Somatropin (HGH)- Summary
- Eloralintide is a long-acting amylin analog under development by OPKO Health. Amylin is co-secreted with insulin and regulates post-meal glucose by slowing gastric emptying, suppressing glucagon, and promoting satiety. Eloralintide is designed for once-weekly dosing, differentiating it from the short-acting pramlintide (Symlin). It is being studied for obesity and type 2 diabetes as a complement to GLP-1 based therapies.
- Somatropin is recombinant human growth hormone (rhGH), identical in structure to the 191-amino acid pituitary-derived growth hormone. It is FDA-approved for growth hormone deficiency, short stature, and wasting conditions. Off-label, it is widely explored for body composition, anti-aging, and performance enhancement, though significant risks accompany unsupervised use.
