2011 when I started working out , I want to challenge myself and beat my limit. I bought every workout supplement I found interesting cause of their magnetizing advertisement. Everything is effective and fine until Dec 2012, I exceed one recommended dosage of this preworkout supplement - "BSN HyperFX". (this will make you beast in the gym) One dosage is equal to 250mg of caffeine but I took 2 1/2 dosage (that is equal to 600mg of caffeine = 6 cups of coffee) w/o eating bfast and the worse is I didnt workout after taking it ( You need to sweat when taking this preworkout) After 3 hours I started to feel different, dizzy, like Im having goosebumps all over my body. Im panicking coz I felt somethings going to happen like Im going to collapse or die. I took BP and its 160/100 something like that. Thats the first time I got high bp in my entire life. It all started there. 2013 it happens everytime. High BP (170 is the highest), palpitations, nervousness, tension headaches etc. My nervous system might have breakdown from the caffeine overdose or supplements Ive took before. Chemicals are still in my body and my brain but doctors didnt find any physical problems at all. They conclude that these chemicals affected my brain fluids forcing me to think anxious etc. In short, anxiety disorder. Since that time I've stopped working out. 2013 I'm like dead. My body consumed lot of meds like Benzodiazepine etc. My body weight dropped. 2 years I spent in working out became worthless

This will always be my all-time-favorite pwo for bulking season! While the taste isn't something to be desired, and you have to stir it with a spoon....it puts you in the "zone". Throughout the month I took it, I could notice the difference in my overall strength and how easily I could throw weight around. I recommend that you have a big cold glass of water to chug after you drink it because your mouth will be on fire and you will sweat big time throughout your lift. BIG FAN!

Favorite Pre for years. Two words FOCUS and Strength!

I bought this item 20 days ago. Tried few pre work out drinks like C4. The taste is nice but sometimes the product really hits. You are ready, focused, eager, pumped to hit the gym and sometimes it does not give you any effect. but the price is very reasonable so i would s****est this product as it does not have creatine in it which results in water retention

On days when I'm training fasted and need a kick in the pants, I add about 1/3 a scoop of grape BSN Hyper FX into my grape BSN aminoX BCAAs. 1/3 a scoop is 5 calories and <1g carb, so it doesn't jeopardize my fast.

The taste is aweful. If you can get past the taste, the kick out of it is minimal. It takes atleast 45 minutes to kick in and after that the pump lasts for about half an hour.

Clean energy and no shaky or jittery feeling. Good for late workout so I can sleep at night.

This has to be maybe THE WORST pre workout I have ever taken. I only got it because it was free with a tub of Syntha-6 I bought. Which I am NOT a fan of either. I think BSN is garbage for the prices they charge and absolutely poor quality from such a known company. I am VERY displeased in this product, as I work 9-10 hours a day before my training and need a boodt most of the time, this barely did the trick to even get me motivated to lift anything. Shame on you BB.com and shame on you BSN

I've only tried one other brand (on amino acid), this isn't as good as far as energy and pump, I did like the flavor and fizz.

Didn't really work for me and I'm sensitive to supplements. I like the tingle from other pre-workouts and this one didn't have that. This was part of a by 5lbs Syntha-6 get Hyper-fx for Free, so I wasn't losing out on money by trying it. Also, mine was missing the scoop! So I had to figure out how many grams were in a teaspoon to accurately figure out what a scoop is. Overall I was not impressed and ended up giving it to my 18yo brother in law. On to the next one!

Doesn't taste too bad, better than NOs Explode. But I don't feel anything after taking it.

The flavor wasn't too good, and I was not a fan of the carbonation that was in it. As for energy, I didn't notice much. Probably wouldn't buy this again.

Was one of my favorite Pre's until they took the D-Aspartic acid out.

One word. FOCUS.

I have a relatively slow metabolism and this product didn't give me the pump or physical charge i was looking for. this product did give me the endurance and mental focus i was looking for. i was able to complete my work out and do most reps i was shooting for. the fruit punch taste is just god awful.
