I don't want to spoil it for you if you haven't read the entire series, but the answer is no, at that point in the series Adam had not been depowered. Suffice to say, the entire series is not a high point for Adam -- due to the writing. Adam's power levels and intellect fall well short of expectations, imho.
After you've read the series, feel free to check out the 2020 appreciation thread where we discussed Adam's portrayal in the series at length. There were also discussions in one of the Dr. Doom threads on the series as well, which might be worth reading to get the take from VVD's fans.
Edit: By "one of the Dr. Doom threads", I meant the various threads that covered each issue of the Dr. Doom series last year.
