Hey Scooby, I would just go with the test and like you said.. watch your diet... you might gain some weight but if you are eating right then you will gain 'muscle weight'... EVERYTHING starts in the kitchen, EVERYTHING you put in your body makes a difference. Eat clean and eat 6 small meals a day make the meals count ! when you gain muscle you are basically turning protiens into dense muscle mass.and make sure you get plenty of rest , muscle grows while you are sleeping. good luck man... id do some Anavar as well it will help you with the weight issue... remember ... this is a lifestyle and it takes a lot of time! it doesnt happen over night! Slow and steady wins the race my friend and also remember that steroids just helpp you assimilate protiens, you still have to put in the work bro! Good Luck
