to start off with, only a fuckin idiot would have a debate over wether sustanon or winstrol is better for mass. and probably one who never used either. or bothered to research about either. and dont hate on bros who wont admit to using. it is illegal and socially unacceptable. didnt you know that if you inject gear you are liable to flip out and go on a killing spree? well, thats the general public opinion. so when you get around to using, you can go ahead and admit to it to your neighbors, co-workers, your boss, in laws, and whoever else you would like to, and hopefully they will all still accept you for who you are and not judge you for what you are on. i will keep my business to myself. what am i on right now? yup, you guessed right. creatine, protein, and pro-hormones. okay, i will tell you the truth. im on sustanunya 250. peace.
