when ending a 12 wk cycle,lets say a gram a week hypotheticaly, why wouldn't one start to cut back on the test lets say maybe for an extended 4 wks after the 12 wk cycle, maybe droping it to 500mg for 2 weeks than 250 mg for another 2 weeks than start pct? what i am trying to ask is why does everyone abruptly end there test cycle and go right into pct without tapering off? what are the pro's and con's?
