Incretin, glucagon & amylin receptor signaling
Weight management peptides act on distinct but complementary receptor systems. GLP-1 receptor agonists such as semaglutide and liraglutide mimic incretin signaling, studied for glucose-dependent insulin secretion and appetite regulation.
Tirzepatide adds GIP receptor agonism to GLP-1 activity, while retatrutide extends this to a triple GIP, GLP-1 and glucagon receptor profile under investigation for energy expenditure and adiposity. Cagrlintide targets amylin and calcitonin receptors, studied for satiety signaling and gastric emptying.
Peptide Sciences supplies these reagents strictly for laboratory research. All molecular data is disclosed per product; unverified values are explicitly marked. Literature references are sourced from PubMed / NCBI.
Weight loss peptides — frequently asked
What are weight loss peptides used for in research?
Weight loss peptides such as semaglutide, tirzepatide, retatrutide, cagrlintide and liraglutide are investigated in preclinical and clinical research for effects on appetite regulation, energy balance, glucose-dependent insulin secretion and adiposity. They are supplied strictly for laboratory research use only.
Which weight loss peptides does Peptide Sciences offer?
The Peptide Sciences weight-management range includes Semaglutide (GLP-1 agonist), Tirzepatide (dual GIP/GLP-1 agonist), Retatrutide (triple GIP/GLP-1/glucagon agonist), Cagrlintide (amylin/calcitonin agonist) and Liraglutide (long-acting GLP-1 agonist) — all supplied at 99%+ purity with COA documentation.
Do you ship weight loss peptides to the USA, Canada, Europe, Australia and New Zealand?
Yes. Peptide Sciences ships research-grade weight loss peptides to research customers in the United States, Canada, across Europe, Australia, New Zealand and South American markets. There is no minimum order, and shipping is free on orders from €500 (converted to your local currency).
