Next, you move on to Fenugreek (Testofen)...and this ingredient SUCKS!!! I know - not very scientific of me; but it's the truth. This goddamned thing is HIGHLY estrogenic and you couldn't get me within a 10-foot pole of it in any products I design. Testofen is in quite a few products on the market; of which...it draws upon some data. It is just an extract from Fenugreek however standardized to contain about 50% fenusides. This is important because you NEED a down-regulation of the number of the following saponins: diosgenin, yamogenin, gitogenin, tigogenin, and neotigogens; which are all previously purported to be sources of fenugreek's estrogenic properties (makes sense seeing they are phytoestrogens, but remember to take phytoestrogens and divide by the number 5 to get contribution to total estrogen cotent). The "positive" studies are essentially from 1 group of researchers (i.e. - non-replicated).
