The hGH Fragment 176-191 is a stabilized analogue of the lipolytic factor of growth hormone. Scientific literature indicates that while the intact hGH molecule (191 amino acids) exerts a wide range of effects including cell proliferation and insulin signaling, the specific region spanning residues 176-191 is primarily responsible for the hormone’s fat-reducing properties.

Research studies have focused on this peptide’s ability to mimic the regulation of fat metabolism by interacting with beta-3 adrenergic receptors, thereby stimulating the breakdown of adipose tissue (lipolysis) and inhibiting the formation of fatty acids (lipogenesis). Unlike full-length hGH, Fragment 176-191 does not appear to compete for the hGH receptor involved in IGF-1 secretion, making it a critical tool for researchers aiming to isolate metabolic effects from anabolic growth functions.

FAQ

What is the difference between hGH Fragment 176-191 and AOD9604?
Both peptides are derived from the same C-terminal region of hGH and share similar lipolytic properties in research. However, AOD9604 is a modified version of Fragment 176-191 (often with a tyrosine modification at the C-terminus) designed to have a longer half-life and greater stability in biological systems compared to the standard Fragment 176-191.

Does this peptide affect blood sugar levels like regular HGH?
Preclinical studies suggest that Fragment 176-191 does not negatively impact insulin sensitivity or blood glucose levels, unlike the full hGH molecule which can induce hyperglycemia. This makes it a distinct subject of study for metabolic regulation.

Is this product suitable for muscle growth research?
Fragment 176-191 is specifically isolated for its metabolic (fat-burning) properties. It lacks the domain of the hGH molecule responsible for binding to receptors that stimulate IGF-1 release and subsequent muscle hypertrophy (growth). Therefore, it is not typically used as a primary agent in muscle growth research models.

How is the peptide supplied?
It is supplied as a lyophilized (freeze-dried) powder in a sterile vial, requiring reconstitution with a suitable solvent (such as Bacteriostatic Water) before use in laboratory experiments.​

Ipamorelin 10mg
Ipamorelin 10mg $80.00

Ipamorelin is a pentapeptide and a synthetic ghrelin mimetic (acting as a ghrelin agonist) with high growth hormone (GH) releasing potency. Since it mimics ghrelin and binds to its receptors (GH secretagogues receptors) in the brain, it stimulates the release of GH in the pituitary gland; which leads to an increase in plasma GH levels, but also increased levels in GA tract, lungs, heart, liver, kidney and pancreas.

What differentiates Ipamorelin from other growth hormone releasing peptides is that it stimulates GH in a way that’s most similar to that of growth hormone-releasing hormone.

Cagrilintide is a long-acting amylin analogue, currently at the forefront of peptide research due to its rather interesting potential beneficial effect in individuals with diabetes. But what’s so special about amylin? Well, amylin is another peptide hormone, co-secreted with insulin, which inhibits food intake, delays gastric emptying, and, most importantly, reduces blood glucose levels.

 

Back to cagrilintide… it was originally developed to improve on the initial amylin analogue called pramlintide. The problem with pramlintide is its short half-life and undesired side effects.

 

Cagrilintide was (and still is being) developed to alter the half-life, potency and stability of pramlintide, and other amylin analogues.Since, it’s still a relatively new peptide, it still needs to undergo further research so we can make sure its as effective and safe.

BBG70 GLOW – BPC -157 10mg + GHKCU 50mg + TB500 10mg $180.00

BPC-157 5mg, TB-500 (Thymosin Beta-4) 5 mg , GHK-Cu 20 mg
(Total Glow Blend)

The BPC-157, TB-500 (Thymosin Beta-4), and GHK-Cu mix is a mix of three different peptides, measured at 5 mg of BPC-157, 5 mg of TB-500, and 20 mg of GHK-Cu, for a total of 30 mg.

Researchers have been interested in BPC-157, a peptide initially isolated from gastric proteins, because of its ability to promote the growth of blood vessels and healing of injured tissue through a range of cellular mechanisms.

TB-500, a naturally occurring fragment of a larger protein, is typically studied for its ability to migrate cells into injured areas. It encourages the formation of new blood vessels, and reduces inflammation, especially in muscle and connective tissue.

The third ingredient, GHK-Cu, is a low molecular weight copper-binding peptide that has been linked in studies to wound healing, collagen synthesis, and even hair growth stimulation.

 

Together, these three compounds appear to have an effect on the same biological processes, but with a broader effect than any of them would have in isolation.

For example, TB-500 and BPC-157 both cause the growth of new vessels, while GHK-Cu adds another layer of support by activating the growth of the cells that line blood vessels.

On the structural repair side of tissues, TB-500 enables cell migration by promoting actin activity, while GHK-Cu and BPC-157 both influence fibroblasts and collagen to offer support for stronger connective tissue.

A second point of overlap is in reducing inflammation and oxidative stress, and it may be here that researchers are hopeful for these peptides in longer-term recovery studies.

As a result of these synergistic and shared activities, the blend is being investigated for use in everything ranging from musculoskeletal trauma to wound healing and post-surgical recovery.

BPC-157, TB-500 10mg
BPC-157, TB-500 10mg $100.00

Body protection compound 157, or BPC for short, is a 15 amino acid segment of a specific body protection compound fragment. 

 

Research showed that BPC-157 presents itself with potent cytoprotective properties, protecting cells from gastric mucosal damage. Though this exact mechanism is not yet fully known, researchers believe it has to do with the brain-gut axis which enables the communication between central nervous and endocrine systems.

 

TB-500 is a synthetic variation of the naturally occurring Thymosin-beta-4, and is built up of 43 amino acids. This peptide plays an important role in polymerization regulation, cell proliferation, migration and differentiation. 

 

Putting these two peptides in a blend together gives a powerful cell protection effect, as well as improved recovery and differentiation on a cellular level.

Semaglutide
Semaglutide Price range: $80.00 through $140.00

Semaglutide is a derivative of the naturally occurring GLP-1, a peptide that has been shown to lower blood sugar levels and enhance insulin secretion. Research shows that Semaglutide may also improve heart, liver, and lung function while helping to slow or prevent the effects of Alzheimer’s disease. Research with Semaglutide has shown it can significantly decrease appetite by delaying gastric emptying and reducing intestinal motility. Glucagon-Like Peptide-1 (GLP-1) Analogs have been shown to stimulate insulin and suppress glucagon secretion in a glucose-dependent manner.

*THESE STATEMENTS HAVE NOT BEEN EVALUATED BY THE FOOD AND DRUG ADMINISTRATION. THIS PRODUCT IS NOT INTENDED TO DIAGNOSE, TREAT, CURE OR PREVENT ANY DISEASE.

Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analog. It was based on the 44 amino acids sequence of GHRH and contains a trans-3 hexenoic group to protect it from enzymatic degradation. These modifications allow it to be more stable and have a longer half-life.

 

Just like Sermorelin, Ipamorelin or GHRP-2, Tesamorelin is considered a growth hormone secretagogue (GHS) which stimulates the secretion of GH and increases the level of insulin-like growth factor (IGF-1). The importance of IGF-1 is it tends to be lower in patients with obesity, diabetes and especially in those with lipodystrophy.

CJC-1295, Ipamorelin 10mg $85.00

CJC-1295 with DAC is a synthetic peptide, analog of the growth hormone-releasing hormone. Though CJC-1295 without DAC has the same effect and stimulates the production and secretion of growth hormone, the addition of Drug Affinity Complex (DAC) is what increases its half-life allowing it to act longer and more potently. 

Research in animals also suggests that CJC-1295 with DAC stimulates insulin-like growth factor 1 (IGF-1) and plays a part in a number of physiological processes.
