better workout program on cycle?

I am going back on bulk gear cycle soon and want to try out a new routine. In the past i have done all these variations but i feel the best was still 1 body part a day. But i was all natural that time, now with the gear i want to try somethign new. Last cycle i did #3 and it worked well...
Haven't tried any other while on cycle.

Main goal: chest/delts/biceps/ mass
Least concern: legs
