My wife uses it. She has a Hypothyroid problem and a recent check up showed her hormones were not right.
She takes 2.5oz every other day. Everyone is different. Her energy levels are higher and she feels "better".
Be careful which gel you use. Testim (originally given to me) is sticky for 20-30 minutes. It is terrible. I used gel, then went to shot therapy, new urologist put me back on gel. I think it is measured in oz. Can't remember if it is mg or oz, but the dr. will know.
Some side effects, again depending on each different person. Good luck.
Things could always get worse!! Sure enough, things got worse.
