ok i am curious about this. say u have a source that has deca durabolin 400mg/ml and u have a source that has deca durabolin 250mg/ml. u can buy 2 bottles of the 250 and have 500mg and pull out 400 mg and it will be the same as the 1 bottle of 400mg deca right? or is the deca 400mg better, stonger juice? have some freinds that are telling me that deca 400mg/ml is better than deca 250mg/ml. same thing with test, he wants test 400. i ask him what kind and he is stuck on test 400 he doesnt belive me about test enth, prop and cyp. i say i can get u 2 bottles of test enth. 250 and u can run 400 ull just have a little left, but no he wants "test 400". just a dumb question i guess i was just confused.thanks
