It  depends on your sex. For males, I would go with 50mg ED for a first cycle for 8 wks. For females, start with 5mg ED for 4 wks and then if you want to increase, go to 10mg for 4 more wks or remain at 5mg if you are getting some good strength and pumps. Remember for girls, the least you can take and still get good results, the better off you are! For females no PCT. For males, you will want to do a full PCT after
