i think Activate Xtreme and Novedex XT is a good stack...
XT being an ATD. Personally, when I dose 3 caps a day, I get VERY restful sleep and recovery.
Activate Xtreme as a test booster is good.. it has the only real proven components. Zinc, Icariin and Nettle Root extract.
While DTP is not an AI, there's a lot of good feedback on it being a great test booster. I look forward to trying it
