I used Nolva alone as a sole form of HRT for over a year. We did this because I used to get dizzy when I took Test Cyp...a side-effect that I did not experience from Nolva.
I felt pretty good on it for the first 6 months or so. After that, I started feeling really tired and unmotivated.
I had some tests done and found the following:
Total T, Free T, E2, DHT all looked good
HDL, Progesterone, and Pregnenolone were all low
Having low HDL can you feel like shit. My doc is not sure if Nolva directly blocks the Pregnenlone pathway (a precursor to HDL), but I got off of that protocol and am on a more conventional one of 100mg/week of Test Cyp (sub-q) and 500iu/week of HCG (also sub-q). Been feeling great.
In short, I felt that Nolva gave the numbers that most people look for (ie, Test, E2, etc), but some of the really important ones (HDL, Pregnenolone) were not there.
