I trust
Novedex XT at the beginning of a cycle as a mild anti-estrogen. I don't know about
6-oxo...In the matter of 3 weeks on a DBOL only cycle(25 mg per day split in to 2 doses) with Novedex Xt (2 pills mid-day and 2 pills before bed) I gained 3/4 inch to my arms about 10 lbs total and I never developed gyno or acne. After the 3'rd week however, I switched over to Nolvadex because more firm research has been done with Nolvadex. Definately would not use Novedex XT or 6-Oxo for pct though. Hope this helps...
