I have taken this product several times and have found the more I use it the more I have gained in both size and strength. The only thing is that my most noticeable gains have come when I used its "brother product" Rezzerect. This is a plus because the two are very effective together. A huge minus goes to the fact is that for both you'll be spending over $130, that is ridiculous.

Taste (8/10): There are at least 4 flavors, I have tried 2(lemonade and watermelon) of them. They were both really good without being too strong. Every once in awhile when drinking, I would get a strong sweet sensation, but you get used to it and it still tastes great.

Effectiveness (7/10): Again I have found the more I took this product the better I felt and the bigger/stronger I got. Unlike products like Jack3d, I never had to take another scoop or increase the scoop because I always noticed the increased energy and focus while taking it. But like most people have said, the effects will vary from person to person.

Overall: This product is worth trying out at least once to see if the effects you get are better than other products. Buzzerk is very effective making a noticeable pump, increased focus and definitely more energy. The price is the only thing that is even stopping me from buying this product repetitively. I even get nice discounts because I know a guy who owns a Complete Nutrition.

Conclusion: Buy it once to see the results. If you don't like it don't buy it. If you like it, make friends with the store owner and get products cheaper.

Have taken many PWO .. and this rates average (to me). I know supplements vary in their effects with people, but this product was way to expensive for being just average.

Had to ramp up to two scoops very quickly to get any effect. Thus far Jack3d has been the only PWO supplement that gives a bang for its price.

I have tried quite a few differnt PWO since 2006 and this product by far has worked great for me. I have noticed to get the desired effects I had to use about 1 1/2 -2 scoops. Compared to other PWO this product is a bit expensive, being a college student I am always looking to save money on products But I took a gamble with this one and it was worth it for me, but I am unsure if I'll be able to afford it when needing to restock. The using of Buzzerk has increased my pumps, stamina, and muscle mass. I have recommended this product to both friends and people at the gym. All that purchased it which has been about 15, saw similar outcomes. Buzzerk is all and all a great PWO

I got ahold of some coupons for Complete Nutrition, and I thought I'd give them a shot. I was a newbie with supplements at the time, and BUZZERK was a terrible mistake. I felt a little something the very first time I took it, but after that it was all downhill. It didn't give my a buzz or high energy at all. I hate to be harsh and I recognize that different products/different creatines work better for some than others, but this is just my personal experience. Kre-Alkyln just isn't for me.

Mixability (7/10): This product mixed well for me in a shaker bottle, but there were some particles that floated around that would not dissolve. It didn't bother me, but the texture could freak some people out.

Taste (5/10): I tried the blue razz flavor and it was only so so. It was kind of chalky in taste and if it's not mixed well enough, all of the sour flavoring will sink to the bottom. So it was chalky at first and extremely sour by the time you get to the last drink.

Effectiveness (1/10): I honestly did not feel anything great with this product, nor did my lifts increase in weight. I felt all right after my first try, but after that this was worthless to me.

Value (0/10): This is my biggest issue with this product. It was ridiculously expensive! There are honestly better supplements out there for better prices that offer better overall results. The tub is pretty small and the price will rob you.

Overall (2/10): I was just disappointed in this product. I didn't buy this so it would mix well or taste decently, I bought it to better my workouts and it failed to do that miserably.

Everyone is different, so my advice is to try various PWO products to see what blends work for you. However, I would not recommend this product to be one that even deserves a chance. If you want to try Kre-Alkyln, then go elsewhere. Also, the salesperson will do whatever it takes to sell this junk to you. Avoid it.

Tastes great and the pump is more noticable than the energy rush! Great first preworkout supp for a newby but eventually you want to graduate to anothe CN product Blitz which is by far the most effective workout product I have ever tried! I now look forward to leg day! Enough said.

I gave this preworkout a low rating strictly cause of the price but I have to say it was a well rounded product.It gave me good workouts and i liked it but i only tried it cause I talked the store manager into giving me a free bottle. at $70 per 30 servings its a complete rip off. Powerlab's MASS Pump is very similar to it but it costs less than $40 at Saveonsupplements.com so thats what i use and like .Superpump Max is another ok product I would use over Buzzerk.

If you are making six figures a year try this stuff out, for the rest of us try something else.

hey guys this is my first review, so bare with me if its not completely perfect.

taste:10/10 the taste of this product is actually quite enjoyable compared to many other products i have taken, i have the crimson crush and would recommend this product to those who are looking for a good tasting pre-workout.

price:6/10: I have finished a tub of this product, and will probably not be going back for another, just because of the 69.99$ price tag. I got it with a deal because most of Complete Nutrition's prices are not set in stone and can be negotiated.

effectiveness:7/10: I am a guy who likes to get a lot of lifting done when he hits the gym, so i use a preworkout that can last me the whole time i am there. lets just say this product does not do it for me. The only reason i would recommend this to someone, is if they have another product they would like to stack it with( in my case Cellucor's c4) to add some extra kre-alk Creatine and flavor to your preworkout.

all and all, a decent product,better stacked with others, but maybe worth 25-35, even 40$ at max, but definitely not 70$.

I take NX6 with Buzzerk 30 minutes before i hit the gym and by the time i get there i feel like if i don't start lifting something that i will just go crazy. These two together will make you go nuts at the gym.
1 hr to an hour and a half straight lifting followed by Rezzerrect another Complete Nutrition supp mixed with 100% Whey then 30 mins of cardio will have you feeling good the whole day.
I also advise taking a multivitamin (of course that goes without say as I feel everyone should take a multivitamin daily)
Buzzerk is an amazing pre workout matrix i got a sample from one of the guys at Complete Nutrition and took it as directed (30 mins before workout) and i felt a rush of energy like i felt like i was going to turn into hulk so i went to the gym and had the best work out of my life i took it with NX6. after my sample was gone i went to the gym and had ok workouts but i always had Buzzerk in the back of my mind so i went and bought it. Although it is a little pricey the pumps energy and overall stamina is well worth it. I now take it every time i go to the gym and I cant even think of going with out. I love this product along with the other ones i mentioned and if you stick to these with a healthy nutritious diet and kick ass at the gym you will love the person you will become.

Before using this product I had yet to find a preworkout which was good tasting. This stuff is like kool-aid. Energy, pumps, stamina all good. I paired it with a product called NX6 though, so the pumps may have been accellerated. It was a little expensive, but for the quality of product its worth it.

Is high grade stuff,one of the best Ive tried,in the top 3 at least.Way better than GNC's namebrand stuff.Cardio and heavy lifting,very clean also.Will be buying another container of this stuff,I would take up to 2 scoops of Black Powder,this Ive havent had to up the dosage after a whole container,usually Im upping it after a week.
