im not really sure what your asking brutha, but if your asking if you can just weigh out your powder for say anavar and take it, well you can! same goes for powdered ancillaries like u asked about, like say Nolvadex powder, sure you can measure out 20mg of powder on ur scale and just dump powder in ur mouth,
it would be a pain in the ass to have to do that each time you wanted to take a dose, so people like to make it in solutions, so they can just shake solution and take it ,
