Irish androsteRONE is human only as i have read the scientific liturere and so is androsteNOL so it seems that none is the only one in common although there are various forms that come under the sciecetific banner name \"None\" and nodays most of them use one version that is specific to humans and not the pig version.
The none nol and rone are simplications of a very complex science better ask james more on this one. At least SOE can be the only real product to say for certain they dont use pig none because it has zero amounts. Because it only contains androsterone and androstenol. If youre worried about that then buy that product. Also something like NPA and the edge have non androgens ingredients which are secret but enhance the product a great deal.
