The only 50cc bottles I've ever seen were Winstrol V,Equipoise and Finaject and that was middle 80's...I personally like the idea of the 50cc bottle..That way there you have a large quanity of it so I personally tend to use more and gain more....I've never heard of deca in that quantity and the only reason a power lifter would ever think of doing deca is for joint pain only...As far as a power lifting drug deca is completely useless....It takes to long to get anything out of it and the gains and the amount of time to get something out of deca is a complete waste of time.....Now if you were going to cycle and then get off and stay on a small amount of deca while your in the so called cleaning out phase till you started your next cycle...I'v e heard of that,but I just don't like that way I feel you have to clean your system out for at least 8 weeks...Be carefull it sounds like it could be fake gear....
