Optimal or not?

[JacksonMaxing]

I'm taking Dexmethylphenidate (Focoline). I have done some research that says that it suppresses your hungry similar to what Clav takes. I'm not sure if this is true or not, but I know that it has greatly suppressed my hunger to the point of which i dont eat in the day. It has given many different benefits, such as energy, focus, and getting me very lean. But this is my concern is that the fact I'm getting lean from this, am I losing a lot of muscle from this aswell as well, or is it more optimal to take it before the gym or just in the morning for the bloodflow benefits.
