You may have reviewed medicine profiles and tales claiming that a weight gain of 40 pounds or additional isn’t really unusual with this medication. Since the beginning of this website, and as long back in time as this author can keep in mind, we have not spoken to someone in Mexico that’ve really gotten that much from this steroid alone.
