HGH 191AA – Product Information

HGH 191AA refers to a form of synthetic growth hormone peptide (HGH) that is comprised of 191 amino acids. The “AA” in its name stands for amino acid, indicating the specific composition of the hormone.

What is HGH 191AA?

HGH 191AA (human growth hormone 191AA) is a peptide produced by the pituitary gland, an endocrine gland. It is used to activate the human growth hormone. This process stimulates somatostatin production, which is also known as GHIH (growth hormone-inhibiting hormone)

HGH 191AA is made up of 191 amino acids. Research has shown that HGH is essential for growth, cell regeneration, and reproduction. Aside from that, this hormone has anabolic effects on muscle and bone and catabolic effects on white adipose tissue. [R]

How does HGH 191AA Work?

HGH works by stimulating metabolic processes in cells to activate the metabolism. This peptide hormone stimulates the liver to make an insulin-like protein. The protein produces cartilage cells, which, in turn, stimulate muscle protein synthesis, as well as bone and organ growth. [R]

HGH also demonstrates the ability to induce adipose tissue lipolysis (fat breakdown). The ability of growth hormones to reduce fat volume and distribution is well accepted. In addition, GH has also proven to have an inhibiting effect on the action of insulin. [R]


Insulin-like growth factor 1 (IGF-1) is a hormone that manages the effects of growth hormone. Together, GH and IGF-1 promote the natural growth of tissues and bones. The metabolic effects of these two hormones, however, are different.

GH treatment leads to elevated glucose and insulin levels. It also causes impaired glucose tolerance and reduced insulin sensitivity. IGF-1 treatment, on the contrary, leads to enhanced insulin sensitivity, and reduced insulin and glucose levels. [R]

Yet another difference is the location where these hormones are produced in the body. While HGH is produced by the anterior pituitary gland located in the brain, circulating IGF-1 is generated by the liver. Its synthesis is regulated by the pituitary secretion of GH.

HGH GMP 98% vs. HGH 191AA

HGH GMP 98% and HGH 191AA are both forms of human growth hormone (HGH), but they refer to different aspects of the hormone. HGH 191AA refers to the specific sequence of 191 amino acids that make up the hormone. This is the natural form of HGH produced by the human body and is the most commonly used form of HGH in medical treatments.

HGH GMP 98% refers to the purity of the HGH. GMP stands for Good Manufacturing Practice, which is a set of guidelines for ensuring the quality and safety of pharmaceutical products. HGH GMP 98% means that the HGH has been manufactured according to these guidelines and is at least 98% pure. So while HGH 191AA refers to the specific amino acid sequence of the hormone, HGH GMP 98% refers to the quality and purity of the HGH product. It’s possible to have HGH that is both 191AA and GMP 98%, but they are not the same thing.

HGH Research

The effects of HGH have been explored in clinical, experimental, and animal studies. These have shown that growth hormone positively affects the cardiovascular system, improves insulin signaling, and improves sleep quality. Let’s take a detailed look at studies involving HGH.

HGH and Cardiovascular Health

An animal study suggests that treatment with GH results in increased ventricular contractility in rats with left ventricular dysfunction. These results indicate that GH treatment may improve cardiac function by both increased myocardial contractility and decreased vascular resistance in heart failure. [R]

In a clinical study, recombinant GH was administered to patients with idiopathic dilated cardiomyopathy. The treatment results in the improvement of hemodynamics, myocardial energy metabolism, and clinical status. These results open new perspectives on the use of GH in heart failure. [R]

All in all, enough evidence from growth hormone deficiency studies has been produced to suggest a physiological role for the GH/IGF-1 axis in the control and regular of several metabolic cardiovascular risk factors. [R]

HGH and Muscle Strength

A clinical study was conducted to assess the effect of GH therapy on muscle strength in healthy male subjects over 50 years old. After six months of treatment, increased muscle strength in the lower body part was observed in healthy men. [R]

Moreover, a review was conducted to examine the evidence that GH has metabolic effects in adult human beings. It concluded that GH does indeed have potentially powerful effects on fat and carbohydrate metabolism. In particular, GH promotes the metabolic use of adipose tissue triacylglycerol. [R]

HGH and Healing

A number of studies have shown that GH is a promising agent in the acceleration of wound healing. In addition to the stimulation of granulation tissue formation, GH may increase collagen deposition and facilitate epithelialization. [R]

Results from an animal study identify another function of growth hormone-releasing hormone in promoting skin tissue wound healing and repair. Findings from the study suggest that GHRH may have clinical utility for the augmented healing of skin wounds. [R]

HGH and Skin

A 2013 study set out to explore the effects of growth hormones on the skin. The study’s authors concluded that GH plays an important role in developing, maintaining, and repairing the skin. In fact, the dermal structures reflect the various changes in GH production occurring during life. [R]

However, both GH excess, as in the case of acromegaly in adults, and GH deficiency lead to skin manifestations. In the case of GH excess, skin thickening, puffy hands and feet, and oily skin are the main dermatological findings. GH deficiency, meanwhile, is characterized by thin, dry skin. [R]

HGH and Anxiety

Is growth hormone deficiency (GHD) associated with anxiety disorder? A study was conducted to investigate the relationship between GHD and anxiety disorders and depression in children and adolescents.

Results show that generalized anxiety disorder (GAD) and social anxiety disorder (SAD) were significantly more common in children with GHD compared to the control group. Receipt of GH treatment significantly reduced GAD and SAD rates in the GHD group. [R]

HGH and Appetite

Ghrelin is a recently discovered gastric peptide that increases appetite. A recent study set out to investigate the role of GH on circulating levels of ghrelin. It found that the GH/IGF-1 axis has a negative feedback on ghrelin secretion. [R]

Yet another study was conducted to investigate the effect of GH therapy on appetite-regulating hormones. Following 4 months of GH therapy, nine pre-pubertal children with idiopathic short stature experienced a reduction in ghrelin. This suggests a role for GH in appetite regulation. [R]

HGH and Height

Data indicate that GH therapy, on average, increases adult height by 4 to 6 cm for children with idiopathic short stature. The data is obtained from a study presented in part at the annual meeting of the Endocrine Society, San Diego, California, in June 1999. [R]

GH treatment was found to be safe. There were no significant adverse events.


What does HGH do to the body of research subjects?

HGH regulates many aspects of the metabolism. It regulates the fat, muscle, and tissue in bodies and other aspects such as blood sugar levels and insulin secretion. In addition, HGH stimulates growth, cell reproduction, and cell regeneration.

What is growth hormone deficiency?

Growth hormone deficiency (GHD) is caused by insufficient amounts of GH in the body. GHD can be congenital (present at birth) or acquired (develop later). In adults, GHD can lead to poor bone density and reduced muscle mass. HGH injections are the most common treatment for this condition. Purerawz sells HGH for research purposes only.

Is HGH 191AA legal?

HGH 191 AA is legal to buy and sell as a research chemical. Purerawz sells HGH 191AA for research purposes and not for veterinary or human consumption.
