I'm on DT 2010 right now. I've taken the first one and the new one is a bit more potent. I took the full dose (6 pills) of the original and I'm only taking 3 pills of 2010. I'm a bit edgier on this one too and it's definately got the sex drive and sensitivity up. But this is a bit of a double-edged sword because I nut almost annoying too soon now, which wasn't an issue before (probably too much info). The bottle says decrease dosage from 5-6 pills a day to 3-4 pills a day if you experience this, but I've never taken more than 3. Anyway, I've never taken Activate, but both Diesel Test are great. I've always hardened up and gained strength while taking them. I highly recommend them and would definately take them again.
