What is Retatrutide 40mg?
Retatrutide is the most potent weight-reduction compound currently in clinical development — a triple GLP-1R/GIPR/GCGR agonist producing 24.2% mean body weight reduction at 48 weeks in Phase 2 trials (the highest of any pharmacological compound in human clinical research). The 40mg/vial format provides a high-dose configuration suited for intensive research protocols. GLP-1R provides appetite suppression; GIPR enhances insulin secretion and adipocyte effects; GCGR adds direct hepatic fat mobilisation, brown adipose thermogenesis, and energy expenditure independently of food intake.
Research Applications
High-Dose Triple Agonist Research
40mg/vial provides a concentrated format for research requiring sustained high-dose retatrutide exposure — extended protocols, dose-response ceiling studies.
Triple Agonist Mechanism Research
GLP-1R + GIPR + GCGR simultaneous activation — research into which receptor combination drives superior outcomes vs dual or single agonist comparators.
Obesity Pharmacology — Phase 3 Range
40mg format aligns with upper Phase 2 dosing ranges — enables translational research at clinically relevant concentrations.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL of bacteriostatic water slowly down the side of the vial. Do not shake — gently swirl until the lyophilized powder fully dissolves. The resulting solution should be clear and colourless. Use a 1mL insulin syringe for accurate sub-milligram dosing.
How should this peptide be stored?
Store lyophilized vials at −20°C (freezer). Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Keep away from light and repeated freeze-thaw cycles. Do not use if the solution is cloudy or contains visible particles.
What purity is this QSC compound and how is it verified?
QSC Retatrutide is tested to ≥99% purity by analytical HPLC on every batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
