I've done a 800mg first 2 weeks and 400mg for the remaining 10weeks only cycle of EQ with Proviron at 50mg/ed for the last 6 weeks. It was the first cycle I had done since the early 90's. I actually was really happy and retained most my gains. You have to be patient, but after 3.5-4.5 weeks it starts to kick in. Hardly any water retention and weekly gains, awesome pumps! It can really increase your appetite as well.I have heard that it stays in your system quite some time after discontinuation. So watch out if your tested!
I would do it again in heart beat, speaking of heart beat, it really helped me with aerobic capacity. So if you are hitting the cardio hard, lifting hard and eating alot of clean foods, you can really change your body composition over the course of 3 months or so. You still need to consider recovery though
