5-a-Androstenediol converts to DHT.
4-Androstenediol converts to testosterone
19-Nor-4-Androstenediol converts to nandrolone
19-Nor-4-Androstenedione converts to nortestosterone and estrogen.

These are all fairly low doses of each and I think the etiology behind this product is to get a synergistic effect from the combination of the 4 substances, but its a fairly ineffective combination, not to mention 19Nor-dione is to be avoided because of its estrogen conversion potentials.

All and all, there's much better out there for probably what this product costs, I wouldnt recommend it to anyone.

Thanks alot YJ for the very informative info. My freind takes 4 capsules a day
