The presence of small amounts of sugars (like sucrose) helps stabilize the peptide, as their hydrogen bonds mimic those of water and reduce moisture-related collapse
These medicines mimic the action of the naturally occurring hormone GLP-1, which is released by the intestine in response to food intake
Regardless of the benefits of these drugs, there have been studies that reported a link between GLP-1 receptor agonists and an increased risk of developing pancreatitis (inflammation of the pancreas), bowel obstruction, and gastroparesis (stomach paralysis)
GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is a naturally occurring tripeptide your body produces, but levels drop sharply with age, from roughly 200 ng/mL at age 20 to about 80 ng/mL by age 60
GHK-Cu, CJC-1295/Ipamorelin, Leuphasyl, and Argireline are all effective options for improving skin texture, reducing wrinkles, and improving overall skin health
