Need some info on pct after Test E cycle

[bongzero]

I am currently on a test e cycle, and I am planning to PCT after my next cycle and stop anabolics copmpletely. But I will still take clen for a few cycles to cut. I would like to ask about how much muscle i can expect to gain and lose during and after PCT and if I can safely start using clen at the start of feb if I was to end my test E cycle early jan.
