The other day we went in to buy some 1-AD from Capital Discount Nutrition in Oak Forest, IL. Well the owner is pretty cool and he usually gives us the straight on what works and what doesn't. He said that BPX is much better than 1-AD in that it's not a precursor or something like that, i can't remember exactly what he said.
According to this website
http://www.thesavagefighter.com/Store/Pro_Hormone/BPX.htm BPX has 5a Androstane-3 17b-diol 50mg
and 1,4-androstiene-3, 17-dione 50mg
Are you guys familiar with either of these?
Thanks
