5-androstene-3B,17B-diol is commonly referred to as androstenediol. It is an intermediate in the synthesis of testosterone from DHEA. DHEA is the most abundant steroid produce by the human adrenal cortex. It has high estrogenic properties so you are going to want to use an AI with your cycle. I would either use aromasin at 10mg EOD or liquidex AI from n2bm.com.
It is also suppressive of natural testosterone production so you need to run a good PCT after your cycle. 4 weeks of the following:
clomid at 25mg/day
nolvadex at 20mg/day
HCGenerate ES at 5 capsules/day
n2guard at 3 capsules/day
You can get everything you need off sarms1.com, n2bm.com and ag-guys.com
