Jacked Factory NITROSURGE Shred Pre Workout Supplement - Energy Booster, Instant Strength Gains, Sharp Focus, Powerful Pumps - Nitric Oxide Booster & PreWorkout Powder - 30Sv, Watermelon

This does give me great energy, but the itchy feeling which their website states is normal makes me uneasy. I have not had that occur with other pre-energy workout powders. For that reason, I don’t think it’s worth it. Flavor is good but a little too sweet for my taste.

Seems to work ok, it is a fair price

I wanted to try a pre-work out to help get me started on workouts when I'm exhausted at the end of the day and not feeling it. This is the first one I've tried and I'm not sure it's for me. I didn't have any clumps in my container like some other reviewers mentioned. The flavour was intense, almost like fluoride and aspartame. Kind of hard to get down. Within 15-20 minutes I was jittery with tingly pins and needles all over my body. I did feel very energized and focused for most of my workout but I crashed hard after about an hour and 15 minutes... Before I had finished my workout. I didn't have any adverse digestive symptoms that I've heard some people struggle with when taking pre-work out. I think next time I might try just half a scoop so I don't get so jittery and tingly and hopefully prevent the intense crash that I experienced. I don't think it's a bad product, but maybe too intense for my body.

My partner liked this pre-workout at first but got sick of the taste after about a month—it has a very strong flavor. That said, it definitely gets the job done and works as intended. If you don’t mind intense flavors, it’s a solid choice.

Overall, I felt the pre didn't meet my expectations because when comparing it to other pre-workouts that I have taken I really didn't feel the pump and strength like I thought I would. I didn't feel any tingling or niacin - but, I like that tingling sensation so - to me - that was a bummer. The 'umph' factor just wasn't there for me when taking this product, but it could be because I am used to taking other pre-workouts that are stronger or have more of other ingredients than in this one. I usually drink my pres during my actual workout to try to train as long as I possibly can or until I hit 1.5 to 2 hours (which ever comes first). However, when doing my usual routine with this pre, I felt a little bit of kick after I had finished my workout. I did find that this pre really does work better when you start drinking it 30 minutes before you work out and if you take the recommended two scoops like it says on the label. Really, if you follow the instructions on the label it works - I would say - comparable to other pre-workouts. However, on the downside this really doesn't leave any room to adjust it to your routine (at least in my case). I will say though, the flavor factor was definitely there. I don't think I have ever had a watermelon flavor that tasted as close to watermelon as this one does. It's sweet and enjoyable to drink rather than other pres that have a bitter aftertaste or just sour overall. The flavor really was the winning factor for me on this pre-workout, but the effect I wanted to get as far as strength and pump - I didn't see or feel at all.
