I use Jack3d. Only two scoops, and only on the days I lift. I don't use any other stimulants though throughout the day. No coffee, thermogenics, green tea, etc. I tried NoXplode too, and swore off all BSN products shortly afterwards.
Lots of people are weary of the Dimethy 1,3 in there, but everyone that has complained seems to overstack their stimulants. I've had no bad effects from it, and it also supplies the small amount of creatine monohydrate to make up for my lack of red meats. The only thing that it really isn't, which NoXplode was is NO2. But I don't really miss that at all to be honest. I was actually going to try Yok3d, but the timing to take it is really odd. 2 hours preworkout with a meal, or 90 minutes prior on an empty stomach. Really hard to plan if your schedule isn't allowing
I would run to GNC (I know, but hear me out) and pick up some. The reason I say GNC, is because I know that if you try it, and don't like it, they let you return the open container and get a full refund of your money
