Eod Winstrol (winny) injections is fine. Yes, Winstrol (winny) does have a short half-life but ed injections are NOT mandatory for gains, especially if this guy is relatively new to AS cycles. Is that the case? If so, I would recommend Eod injections at 50mg's at 1 injection of Deca per week of at least 300mg's.
Like Stonecold said, 200mg's of Deca will only shut him down. Test Prop Eod at 100mg's would also be a good complement since it's a fast acting ester, whereas Deca takes a minimum of 4 weeks to kick in. I don't know about the whole "frontloading" of Deca idea.
