Original Epi only for me. Methyl E was similar but at 50-60 mg p.day it still wasn't as dry as epi hitting it 4 times a day every 6 hours. Might have been a little more vascular on the methyl E, but doseages were high. Was it Havoc? Donnu but it sure as hell didn't help my gyno like one bottle of real Epi did, and it really felt a lot like Halo at around 75 mgs or so. Call me a hater but I'll be sticking with the real Stane for quite sometime now.
