Not true at all. Quite the opposite. For those recreational users it is generally accepted that the best practice is Time On + PCT = Time Off.
Nor is is true that all steroid users are destined for TRT. I know a lot of steroid users that use the above format, and consistently have healthy blood levels off cycle. They don't want to be on TRT.
As a TRT patient, I wouldn't recommend the process to anyone either. True TRT can be quite a lengthy process and often involves a lot of turmoil with ups and downs. I'm sure most of the other TRT patients here would agree with me here too. How do you know you're headed for TRT anyway?
You shouldn't lose too much of the gains if you properly PCT, Train and Eat. I would suggest those that find themselves in this loop of "Cycle, get big. PCT, get small" are too heavily relying on the steroids in the first place. Their diet and training is off somewhere.
Finally, your comment on the other compounds I disagree with. All of those compounds have their uses, it depends on the person, their sport, and their goals.
Edit -- Also, I would suggest reading through the TRT forum before committing yourself to it.
