I believe I have been on Dermacrine for 15 days now and I am feeling great. This stuff just puts me in a great mood after application. Overall I just feel great all day long. Strenght increases are coming in the gym along with some endurance increases. Sex drive is still up and going strong. My skin seems to be a little tighter also and I am liking that a lot. My appetite is still going strong also. Dont know if its the Dermacrine but I have been sleeping great. I still got two weeks left and I am looking forward to that!
