Retatrutide.
A triple agonist at GLP-1, GIP, and glucagon receptors — lyophilized for scientific research applications. Third-party tested to 99.4% purity.

What it is
Three receptors. One molecule.
Insulin secretion. Glucose homeostasis. Slowed gastric emptying. The most-studied agonist class in modern metabolic research.
Glucose-dependent insulinotropic polypeptide. Receptor activation that complements GLP-1 with distinct downstream effects on adipose tissue.
Activation of the glucagon receptor — distinct from the others — drives energy expenditure pathways in preclinical models.
Verification
What goes in. And why.
Every batch of retatrutide is verified by ISO-certified third-party laboratories. Identity confirmed by mass spectrometry. Purity assessed by HPLC. Endotoxin and sterility tested before release.
- Identity confirmed by mass spectrometry
- Purity assessed by reverse-phase HPLC
- Endotoxin tested to <0.05 EU/mg
- Sterility verified before release

Storage. Handling. Stability.
Storage
- Store lyophilized vials at −20°C, protected from light.
- Short-term storage at 2–8°C is acceptable prior to reconstitution.
- Avoid repeated temperature cycling of sealed vials.
Reconstitution
- Reconstitute with bacteriostatic water for research preparations.
- Introduce solvent along the vial wall; do not agitate vigorously.
- Allow the powder to dissolve fully before handling.
Stability
- Lyophilized form is stable for extended periods when stored correctly.
- Reconstituted solutions are stored refrigerated at 2–8°C.
- Lyophilization preserves peptide integrity during transit.
