Glucagon receptor agonism is thought to increase energy expenditure and promote fat breakdown, though the precise clinical significance of each component in humans continues to be investigated in ongoing trials

Peptide Therapy What Are Peptides

Mechanism of Action Peptide Sciences Retatrutide Retatrutide binds and activates three key receptors involved in metabolic regulation: GIP Receptor Agonism: Enhances insulin secretion and promotes nutrient storage GLP-1 Receptor Agonism: Reduces appetite, delays gastric emptying, and supports glucose control Glucagon Receptor Agonism: Increases energy expenditure and fat oxidation This multi-target synergy mimics physiological hormone cascades, offering superior therapeutic potential compared to single-receptor agents

If you've had an Ozempic headache or a semaglutide headache, it likely wasn't a direct result of your medication, but a knock-on effect of hypoglycemia or dehydration, both of which are known possible side effects of semaglutide and other GLP-1s
