O-304 (also designated ATX-304 and OS-01) is a first-in-class, orally bioavailable pan-AMPK activator — meaning it activates all 12 AMPK heterotrimer complexes, unlike earlier allosteric activators (e.g., A-769662) that show complex selectivity. Clinical Phase I/II data demonstrate improvements in insulin sensitivity, fatty acid oxidation, and glucose uptake without the risk of hypoglycaemia. These capsules (150mg per capsule, 30 capsules) are formulated for research protocols examining whole-body metabolic activation.
O-304 is studied in type 2 diabetes, AMPK biology, fatty liver disease, exercise physiology, and longevity research. Mechanistically distinct from and complementary to AICAR (indirect AMPK activation) and MOTS-c capsules (mitochondrial AMPK signaling).

Third-Party Verified
We don't just claim purity — we prove it. Every batch of O-304 Capsules (150mg) is independently tested by an accredited third-party laboratory before it reaches you. Your COA is linked to your specific lot number.

Third order now. Consistent batch-to-batch results matter enormously in long-term research. Certificate of Analysis is detailed with mass spec data. Would not switch sources.
Verified against our reference standards. Purity >98.2% by HPLC. Packaging was appropriate for temperature-sensitive peptides. Will re-order.
