GHRP-6- Summary
- Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.
- GHRP-6 is the original synthetic GH-releasing peptide and a potent ghrelin receptor agonist. It produces strong GH pulses but is notorious for a significant hunger surge 30–45 minutes post-injection. This hunger side effect makes it less preferred than Ipamorelin or GHRP-2 for most protocols but can be useful in patients with appetite deficiency.
