The combination of Retatrutide and Tirzepatide in a single formulation supports research protocols examining multi-receptor incretin pathway interactions or comparative receptor agonism studies. Tirzepatide acts on GIP and GLP-1 receptors, while Retatrutide adds glucagon receptor co-agonism. This blend is relevant for advanced metabolic research programs investigating the overlapping and additive pharmacology of incretin-class compounds across receptor systems.

- Short-term (reconstituted): Store at 4°C; use within 28 days
- Keep in original sealed vial until point of use
How should I store this peptide?+
Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.
What should I reconstitute it with?+
Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.
How quickly do orders ship?+
Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.
Is the COA verified independently?+
Yes. Every product is tested by HPLC for purity (target COA-verified purity) and mass spectrometry for molecular identity before release. The COA is generated from the actual test data, not a generic template.
Can I get bulk or institutional pricing?+
Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
