What is ATX-304 Capsule?
ATX-304 (also called O-304, CAS#1261289-04-6) is a synthetic small-molecule pan-AMPK activator.
AMPK is the body's "metabolic master switch." It controls energy balance, blood sugar, and fat metabolism.
ATX-304 directly activates AMPK. Unlike metformin (which works indirectly), ATX-304 stabilizes AMPK in its active form.
ATX-304 is currently in clinical development. Cambrian Bio is leading Phase 1b/Phase 2 trials for obesity and cardiometabolic diseases

FAQ
Q: Did we support OEM?
A: Yes,capsule, label ,package, we support all OEM .
Q: How long does it take to ship?
A: Standard capsules: Ships within 1-3 days. Customized specifications: Ships within 2-5 days.
Q: How does ATX-304 work?
A: It directly activates AMPK – the body's energy sensor. This boosts fat burning, glucose uptake, and mitochondrial function. It mimics the metabolic effects of exercise.
Q: Can ATX-304 be combined with GLP-1 therapy?
A: Researchers are evaluating this possibility. Early preclinical work suggests combination therapy may have potential, but more studies are required.
