agree, 20mg e/d of tamoxifen should be plenty. 12 weeks isn't very long so you don't need to use all your 5 vials. You can get 10 shots with 1 vial. Mix 1 vial up with bateriostatic water then using a slin needle take 500iu every 4 days(store in fridge). So you want your last shot of hcg to be taken on the same day as your last shot of test. Wait 2 weeks,then start your pct of clomid and tamoxifen.
