How can i make my biceps really big, really fast?
Well that is an open ended question. Depends on what you look like man and your body type really. If muscles got big fast then every one would have them. I guess you could use roids but it still takes work and i dont suggest it. You can help make muscles appear bigger faster like this. When you work out do heavy weight of 5 to 8 reps and 4 to 5 sets. It is up to you how good your form is and how hard you try. Only use heavy weight you can handle 5 to 8 reps with a slow to medium controlled pace. Also you can take creatine. This should help you get that less defined cut muscle and more that bigger bulky muscle and the creatine helps the muscles retain water which makes them appear bigger and is safe to use.
