Hey guys don't know if anyone can help or not, however here's the problem. I feel tired a lot latelt don't really know why, it's been a little while now tho' and it doesn't seem like any change. I'm 31 been lifting again seriously again now I guess for about 2 years. I'm supplementing with Diesel Test Hardcore for about a week b4 that it was Drive/RPM stack for a month. I started megadosing vitamin C a week ago to see if that would help I've always supplemented with it tho'. Also I've been taking Reset A.D. to see if that would help I've been taking it for a month also. I've recently started to wean off caffeine I tried cold turkey and got unbelievable headaches. Don't know what to do. Any suggestions? Should I hit the Dr's?
