it's a waste of money. Two of my good mates tried it and said exactly that.
Beware. USP Labs is one company known to blow their products out of proportion with their shady marketing. And amongst that, they have a history where their reps manipulate the product ratings through false accounts and info.
But to be fair, I must say I tried Jack3d and it was a good pre-WO supp.
The other two USP products i tried for when i was losing fat were Anabolic Pump and Powerfull. Anabolic Pump did nothing while Powerfull just made me sleep a bit deeper (just a bit). Nothing in terms of faster recovery
