Research Liquids, No Powder Visible?

[bigbedu]

Hi Everyone,

I just received some liquid levitra (vardenafil) and looking at the bottle i dont see any powder, as in it doesnt seem like a suspension. I have done research with liquid cialis and viagra before, and with both they had to be shaken up, and if allowed to settle a layer of the dissolved powder was visible on the bottom of the bottle. With this liquid levitra however, the liquid is completely clear, it seems there is no powder dissolved. What do you guys think?

thanks!

I think that it depends on the chemical, I never had levitra but I have a bunch of other research chems where no powder is visible.
