Any done a 4wks on 4wks off cycling? I have read here about 6 weekers but what about 4weekers with short esters such as prop, tren and winny. I assume that in 4 wks the shut down and pct wont be bad as with a 12 weeker. I have down 3 cycles. 34 215lbs 5'10" lifting for years. Also what would you recommend for dosages if you are doing 4 weekers? Also, what type of pct?
