If you have enough HCG to start from wk 1, that is fine. If you want to wait a few wks in, that is ok too. As long as you are running it within a few wks of having started, it will have the same effect for your recovery, IME. As for your AI, I would start it from the first wk you begin the cycle. Long acting tests can take seveal wks to build up and begin showing muscle changes, but from the moment you inject your first shot, your test levels are increasing!
