I think there is no official indication that there are permanent side effects but to me it sounds rather unlikely that there are none. You cannot stop your body from growing either, that would be the discovery of the century, and while you can suppress puberty by blocking some hormones produced in your brain, your sexual and other organs probably don't develop normally. At some point they will stop growing forever. Anabolics were steroids that were used to increase performance in sports since it works similar to testosterone. Here it was the other way around, more hormones got administered, and people did have a very large number of side effects later in their lives and had to pay for it significantly. I am no doctor but pretty sure that a doctor that flat-out denies the possibilities of such side effects aren't good ones either. Discovering them is a long process, so careless administration of such drugs seems irresponsible. If there is no clause for exclusion for side effects I would seek litigation.
