1 - with food and water
2 - here's a link.... see if you find your dbol here
http://www.steroids.com/Dianabol.htm

3 - no, it's not a good program at all.
here are the reasons:
a) even though I'm a low dosage advocate - 5 to 10 mg/ day would simply surpress your levels without adding any benefit. (keep in mind a very short half life of dbol - spacing 10 mg evenly would be ineffective at all, spacing 5mg - is a pure waste)

b) test fluctuations will exsaggarate SE if your'e prone.

c) if 15 mg is enough for you to grow, it takes 3 to 4 weeks to get actual physical results - thus, your best case scenario would be the following: you will bloat for 2 weeks, then lose the water. The muscle gain will not sustain without PCT.

d) Even if you keep low dosages - such prolongned use could damage your liver.

IMO
