I would seriously consider cutting out the extra protein, creatine and HMB. If for no other reason than just because you will not be able to take that kind of stuff at OCS. The creatine especialy though, because that stuff can do a number on your joints.
I wouldn't be so concerened with putting on "muscle mass", it will all be gone after a few weeks at OCS. All that running is really going to slim you down.
