No way would I ever suggest taking THREE orals at once like this! There is no need. Thats like saying you have a headache so you are going to take Advil, Asprin and tylenol all at once. Each one would probably be ok on their own, but you are looking for some major issues, cycling like this. If you were to add winstrol 50mg ED alone to this cycle, for the next 6 wks, while dialing your diet in for fat loss, you could do really well. If you want to take it further, I would add in an injectable like masteron 100mg EOD, or if you are experienced, tren ace 50-100mg EOD.
If you were to do this, I don't see a big problem in running your cycle for an additional 6 wks.
