I took to trobalt for a year. I was very careful and had my eyes monitored by an ophthalmologist. It helped my T greatly while I was on it, and when I tapered off of it my T didn't bother me as much. I had no long term side effects (that I know of), but some people on this forum have.
I guess my answer would be it depends on the likelihood of side effects, but I'm less likely to take risks now than than 1-2 years ago when I was desperate for relief.
