I beleive Zosert is one of the generic sertraline versions that are made in India. It is legal for a company to make sertraline and many other generic drugs if they do not use the original patented manufacturing process, so they stir up a new way to make the stuff. So Zosert is sertraline manufactured via a different process than the US Zoloft. That must anger the original Pfizer drug cartel! I could find only one report on "Zosert" which the person stated that the Zosert sertraline they bought online was weaker, but I do not know if they bought it through inhousepharmacy, so it may not be the same zosert.

You can also buy the original zoloft sertraline from Masters Marketing for far less than most online sources and it is certain to be the real McCoy.
