Took 25 mg ephedrine, 3 g d-aspartic acid, and a low-dose Cialis for good measure and got out the Bullmaster for an afternoon of pumping. Did this vid after 2.5 hrs at 3 hg-5 hg vacuum pumping. I am only 5'-8 and 160 lbs so I am amazed at the incredible size the balls can reach. The poppers definitely aid in the size increase while pumping and feels over-the-top!
