I did enough research and still can't find a solid answer lol. Friend of mine told me Clomid is by far better. My source also told me Clomid is a lot better and nolva would affect my gains. He just said words like what you guys are using lol, don't understand shit. He told me to try Clomid one cycle and Nolva on another ... he swore I'll keep more gains with clomid and keep my protein high.
Of course there are my other friends who like nolva better cause Clomid have a lot of sides.
