has anyone used this? if so is it any good I can get this but I can't get Deca so I heard this is almost the same other then it is only 50mg and it is longer acting. My buddy said he liked it better then deca he said he got alot more harder on this then Deca. Any insight before I buy it and also what is a fair price. I can get it for 110.00 for 50cc.
