I think the tendency, as far as PCT and recovery are concerned, is to focus too much on hormonal restoration. So, things like liver health, and perhaps more importantly lipid health, get overlooked as a result.
The problem or risk with taking a "SARMs require less hormonal recovery time between cycles" approach is that if you do this regularly, you end up spending most of the year with jacked lipids.
What kind of damage is this doing to your arteries? What kind of strain on your heart?
Any of these compounds we run, no matter how harsh, mild, or supressive, can negatively impact lipids.
So, as arbitrary as the equation may seem, the bro guideline of "cycle + PCT = time off" works out pretty sound IMO. If followed, it generally permits 2 cycles per year. As far as lipids are concerned, Id say that is a good maximum, especially if you dont get bloods done.
