Blackstone tonic is very good for fitness. Each capsule of RecompRX in Blackstone Laboratory contains ursolic acid, although ursolic acid has remarkable characteristics, including reducing estrogen level, increasing 1GF- 1 in blood stream, and resisting catabolism in vivo. However, the bioavailability of ursolic acid is low, which means that no matter how much ursolic acid you consume, your body can only use a very small amount of ursolic acid, which makes the overall effect worse. This is a difficult problem. Therefore, Blackstone Laboratory adopted the microemulsion drug delivery system SMEDSRXTM, which increased the bioavailability of ursolic acid, which means that your body will make full use of it as much as possible.
