This generic version of the medicine is very low quality. When compared to with the name brand (non-generic) version the different is quite obvious. I have also observed a difference from batch to batch, meaning that each time I order the same generic version there can be noticeable differences in the effects between the respective batches. Some batches have been better than others, although I have never received generic medication that was on par with the effectiveness of the name brand medication. Because of these inconsistencies and the poor quality medications this will probably be the last time I will order from ZipHealth.
