Anone tried jack3d watermelon

I just bought some jac3d watermelon. Kind of a crazy rush at first. Anyone had any experience with this stuff? Is it ok to use. Is it going to run my heart rate too high during a cardiio workout? I only ask because of the jittery feeling at first use.

Jac3d is pretty good but it might make you jittery. It does have Creatine as well, which you may not want just for cardio. If you're only doing cardio I would recommend something like White Flood (Controlled Labs) because it's zero calorie and just more of a stimulant that doesn't overdue it. Jac3d is better if you're going to do some lifting too. There's no reason not to use it, but something like White Flood might be better and White Flood is far more cost effective for what you want.

jack3d and most Nitric oxide pre workout supps will give you that jittery feeling..they also may increase your heart rate due to the caffiene and dialation of your blood vessels. they also may give you a tingly feeling in your extremities caused by beta alanine.

i would not suggest doing cardio after taking this...its meant for pumps and muscle endurance..not cardio endurance.

i have taken jack3d, no xplode and regular creatine...

Jack3d has lots of Caffeine, beta-alanine and 1,3D in it. These ingredients will definitely give you a tingly, jittery feeling. The caffeine and 1,3D will give you the extreme energy rush and jitters, while the beta-alanine will give you the tingles. I've used it many times previously and know lots of people who use it. It should be fine as long as you don't take more than the recommended dose. Jack3d is a very concentrated formula, so it doesn't take but one scoop for most people.
