Slim Xtreme stacked with Jack3d?

[Rockstar2004]

Current Stack : Animal Pak, ONS Whey Protein, SX, (new supp Jack3d)



I got my new tub of Jack3d Pre-workout. (Lots of hype, I?ll post my review later.)

In your opinion, is it wise to stack SX and Jack3d? I take 1 pill/day.

I've build a strong tolerance with stims/ caffeine.

I work out around 7pm 4-5 nights a week. Go to bed around 12pm everyday.

Wanted to find out if anyone has stacked any pre-workouts drinks with SX or jack3d specifically?

any serious side effects?

Thanks
