Other than roids
I've had my share of E, GHB, and K, and NU NU's (Renewnutireints). During Newy Year's Eve I dropped a total of 5 hits of E one every 2 hrs. from 10 pm to around 6 am. I was rolling so hard that my jaw was sore for 3 days afterwards from grinding.
Love the E cuz before I know it I'm hanging with a cutie and just cuddlin, nuzzling and everything else. Towards the end of a roll a like to snort a little pinch of K. If I know I gonna hook up w/a girl then it's E-GHB-and a little Viagra just for a boost
