BUY URB-597 ONLINE
URB-597 (also known as KDS-4103) is a synthetic compound that acts as a fatty acid amide hydrolase (FAAH) inhibitor. FAAH is an enzyme in the brain and body that breaks down anandamide, a naturally occurring endocannabinoid (a chemical similar to THC, the active compound in cannabis).
How It Works
URB-597 blocks FAAH, which prevents the breakdown of anandamide.
As a result, anandamide levels increase in the brain and body — indirectly stimulating cannabinoid receptors (CB1 and CB2) and producing effects similar to mild cannabis activation, but without THC or direct receptor binding.

Active Content
- The active chemical in URB-597 is the FAAH-inhibiting compound itself (no mixtures or plant materials).
- It does not contain cannabinoids (like THC or CBD) — instead, it acts indirectly on the body’s endocannabinoid system by preserving anandamide.
- In research-grade material, purity typically ranges from ≥98 % to ensure consistent enzyme inhibition activity.
