Hard to say...I'm only on day 4 but I feel great. People tell me it looks like I've tightened up a bit, especially in the mid-section.
One thing worth noting is that I am sweating like a pig at night. I mean to the point where the sheets are matted down and actually wet!! It really has me kind of concerned because this is way past the night sweats I experienced while I was doin Tren.
