Ok- I already like and enjoy c4 and am looking for a good pre workout to cycle onto. My last cycle was no-eplode 2.0, but I didn't like it very much. Always gave me stomach issues. Is the Jack3d any good? Others? Looking for one that tastes good and gives me the push for my lifting and cross fit. Any known issues with taking these?

Jack3d is crazy. I like NO Xplod myself and Black Powder. Jack3d was either nerve racking or had no effect at all. Even after stirring and shacking the container. Not sure I would bother with it on top of it tastes terrible.

Thanks for the suggestion. I have read many reviews on Amazon that Jack3d did not have any effect. I'll check out Black Powder.

jack3d changed their formula... not sure how long ago. That could be the reason for the mix reviews. I read that original recipe was pretty crazy.

Maybe mdaa will make a come back.

I'm not currently taking any pre-workout, but I did back in late summer/early fall and took DS Craze. If you're into "pumps", it will not help a lot with that. Of course if you lift intensely enough and with volume, you'll get that good natural pump. But Craze really helps you focus.....a lot. Side affect alert.......... I had some weird dreams at night while taking it, so I stopped using it. My sleep is more important to me than some additional focus during my workouts. However, if I try a pre-workout again, I'll give Craze another try and maybe just workout earlier in the day or in the mornings and hopefully it will not mess with my sleep.
