Waste of time and money. What's the point of putting all those hormones in your body then coming off and going through all that hell of feeling like shit and losing hard earned gains.
If you wanna be conservative then it is so much better to just cruise on low dose for a few months, and skip that whole "1 step forward 1 step back" process of coming off and doing pct
Whether or not PCT is useless is wholly dependent on what is important to the individual. For guys who run traditional cycles ("on" time followed by "off" time), PCT is helpful, as it helps preserve one's gains by more quickly restoring a normal hormonal environment. Keep in mind, not everyone wants to stay on drugs all the time.
In addition, not everyone who wants to be on TRT for life post-AAS. Some guys want to enjoy steroids without getting too crazy, build a decent level of mass, and maintain normal testicular function after their BB'ing days are over....and for those of who who think no one can build a decent physique when using the traditional "cycling" method (on time/off time), think again. Many pros from the 80's followed this method of steroid use...and we saw some great physiques back then. No, they weren't as big as the pros today...and the BB'r who follows this method isn't going to look his best all the time, but many great physiques have been built this way, including some of the best pro physiques from the 80's. If anyone thinks all the pros from the 80's stayed on steroids year-round, they are sadly mistaken. Many of them took considerable time off after competitions and even took substantial amounts of time off during the off-season. For an 80's pro, it was very common to use AAS only 6-8 months out of the year. This includes pro champions! Of course, some used more frequently, but generally speaking, taking time off was "normal".
So, anyone who says it isn't possible to build a great physique using the cycling method is flat-out WRONG! It has already happened an un-told number of times. Of course, genetics will play a signifiant role, as always, but if the ability is there, many guys can build an amazing physique with traditional cycling.
For guys who want to get as big as possible, don't care about natural T production/fertility, and are willing to take the health risks associated with year-round use (or close to it), then PCT is pointless.
