BEYOND RAW Concept X, Clinically Dosed Pre-Workout Powder, Contains Caffeine, L-Citrulline, Creatine, and Beta-Alanine, Gummy Worm Flavor, 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).

Favorite pre workout

I work out alot by a lot I mean 6 days a week and I will say this products taste is not the best but In terms of effectiveness it delivers a average amount of caffeine with double the amount of beta (this itchy stuff) and last for my whole 2 hour workout ... Hope this helps

I bought this thinking it would be along the lines of LIT & LIT AF since my wife and I love them and love the flavor. Even though it says it's gummy worm flavor it tastes horrible compared to the others. I realize it's a different style of pre workout but I thought I'd try something new since I couldn't find the 60 serving size anymore. Ended up requesting a refund and finding a new pre workout.

Arrived as usual no issues

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.

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.

BOTTOM LINE UP FRONT:. not worth it due to cost per serving. Better served with a lower priced offering and a good night's sleep the night before.OVERVIEW:For what it's worth I usually buy the more expensive brands from GNC and I didn't feel any noticable difference. I only tried this offering on a whim. It's pricey when you factor in the number of servings so for that reason I probably won't buy again. As someone who intently tracks workout intensity and sleep quality (Whoop band) I can say without question that the amount/quality of sleep you receive the night before has a greater impact on your physical performance the next day. Don't take my word for it. Pick a day where you plan to hit your recommended water intake, bed time, limit your blue light exposure near bedtime and cut off your caffeine intake after 2pm and plan your last meal at least 3 hours before bedtime. You will notice that even with water only you will workout harder than no doing those things and drinking any pre-workout. Since this review is about a pre-workout I have to at least say it's "good" but only about as good as everything else GNC offers in this price bracket. All the claims of magical ingredients/dosages might induce a change in the biochemical level but it doesn't translate into measureable performance gains.TASTE: I have the Sweet Tart flavor. If imagined water that was flavored like the Sweet Tart candy then that's exactly what this pre workout tastes like. I can't knock it because that's what they advertise. So from that perspective they get a 10/10. If you don't like the Sweet Tart Candy you won't like this.CHALKINESS: yes as others have pointed out it does seem to be more on the chalky side. My jar is nowhere near as bad as what some are reporting. The minimal clumps are easily broken up. I suspect the clumps are a result of the ingredients but more so due to the age of the product and storage conditions. They could have used multiple moisture absorbers to help alleviate this, but I still think it would have a tendency to clump.SOLUBILITY:since I didn't have much in the way of large clumps I had no issue with it fully dissolving when mixed with the recommended amount of water. No different than other "premium" pre workouts.
