Different Levels of Aromatization in Test E Cycles Over Time

Has anybody had changes just within a couple years in how much their body aromatizes testosterone? I did a cycle a couple years ago of 500mg/wk of test e with ~1/3mg of adex the morning following each pin. I cruised through that cycle amazingly, with no sides.
My current cycle I’m past the halfway on, I did 500mg/wk for the first half(8 weeks) and 900 for the 2nd half (8 weeks). I tried taking the same amt of adex I took last time and could feel my e2 levels dropping, with achy joints and lower libido. I backed off for the rest of the first half and felt great. I tried adding a slightly smaller amt of adex back a couple weeks ago for the 2nd half but am feeling lethargic, achy shoulder joints, low libido, etc.
I’ve accepted that I need to lay off the adex m, but I’m just wondering if anyone else has had a similar experience? I don’t understand how there can be such a dramatic drop off in aromatization in just a two year period in between cycles.

Yep. When I started TRT I was pretty fat and took up to 3mg of anastrozole a week at one point. Now I’m blasting 480mg (just bumped it up) and take .75mg a week.

With UGL test there is always the chance that your stuff isn’t dosed consistently. Unless you made it yourself

Yes, same experience
