Maybe I can shed some light on this. I've done a few cycles of 1-AD, IMO it works real well when paired with 4-AD.
Currently i'm on dbol, 30mg ED. I was taking 9 pills of 1-AD ED. It doesn not compare to dbol in anyway! Dbol is a monster and is incredible.
However, when I was on 1-AD and 4-AD the strength was great, I gained 20lbs during all those cycles but kept 10lbs). I lost most of my sex drive on 1-AD and took forever to recoop from it. If you're going to stay legal then IMO 1-AD is the best you can get. It will make you eat like a bear, and cause your eyes to feel tired. Stack it with 4-AD and your sex drive might live.
If I didn't have access to AAS then I would do another cycle of 1-AD and 4-AD. The Stength gains alone were worth it.
3 cycles of 1-AD @ roughly $150 a cycle = 10lbs of muscle for me.
