Description
Mazdutide
THIS IS NOT FOR HUMAN CONSUMPTION. SOLD FOR RESEARCH ONLY!
Mazdutide is a dual GLP-1/glucagon receptor agonist currently in clinical development, engineered — like retatrutide but with a different receptor-activity ratio — to combine GLP-1's established glycemic and appetite-suppressing effects with glucagon receptor agonism, which is studied for its contribution to increased energy expenditure and hepatic fat oxidation. Published Phase 2/3 clinical trial data (largely from research conducted in China, where mazdutide has advanced furthest in development) has reported body-weight and glycemic outcomes competitive with other next-generation incretin therapies, with particular research interest in its effect on liver-fat content, given glucagon receptor activity's established role in hepatic lipid metabolism. Mazdutide sits within the broader current wave of multi-receptor incretin research exploring whether combining GLP-1 with complementary metabolic-hormone pathways (glucagon or GIP) can improve on the efficacy ceiling observed with single-pathway GLP-1 therapies alone.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY

Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
