I am 23, I have always been small but I have been working out off an on for 3 or 4 years and been at it for the past 6 months. I weigh 127.5 and I can not gain weight. i have been 127.5 forever! was thinking about doing about 5wk cycle of test e 500 a week. would that be ideal to put on a little weight? I don't want to juice for any other reason then to just gain a little weight that I cant do other wise what do you guys think? any suggestions?
