I don't know what sort of effects you are looking for. Massage probably wont directly make you stronger, and would have even less to do with helping you bulk up.
It is great if you have hypoxic/ischmeic tissue, trigger points, fibrotic tissue...basically any sort of soft tissue dysfuction that is hindering proper movement and mobility. It can work to clean up the soft tissue. For most people, it is very relaxing, which can help aid in recovery between training bouts and potentially even decrease some muscle soreness. In addition, one study looked at some positive effects that massage had on salivary immunoglubuilin A in athletes engaged in extensive cycling training - this may be helpful for keeping us healthy and preventing us from getting sick when training hard.
