Again I have no knowledge of this subject, but common sense say tapering is not necessary because you'll be going from supra physiologic levels to high normal levels. A taper might make sense if you were going from crazy high levels to way below normal levels. AGAIN, this is just a guess.
What will you do to control the E2 during the blast?
Also, will you really gain much size on a blast that short? How many times can you get to the gym in 6 weeks? 18-24? That doesn't seem like enough time to really grow much.
