Hope everyone had a good Thanksgiving . My question is . I recently purchased a couple of vials of Anastrozole from a well know source here on Eroids . Is it normal to have little flakes floating around in vial . Even after shaking the crap out of it . Is it still good to use . Whould it help ? if I used a blow dryer to heat up the vial to mix it . How long does this stuff usually last .
