Wow, Charlotte, and I'd thought mine seemed high after my second blood test!
When I had my first blood test my testosterone level was also 0.1 and then when I had it re-tested 3 months later, after using Testim regularly, one tube every 8 days, my testosterone level was 4.4 and appeared on my results in red.
So, we used the same amount daily over the same period of time but your levels rose to about 4 x my levels. Strange, especially as you haven't noticed any effects. I at least did have increased energy and a libido again, however I also began to lose more hair and my skin was quite greasy. Like you, I'm now making a tube last me twice as long, i.e. about 16 days.
