Well if he's pretty good at responding to steroids yes he will gain well off of this. Don't forger proper training, eating and rest as well. I did a cycle similar to this except it was 100mg week less of the deca and gained pretty well. Like crazy said though test would have been a good addition IN CASE of deca dick but not everyone gets it. Proviron could be used as an alternative. BTW - 50mg ed is not needed. I did 50mg eod and got results.
