Semaglutide (GLP-1 Analogue) 3mg
$110.00
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.
Description
GLP-1, short for glucagon-like peptide-1 is a short, naturally occurring peptide hormone just 30-31 amino acids in length. Its primary physiologic function is to lower blood sugar levels by naturally enhancing insulin secretion. It also plays roles in protection beta cell insulin stores by promoting insulin gene transcription and has been linked with neurotrophic effects in the brain and central nervous system. In the GI system, GLP-1 has been shown to significantly decrease appetite by delaying gastric emptying and reducing intestinal motility. Preliminary research has shown impacts of GLP-1 in the heart, fat, muscles, bones, liver, lungs, and kidneys as well.
The primary focus of GLP-1 research has been in the realm of diabetes treatment/prevention as well as appetite suppression. Secondary research focuses on the potential cardiovascular benefits of the peptide. More recent, and thus less robust, research focuses on the ability of GLP-1 to stave off neurodegenerative disease. Though this latter area of research is newest, it is also the fast-growing area of GLP-1 study now that the peptide has been revealed to slow or prevent the accumulation of amyloid beta plaques in the setting of Alzheimer’s disease.

The Incretin Effect of GLP-1
Perhaps the most important effect that GLP-1 has, according to Dr. Holst, is referred to as the “incretin effect.” Incretins are a group of metabolic hormones, released by the GI tract, that cause a decrease in blood glucose (sugar) levels. GLP-1 has been shown to be one of the two most important hormones (the other being GIP) to stimulate the incretin effect in rodent models. Though GIP circulates at levels roughly 10 times higher than that of GLP-1, there is evidence that GLP-1 is the more potent of the two molecules, particularly when levels of blood glucose are quite high.
A GLP-1 receptor has been identified on the surface of pancreatic beta cells, making it clear that GLP-1 directly stimulates the exocytosis of insulin from the pancreas. When combined with sulfonylurea drugs, GLP-1 has been shown to boost insulin secretion enough to cause mild hypoglycemia in up to 40% of subjects
The Incretin Effect of GLP-1
Research in animal models suggests that GLP-1 can stimulate the growth and proliferation of pancreatic beta cells and that it may stimulate the differentiation of new beta cells form progenitors in the pancreatic duct epithelium. Research has also shown that GLP-1 inhibits beta cell apoptosis. Taken in sum, these effects tip the usual balance of beta cell growth and death toward growth, suggesting that the peptide may be useful in treating diabetes and in protecting the pancreas against insult that harms beta cells.
In one particularly compelling trial, GLP-1 was shown to inhibit the death of beta cells caused by enhanced levels of inflammatory cytokines. In fact, mouse models of type 1 diabetes have revealed that GLP-1 protects islet cells from destruction and may, in fact, be a useful means of preventing onset of the type 1 diabetes
