Divanil, icariin, and I3C have all been proven to work. I've never used AX, but I have used those 3 ingredients seperately as a stack... And they are my top 3 favorite supplements. You can google the studies if you don't believe me. The science says it's real and I've seen it work in more people than just me. Not to mention AX has other useful ingredients, including zinc. Perhaps you didn't adhere to a strict exercise routine, or maybe your diet was lacking...
As for the DTH, it's reported to work better with the older crowd. Which already has declining testosterone levels. Maybe that's why DTH worked well for you.
