I beleive yates cycled his AAS 6weeks on, 3weeks off in the offseason. Not sure about contest time. The reason i think he cycled 6weeks on 3weeks off is because when Ian Harrison was asked if he got the idea to cycle his AAS from Trevor Smith that way. Ian said Trevor got that idea from himself(Ian), Dorian Yates, Kerry Kayes, etc. Ian also said all the pros he talked to cycled there AAS that way with an androgen/front load for the first 2-3 weeks then fast acting ester for the rest of there cycle.
