Metabolic research peptides, shipped within Canada.
Incretin-class peptides are the most-studied molecules in metabolic research: appetite signalling, glucose handling and energy expenditure. We stock the triple agonist retatrutide, and the library covers tirzepatide and semaglutide for comparison so a study design can be read against the class, not just the vial.

Questions researchers ask
- What is the difference between retatrutide, tirzepatide and semaglutide?
- Receptor count. Semaglutide is a GLP-1 receptor agonist. Tirzepatide adds GIP. Retatrutide adds a glucagon-receptor arm on top of both, which is the design difference behind its reported effects on energy expenditure. All three carry a fatty-acid side chain for albumin binding and once-weekly kinetics.
- Which vial size should a lab order?
- Retatrutide ships in 10 mg and 20 mg vials. The protocol page shows the reconstitution concentration for each size separately, because the same solvent volume gives a different stock concentration in each.
- Is tirzepatide in stock?
- Tirzepatide is listed and periodically out of stock. The product page takes an email and notifies you the day a lot lands.
