Concept X | Clinically Dosed Pre-Workout Powder | Contains Caffeine, L-Citrulline, Creatine, and Beta-Alanine | Gummy Worm | 20 Servings

I’ve been using this pre workout for about a year now and really like it! The taste is sour in my opinion and maybe a 4 out of 5 stars. It definitely gives me energy after a long day of work to get my workout done and out the way for the day! It’s a good size for your money. I do get tingly still after a year of using it but sometimes I don’t take it on days I don’t work or feel high energy. It lasts through my entire workout and I would say about an hour after but I do my best to get in and out the gym (I try to be in the gym about an hour and a half at max if I have to wait for machines).

I've been using PWO for 15+ years. Tried them all. This one is VERY intense. As others have mentioned, it is so intense that it may cause some nausea. I didn't experience that, but my brother in law did. The mixability is also very poor, but the manufacturer states that "settling may occur" and it sure does. That being said, there's an old saying around gyms that goes something like "You don't take PWO for the flavor". This product powers workouts like none other. Sustained energy/focus/pumps for 2+ hours. Check out the ingredient label. Massive amounts of staple ingredients. If you're into very strong PWO, give this ago. If intensity isn't your thing in this department, try something else.

This is the worst product I’ve purchased in the history of pre workout. Would not recommend. It came clumped together, not fully filled and tastes expired and like trash!!! The worst part is the product is illegible for a refund! So disappointed. Do NOT BUY IT

Very rare for me to go over 3 stars for anything. Especially if it tastes like this. Gummy Worm is not great, but was in stock. Now I know why. But otherwise it hits like spaz juice. Workout was better, and I felt like I was ready to go. Pricey. I think it works the best of what I’ve rotated though in the last 6 months. I’ll buy again, but not gummy worm flavor.

Arrived as usual no issues
