Customer Validation
By using stable isotope-labeled creatine and glycine (such as Creatine-d3 (HY-W010388S1) and 13C2-glycine), the mechanism of action of creatine in the aging process was deeply analyzed, providing a scientific basis for the development of new anti-aging strategies.

A) Metabolic flux analysis of 13C2-Glycine injected in iWAT and detection of labeled creatine in WAT.
B) Metabolic flux analysis of D3-Creatine injected in iWAT and detection of labeled creatine in QU muscle.
