I find with all the pre-workout products i use, they usually wear off after about a couple of weeks. what makes this any different?

Hi Justin

I dont see it being a problem. Just becareful of using too many stimulants pre workout. Can lead to lack of concentration and dehydration.

Id go fat burner in the AM and Jack3d before training.

Rob,
I was wondering what you thought of stacking Jack3d with Cytolean V2? I have taken Jack3d before (and loved it) – but am curious what your thoughts are about stacking it with the Cytolean V2. Currently, I have dropped my body fat to around 11%, and am looking to keep lowering that number, while maintaining my current strength. Thanks!

This is my second week using this product now and I have to say you were spot on when you said it was amazing. The focus and intensity of my workouts have gone through the roof. I have never pushed myself like this before at the gym. I have been working out o a regualar basis now for 2 years and I have tried a number of different products from creatine to no2 products and nothing compares to the quality and quanity of the workout I get with jack3d. It truly is an amazing product and I think anyone thts looking to get past the plateau when working out should deffinatly give this a try.

This stuff is great! Just comming off a really bad back injury and wanted something to get me back on top and I found it.Strength is going back up and I don’t get tired half way through my workout. If your looking for a great preworkout supplement this is the one.

I really liked Jack3d when i used it, I had great focus and energy. The only problem I experienced was about 30-45 minutes after my workout I usually felt like I needed a dirt nap and became very lethargic. Even with that though I’d still recommend it.

I bought Jack3d and loved it
It was one of the better Preworks I have tried
Only down side was that I had some trouble sleeping and found myslef wide awake at like 3 AM

I just recently bought a tub of Jack3d..and i took it bout 25 mins before i worked out ..it was by far the best preworkout supplement that i have tried…i had a crazy pump,was very focused while doing each rep,had a shitload of energy, It is overall a deadly product and i would recommend it to everyone
