Sorry, I don't know, but if it helps, I first read about it being used to treat kids on high dose corticosteroid thearapy. It's a good deal because you only take 50% of the normal dose since your using EOD, but the adrenal suppression was delayed much longer than would be expected, and the benefits were greater than 50%. I used Dbol like this as a teen and had good results, taking only on w/o days.
meathead1987, morning dosing and w/o is the best for avoiding suppression. I always have better w/o in the evening though, so I can't say how much it matters for gains.
