It feels like my lips are about to break out, I am trying not to scratch but this is painful. I am so upset. I am in class and embarrassed. What is in this drink that is doing this? I have never experienced this with any other energy drink in my 40 years. Please, please stay away from this drink.

Cellucor is respectable Great customer service and good products. I've only tried 1 of the 2 products that I ordered, but so far I am pleased. Also, I was assisted by support staff within a reasonable time (I think I submitted my inquiry after hours) and they answered my question(s) concisely.

Do not order product from Amazon Do not order product from Amazon. Mine came in smashed, neither Amazon nor Cellulor would help me with replacement.

Great taste with diabolical energy! I bought this product as I was developing a tolerance to my normal pre-workout. The first time I tried it I just automatically used 2 scoops as this is what I use with my other product... COLLOSAL mistake! I had to quit my workout 20 minutes in because I felt as if I would puke! Next time I just used 1 scoop and had excellent results. The pins and needles feeling was quite intense compared to my other product, however it is not something that bothers me. I love the taste! It's not bitter or chalky. I will definitely continue to use this product.

NEVER again! I'll be looking for a new product! I ordered about a month ago and didn't realise whatever I did would have them ship another one. I got ahold of them 3 days before it shipped when I seen an email saying it was going to. They still let it get shipped when I said I didnt want it and now I also have to deal with an overdrawn bank account and to ship it back to them. Makes it even worse that whatever they changed in their c4 ripped makes me nauseous, Which I've taken it for MANY years besides the last one because I was pregnant, And I've never had a problem but now, not a good experience. It doesnt mix well anymore, taste REALLY disgusting now and had me puking! So why would I want another one?!
