I'm new to this board and this is my first post but I had to chime in about the dermacrine. Just received my second bottle and I have to say that this stuff is good. I'm 47 and was suffering from the dreaded old age test deficiency and was even confirmed by blood work (about 300). Read about dermacrine on this site and thought I would give it a try before using androgel (which I tried before but didn't do much for me). After 4 weeks of using, it made a believer out of me. I am now going to start the second bottle with a little assistance from some Havoc for another 4 weeks and then finish off with some dermacrine sustain for PCT - post cycle therapy - .
