I am similar, but I am only 29. 8 years of oral/transdermal cycling an average of 2x a year has been kind to me.
Only time I have was trenavar for 8 weeks, and it took a long time to really feel right. Like 8-10 weeks despite 6 weeks of SERM usage upon cessation. I have used 19andro in stacks a few times and it doesn’t seem to matter; it’s just too weak. But trenavar, dienedione, tren, dienelone, Trest, LMG, nandrolone are all things I would only recommend to folks looking at blast/cruise sooner rather than later ultimately. DHTs conversely are the easiest - no aromatization to estrogens, which are what really get the HPTA shut down. 19-Nors still convert to estrogens at varying degrees AND act on the PR additionally, and they tend to bind hard.
I would bet a lot that the letro and arimidex usage is indeed to blame. Ralox, exemestane (almost no effect on lipids), lower doses of trest, trt amounts of test, and perhaps a touch of prami would be much easier on lipids.
