Do you know how long upregulation typically takes?
Why would CB cause a temporary spike in T and why only temporary? If you're thinking it takes up T's place in the receptor, thus causing more free T, which then leads to more E, it's DHT that binds to the receptor in absence of CB, not T. And, again, if that's the reason, why would the increase in E from T be temporary?

You mean more easily observed in medical studies generally or in CB studies? Because if you mean the latter, I'm not sure anyone was looking for it.
