It will take 2-3 weeks for the test e to wear off, depending on your body. I prefer Clomid too, I do 50mg at bedtime after 2 weeks off and 100mg at bedtime beginning at 3 weeks off for a week. Then 50mg nightly the final 2 weeks. I've never found Nolvadex(Tamoxifen) good for bringing back natural test. Be sure your diet is good for natural test production as well including Zinc.
