Now are you talking prohormones like m1t or are you considering coming over to the dark side with AAS?
What is your friend taking? What works for him may or may not work for you. Everyone is different. To gain 15 pounds of lean muscle and lower your bf to 6-7% is going to be extremely tough. Personally, I would focus on a high colorie diet (with a supplement of choice) to bulk and put on muscle and then diet down to your ideal weight of 175.

Well the dark side would be most preferable. But my ablitly to obtain has come at a high price and a hard lesson learned. I was smoked by an lifter at my gym. And its not like I can go a tell. I was thinking of prohormones because I can get my hands on them. Also I am in the military I know of people the do it and I also know some that got caught. I don't want to risk my future. My bud is going to take M1t and some tribex. I just don't know if it will work for me. I know gaining weight and dropping body fat is hard but that's my long term goal. I would be happier with sjust adding the weight. My job requires me to run some much that I can never gain.

Firstly, how youre diet? and youre training?
Im guessing youre diet sucks and you dont get good protein e.tc in??
Getting to 175 wont be a problem if you fix youre diet and training.

Well my diet does kinda suck. I have to eat at the chow hall. I take meal replacements threw out the day so that I can try to get in 5 meals a day. I also have protien on hand and take that in between meals. I take a multi vitamin and that's it. As for counting calories its hard to say because I don't prepare my own food.

Diet is so key man. It took me a number of years to realize it. As soon as I cleaned that up, my gains sky rocketed without supps, and exploded with the extras!!!!
