Yea mdpv is a drug all in its own, I don't think it needs to me mixed with ANYTHING however if you willing to except the come down (have something for it) MDPV and GHB is one of the most insane crazy combos EVER. However I gotta warn ya trying to keep up with the MDPV and GHB at the same time is tricky at best, and at some point you better have something to make you sleep or you will regret it beyond anything you have ever felt in your life.
