For his fifth cycle, at 200lbs if he's lean I don't think 500mg. is too much. I would be surprised if this amount were dead on until the end of the dbol when he might even up the test to 750. This is all dependent on his past history though and what his typical cycles have looked like. The thing I was thinking though was if this is his 5th cycle and he is doing a year off between cycles then he probably hits the sauce for all it worth that one time per year. I know alot of guys who take this route, though I couldn't wait that long consistently, and get results like they were newbies almost evey time. Alot of the reason that this method gives them a little more latitude in upping the dosages b/c they have a fresh system and so long to recover. It is all gonna be based on his past cycles though, but 500mg with 30mg of dbol isn't out of the ballpark IMO atleast.
