First of all if you did any research at all you would already know that masteron won't do much mass building. It is generally used pre-contest for hardening, etc. But since you've been searching I'm sure you already knew that :whip: I just hope that your immense laziness isn't a reflection of your overall work ethic, because if it is you won't make a gain if you pump 3 grams of gear a week into yourself. Now that I've got that off my chest, I'll recommend that you do some research and choose which Test you want to use for your cycle, you haven't done anything in 4 years so Test would treat you great unless you lack discipline in the gym and in your diet. How tall are you?? Maybe make a goal to get up to 170 lbs before gear, most on this board would recommend much higher but if you insist on juicing, you'll have to know what excersizes make you grow and what type of diet you need to pack on some mass, once you know that then you'll be in a much better position to make the most of your cycle. Hope this helps.
