I think that is BS... which is why I mentioned it. It is "natural" for testoterone levels to be all over the place. Plus it is entirely normal for it to decline as you get older. Sured I'd love to have the same levels I had when I was 18, but just because I don't doesn't mean I'm "not producing enough". This is doping plain and simple. I'm also not producing enough red blood cells to do my best... better do some EPO. Bring on the HGH and Viagra!
