Im currently skinny as hell 6'2" about 170 lbs. I made some improvement from 155 over a few months, and have seen a little more mass and muscle definition form. All i have been taking is whey protein,but now want to try some nitro tech. Do you take this and also the whey protein? Also is this stuff any good? I have read some good reviews,but wanted to get your opinions before purchasing. Im looking to gain another 20 lbs at least and add more mass.
