What is PYY(3-36)?
PYY(3-36) is an endogenous peptide fragment that promotes satiety through Y2 receptor signaling in the hypothalamus. It is widely used in human studies of appetite suppression and meal-size reduction.
Key Benefits & Mechanisms
satiety
reduced food intake
smaller meal size
appetite suppression
Research Summary
PYY(3-36) has repeatedly shown acute reductions in appetite and energy intake in experimental studies. Its main limitation is a short duration of action and variable tolerability, so it remains primarily a research peptide.
Related Peptides
Oxyntomodulin
Endogenous glucagon-like peptide 1 and glucagon co-agonist peptide
Oxyntomodulin is a naturally occurring proglucagon-derived peptide that activates GLP-1 and glucagon pathways. It is a key research tool for appetite suppression and energy balance studies in obesity.
Weight ManagementCotadutide
MEDI0382, long-acting GLP-1 and glucagon receptor dual agonist
Cotadutide is a synthetic oxyntomodulin analogue designed to engage both GLP-1 and glucagon receptors. It was developed to improve weight loss and metabolic markers in obesity and type 2 diabetes research.
Weight ManagementMazdutide
IBI362, long-acting GLP-1 receptor and glucagon receptor dual agonist
Mazdutide is a long-acting oxyntomodulin-inspired dual agonist being developed for obesity and metabolic disease. It is designed to drive clinically meaningful weight loss while improving glucose and lipid parameters.
Weight ManagementDulaglutide
Recombinant GLP-1 receptor agonist Fc fusion protein
Dulaglutide is a long-acting GLP-1 receptor agonist used primarily in type 2 diabetes. It consistently produces modest weight loss and is widely studied as a benchmark incretin mimetic.
