C4 Extreme Reviews

Ok where to start with this one. It is without a doubt one of the most known pre workouts on the market right now, but does that really make it the best? Lets start the overall breakdown of ingredients first.

Profile(taken from
Beta Alanine 1,500mg " 
Creatine Nitrate 1,000mg " 
Arginine AKG 1,000mg " 
Explosive Energy Blend 741mg " 
Vitamin C (As Ascorbic Acid, N Acetyl-L-Tyrosine, Caffeine Anhydrous (135mg), Mucuna Pruriens, (Standardized For L-Dopa), Bitter Orange (Citrus Aurantium)(Fruit), (30% Synephrine), (Advantra Z®), Niacinamide, Folate (As Folic Acid ) , Pyridoxal 5-Phosphate, Vitamin B12 (As Methylcobalamin )

Ok Beta Alanine is very popular in pre workouts now a days as it should be, it does help simulate nerves as well as giving you those sweet tingles. 1.5g is an alright amount but usually you do want to go north of 2g here. Creatine nitrate is a newer form of creatine which is fine since it does not upset the stomach and will help with cellular energy. Arginine, oh arginine you would be so awesome if only the liver didn't breakdown about 70-80% of you before being absorbed. If you want a sick pump look for something like citruline since it bypasses the liver and leads to greater arginine production in the body. As for the famous blend, alright amount of caffeine(135g), niacinamide to help with blood vessel tone and mucuna pruriens to help with some focus.

Here is the thing with c4, if you take the 2 scoop dose then you actually get a pretty good pre workout out of this, minus the pump. The focus is nice and the energy levels stay up most of the time.

If you take my recommendation of doing the 2 scoops you are looking at about $2 a serving which is not too bad but could be better.

Pretty typical pre workout blend here with beta alanine, arginine, and caffeine but nothing super special. The 30 serving, or 15 serving if you are doubling up and you really should be if you want to get clinically dosed levels of most of the ingredients makes the $30 price point a tad on the high side. Overall I would say this is a very average pre working.
