Gen sys labs, should solutions of tamox/aromasin be white?? Please help!!

I know that tamox/aromasin are both white powders but just want to make sure that this is normal.

I got these two compounds from Gen sys labs, and I just want to know they're legit. Also the HCG I got has chinese labels.. good or bad?? Comments?

Another thing, when I do finally try to get the tamox/aromasin out of their little vials with a pin how do i correctly dose it since the compounds aren't 100% dissolved?

Obviously I'm a first timer, and am not in any rush but really want to get this sorted out.

Thanks for your time in advance!
