MET-Rx NOS Pumped, Nitro Punch, 16.9 oz. (12 Count), Pre-Workout Ready to Drink (RTD) Sugar Free Energy Supplement with Caffeine, and Amino Acids for High Intensity Workouts

Taste wise, if you ever had grape cough medicine as a kid, it tastes like that. I tend to associate cough medicine with being sick so it's personally not an acquired taste for me. A friend of mine loves the taste so I just gave the 11 that's left to him.Effectiveness. Similar to a 5 hour energy drink, but diluted: you get more in terms of quantity but works the same. So instead of taking a shot; you can sip on it and take your time, or gulp it down in one fell swoop.It's sugar free with no artificial coloring (clear in color)Nothing much else to say; just a diluted 5 hour energy drink that tastes like grape cough medicine

This stuff has a sort of chemical fruity taste to it that you have to get used to. Not to be gross or anything but if you drink one of these I would not be to far from a bathroom because at least for me and the few other people I know that have drank them they had to run to the bathroom no more than 15 minutes later after drinking this. I am not sure if it is because of all of the caffeine in them or some other chemical but it works really well as a laxative for that is for sure.

Easily the best tasting pre-workout drink I've ever tried.The bottle is supposed to be consumed halfway 30 minutes prior to your workout , with the rest being consumed throughout the course of your workout. I tried this method and found myself not finishing the bottle because I didn't stop to drink enough of the remainder to finish the bottle. I would recommend drinking more than half and finishing the rest as you workout or drinking all of it and drinking water during your workout. My workouts are 30-45 minutes long and these bottles provide more than enough of a "kick" to get me through. I'd guess they would hold up for an hour's worth of exercise.

I was very impressed with this drink, from the flavor to the effects it provides The Blue Raspberry is my favorite flavor, and is far superior to the grape flavor that I previously reviewed. Unlike other pre-workout supplements, MetRX didn't give me the feeling of being jittery or anxious, but rather gave me sustained energy throughout my workouts. I felt that I was able to accomplish much more when using this supplement than without it, especially when working out early in the morning. I would not recommend using this product during late night workouts however, as the effects can make it quite difficult to sleep afterwards. Overall this product exceeded my expectations.

I like to drink these about 20 minutes prior to a long run or bike ride. Might be in my head but it sure feels like I have a bit more energy and can go a bit further than without. small improvement on taste would be nice. Not a bad taste but not the factor that will keep you coming back. I understand these are not about the taste but performance though.

I love the flavor, but I go to the gym at least three times a week, with my dad. Unfortunately that’s at least 6 bottles a week. It’s kind of expensive so I have to settle for pre-workout powder + water.

Was happy to get some very cheap for like $3 per case. Thought it was good for a try, but now I love this stuff. I love the taste. I like that it is clear with no need for colorings. It makes me feel energetic, but not really jittery. Just my speed. No mixing required is a bonus too. May be tempted to pay full price when my cheap supply runs out as this is way better than my powders.

I’m so surprised at how much this has increased my workout performance. It doesn’t give me a nasty caffeine buzz, tastes good, convenient, and doesn’t have bubbles like a soda or energy drink. Looks like water, tastes like Kool-aid.
