Please take some advice from someone who knows a great deal about the stuff, KEEP away. The majority of the time users experience the side effects of anabolic steroids without the muscle gains. You want to gain mass, then eat! I know this has been stated many, MANY times before. I know this is not much backing for evidence, but let me go ahead with my story anyhow.
Me, I had some good muscle gains when I first started lifting when I was only in junior high all the way through my senior year when my test levels were peaking. However, there came a time when my gains came to a screeching hault. Changed my program, but still nothing. Change ever different aspect of lifting many times, still no results. Looked at my sleeping habits, they were still good. Looked at the basic overall structure of my workouts, everything looked fine. There were no signs of overtraining. However, I finally discovered the problem area was my diet. For years I had been eating whatever I wanted, when I felt like it. I would skip meals when I was busy, trying to make up for those meals at the next meal. I was drinking way too many sodas (not diet sodas either), drinking little or NO water, no fruit consumption, no veggies, my protein intake was not nearly high enough, and my overall caloric intake differed each day GREATLY. Finally, I became educate on the importance of a good diet. I made good gains and had a good BFP (please don't shoot me) without a good diet. However, when my gains were non-exsistent for such a long period of time I decided to follow a structured diet in which I would get the right amount of Carbs, proteins, and fats, in combination with a daily caloric intake that would be sufficient to my moderate-to-slightly-fast metabolic rate. The results weren't seen in a week, or even after two. However, after a full month of actually following a structured diet my gains came flooding in again. I gained about 5 pounds in one month, with a calculated lean mass gain of about 1-1.5 pounds. My lifts all went up, and my body started looking a lot better. I have cheat days where I will eat a few fast food meals or may not be able to eat as many times throughout the day, but these are usually only about once a week, and are also usually only about 3 times a month. Trust me, diet is important. If you want muscles you will have to eat. Even if you are on steroids or andros your diet still dictates the composition of your body! Andro in combination with a good diet and training program would be okay. However, just getting on andro without even trying to eat more and making an effort work little harder is like building a house without a foundation. Without a foundation the house will fall.
Foundation= Diet and Hard work, without this all supplements are as useless as thorned toilet paper.
