I developed all kinds of ailments that had to do with pain when I started using AAS, bottom line and this is only my opinion, as u get stronger through the accelerated gains that AAS provides for us, u start to lift more and many forge about proper warm-up and proper form, sometimes when u surpass ur prior records day in and day out in a frequent manner, u start lifting differently putting strain in a lot of different parts of your body that were virtually unused before, I doubt 200 test and 200 mast is in any way responsible for this, though Deca wouldn' hurt I would up the test dosage and the masteron though, just my opinion though! Good luck!!
