"I have been on Depo for 16 years. It's effective! No kids! I started seeing side effects around year 6 which included a little facial hair. Around year 19 I gained about 25 pounds (I went from 120 to about 145) it's still so worth it. No periods and no cramps after year 1! I take calcium supplements and I lift heavy weights so along with getting bone density test-so far so good."
