Exenatide- Summary
- Ipamorelin is a selective GHRP (growth hormone releasing peptide) and one of the cleanest GH secretagogues available. It selectively stimulates GH release without significantly raising cortisol, prolactin, or appetite — making it ideal for long-term use and anti-aging protocols.
- Exenatide is a GLP-1 receptor agonist derived from the Gila monster lizard peptide exendin-4, with 53% homology to human GLP-1 and natural resistance to DPP-4 degradation. Available as twice-daily (Byetta) or once-weekly (Bydureon) formulation, it is also being studied for Parkinson's disease neuroprotection.
