What Steroids do, for you on a weight loss(cutting cycle) is stop muscle loss that usually comes with strict dieting, especially when using T3 or DNP neither of which you need to use if you only need to lose 15lbs. Dial Tone is 100% correct that Diet and Training are the main things to focus on. Currently I am on a cutting cycle and stalled with fat loss and lost some muscle, so My current cycle looks like this:
D-bol weeks 1-3 20mg day
Tren(fina) weeks 1-12 80mg day
T3 25mcgs day weeks 1-12
Clen Buterol 50mcgs day weeks 1&2, 100mcgs day5&6,9&10& week 12
ECA(ephedrine25mg/caffeine200mg/aspirin 5grains)stack 2xday weeks3&4,7&8,and 11.This is a good cycle for a male but very bad for a female.
For women the only really safe steroid is Anavar which I would not use without alot of research on your part start with the diet board and the women's forum and ask daisy and Velvett before using any AAS or ancillaries.
hope this helps?
