great for mass bro.....I reccomend it...It reacts to people differently though. YOU might get shut down...or you might be like me..and gives you crazy ass gains w/ no sides...good luck..
You are on Sust alone??? All the time? Have you tried Test? I have always had best results with Test. Last cycle I stacked with Deca and did get the most gains as far as weight. I gained about 20 lbs. I would try Test before anything else though.
