njmuscleguy's cycle was something like:
Wks 1-10 test enth 750 mg/week
Wks 1-8 deca 600 mg/ week
Wk 11 (off)
Wks 12-14 HCG
Wk 12 liquidex
Wks 12-17 nolva
I went to this site and plugged your AAS parameters in:

Your cycle is modelled like this:
Drug: Testosterone Enanthate
(Initial) Dose: 375mg
Half-life: 7 days
Dose Frequency: Every 3.5 days
Cycle Length: 70 days
Start Day: 1
Tapered: No
Drug: Nandrolone Decanoate
(Initial) Dose: 300mg
Half-life: 9.5 days
Dose Frequency: Every 3.5 days
Cycle Length: 56 days
Start Day: 1
Tapered: No
This is a chart of your androgens blood levels during and after the cycle, day by day. Notice how it took a couple of weeks for the long-acting esters to build up in your system. Maximum levels were reached around day 42, six weeks into your cycle! The purple line is deca, and you can see how it trails off early (because you stopped deca two weeks early), but trails off slower than test because it is longer acting than enant. The red line is enant. Where the line turns blue is the point where the steroids in your system have declined to a lever lower than your normal test levels would have been. But your test levels are suppressed from the cycle, so past the blue area is where you are andrigen-deficient. This is where you need to be doing PCT. In fact, I would do HCG before the blue line starts, and start the rest of your PCT about one week before the blue line (running an AI or anti-E with the HCG).
On the chart, the blue line starts at day 91, which is a full 23 days after your last shot of test, about 3.5 weeks after your last shot of test and about 5.5 weeks after your last shot of deca. That is the point in type where your steroids are no longer really affecting you.
I would concoude you ran your PCT 1-2 weeks too early. Because of the high doses you used, the majority of your PCT was done while high levels of androgens were still in your system. It is best to time PCT so most of it overlaps the time when androgens have already left your system. So in your case, I would do a second PCT if your T levels are still low.
By the way, this is exactly what happened to me. Long, heavy cycles of deca require a long wait, in the range of 3-6 weeks after the last shot depending on dose, before starting PCT. Otherwise the PCT wiull be too early and innefective.
