been studied primarily on animals. While it retains the human growth hormone fat-burning properties, it does not increase IGF-1 levels, negatively impact carbohydrate metabolism, alter insulin sensitivity, or increase long bone development.

A 2013 Journal of Endocrinology and Metabolism study analyzed six trials of HGH Fragment 176-191 to assess the rate and magnitude of probable adverse effects. HGH Frag 176-191 did not affect glucose, glucose tolerance, insulin sensitivity, or IGF-1 levels compared to a placebo. This shows that HGH fragment 176-191 provides many of the benefits of hGH without the unfavourable side effects [5].
