If you have ethylestrenol, my advice is toss it or sell it to your gullable friend. It's a waste. If you must use its, remember that the gains will be next to non-existent. Using 30-50 mg per day for 5-6 weeks on end, stacked with other products are the best way to go. Make it worth your while and add in some testosterone or boldenone for example. Aromatization is minimal, so the use of anti-estrogens will not be needed during the cycle, but because 19Nor steroids are nasty, suppressive stuff, you would do wise to run HCG and Nolvadex or Clomid once the cycle is over.
