First Ostarine Cycle, what to expect and any advice?

Hi, I am about to start my first mild ostarine cycle on 10mg per day for 8 weeks. I am 21 years old, 6.4 and currently at 87kg.

First question I have: Will I need PCT if I only stick with 10mg and if yes which one should I go for.

Otherwise, what do you think can I expect (Gym 6x a week and all calories tracked, on a lean bulk right now) and do you have some key advice for me, for example from your own experiences?
