If that graph were litterally true then injecting every 2-4 weeks would result in zero test levels after 10 days. - Or at least base levels, which since you system is shut down, would be basically zero T after 2 weeks.
In fact that graph shows a strikingly linear decrease with time - so much so that I'm very suspicious. Of course I don't have the whole article in front of me and it is more than 25 years old!
PS. I'm not saying I have evidence for an exactly exponential decay. In fact, the very fact that we cannot come up with a decent amount of real data is somewhat disturbing.
