About this product
RETATRUTIDE Canada — Triple Receptor Agonist for Metabolic Research Buying retatrutide in Canada just got easier. Kirei Clinic stocks 10mg research-grade vials of the triple receptor agonist that's generating more scientific interest than any GLP-1 compound since semaglutide. What separates retatrutide from the rest of the category is the glucagon receptor component. Semaglutide hits GLP-1. Tirzepatide adds GIP. Retatrutide activates all three simultaneously — GLP-1, GIP, and glucagon. That third pathway drives hepatic fat oxidation and energy expenditure in ways the earlier compounds couldn't achieve. One molecule addressing metabolic regulation from three distinct angles at once. Phase 2 clinical data published in the New England Journal of Medicine reported mean body weight reductions of 17.5% at 24 weeks in the highest-dose cohort — significantly beyond what single or dual agonists achieve in comparable timeframes. Researchers are particularly interested in visceral adiposity, glucose homeostasis, and the interplay between GIP and glucagon signalling. Research applications include metabolic syndrome investigation, glucose homeostasis studies, appetite regulation research, a...

Customer reviews
Frequently asked
questions
What is RETATRUTIDE used for?
RETATRUTIDE is a triple receptor agonist studied for metabolic research. Activates GLP-1, GIP, and glucagon receptors simultaneously for comprehensive metabolic regulation. Published research has examined its role in fat loss, appetite suppression, glucose metabolism.
Can I buy RETATRUTIDE in Canada?
Yes. Kirei Clinic ships RETATRUTIDE to all Canadian provinces — Ontario, British Columbia, Alberta, Quebec, Manitoba, Saskatchewan, and all territories. It's available strictly for non-clinical laboratory research purposes.
What purity is Kirei Clinic's RETATRUTIDE?
Every batch is independently tested to 99%+ purity by third-party HPLC. Mass spectrometry confirms peptide identity. A Certificate of Analysis documenting purity, molecular weight, and batch data is included with every order.
How should I store RETATRUTIDE?
Store lyophilized RETATRUTIDE at -20°C in the original sealed vial. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 4 weeks. Avoid repeated freeze-thaw cycles — aliquot if multiple uses are planned.
How do I reconstitute RETATRUTIDE?
Draw bacteriostatic water into a syringe and inject slowly against the vial wall — not directly onto the powder. Swirl gently to dissolve; never shake. Common volumes are 1 mL, 2 mL, or 2.5 mL depending on the concentration needed. Let sit for a minute if not fully dissolved.
Is RETATRUTIDE legal in Canada?
RETATRUTIDE is legal to purchase in Canada for non-clinical laboratory research. It is not approved by Health Canada for therapeutic use and is not intended for human consumption. Kirei Clinic sells it strictly for research applications.
How does RETATRUTIDE differ from semaglutide?
Both RETATRUTIDE and semaglutide are used in metabolic research research but work through different mechanisms. RETATRUTIDE is a triple receptor agonist. Researchers often study them in parallel to compare mechanism-specific effects.
What documentation comes with RETATRUTIDE?
Every order includes a Certificate of Analysis (COA) with: HPLC purity results (99%+), mass spectrometry data, batch number, manufacturing date, and expiry date. This provides full traceability for research records.
