I was very skeptical of ordering n2guard because it seems like most supplements out there are overpriced and under-deliver. However I must say after trying it this stuff is really really good. I ran blood work during cycle and my liver values were at 80 which is very high of course and normal in this situation. I ran n2guard for 2 weeks then retested and my liver values had dropped to 60. Although they are still elevated they are much better and I feel like had I been running it from day one my liver would have been in much better shape. Bottom-line this stuff works I will never run a cycle without it again!
