I personally love this product! Will always continue to use. Fast results but will advise to get some cardio in before or after workout to keep the fat levels minimum! I would advise to take 2 scoops per day for first 3 days then take 1-2scoop everyday after that depending on what you believe is best.

I swear by this stuff, I was a massive *** fan until I tried the muscle fuel anabolic and never looked back. I recommend it to my friends. Of course you have to put the hard work in and let this product do the rest for you. You will gain size, strength and even definition.
I take 3 scoops straight after my workout, and then two servings of 1.5 scoop spread across the day. That's nearly 1200 clean calories per day.
