GHRP-6 vs Survodutide
Side-by-side comparison of key properties, dosing, and research.
Growth Hormone Peptides
GHRP-6GLP-1 / Weight Loss Agonists
Survodutide- Summary
- 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.
- Survodutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Boehringer Ingelheim and Zealand Pharma. Phase 2 trials demonstrated up to 18.7% body weight reduction at 46 weeks, among the highest reported for a dual agonist. It is being studied for obesity and MASH (metabolic dysfunction-associated steatohepatitis), where the glucagon component drives hepatic fat clearance.
