I was on for about a year when I came off for fertility reasons. I essentially used clomid e3d at 10mg for just under 18 months. Never came off clomid though so I'm not sure if I would have ever rebounded on my own. I did an hcg protocol before coming off, then just clomid and test boosters. I STRONGLY recommend taking 5grams of ashwagandha 2.5% withanolides. I added it in about 9 months after I came off, the difference was night and day. My test levels were normal (630), everything was in range, but I just never felt "normal" when I came off. The ashwagandha helped tremendously IMO though, psychologically and hormone balance wise. Best of luck
