halodrol 50 is a mild steroid.
it is already active when it enters the body which is what a steroid is.
pro hormones arent active yet, going through one conversion to become test.
things like dhea go through 2 conversions, and by that time its only good for old ppl anyway.
from the way you posted and the info you posted, personally, you have MUCH more reading to do. i'm not going to down you doing it, but i will say do your research and know what you are putting in your body. know all the outs and ins. know what will go wrong, how it can go wrong and how to fix it if something does in fact go wrong.
