Masteron

Any body have any experience or comments about Masteron with drostanolone enanthate 150mg, Drostanolone Propionate 50mg compared to regular 100mg dro prop? other than one being slower acting than the other, what other benefits does this have?
Also, Ive never taken masteron but ive always been interested in trying out this compound,but one thing i read about this is that it actually works as a form of a serm or AI? is this correct?

It is not an AI or SERM. It has a slight suppressive effect on estrogen, but not to the point that you should leave out an AI during cycle.

Just like test - masteron is masteron. Only the esters change.
