Why are you ramping down the dbol instead of just running it straight through 4-6 weeks. IMO i would run either the deca, or the tren, not both. If its strength your looking for I would run the tren and I would bump up the dosage.
I concur, Cycle is a bit "all over the place." I realize you have put yourself on a 10-week time restraint, and obviously it may have been better to start it further out from the competition, but it is what it is. Deca and tren compete for like receptors, so probably don't need both, unless you are using deca for it's anti-inflammatory effect on joints. If that is the case, 200mg will give you the same effect. Also I see no need here for dbol
and winny. Dbol is great for strength by itself (A-bombs even better IMO). Also, I would run the tren all the way through.
Week 1-6 dbol 50-75mg per day
Week 1-10 Test e 750mg per week
Week 1-8 Deca 200mg per week
Week 1-10 Tren a 100mg eod
Good luck.
