most of the youngs seem to think it's dumb for older folks to even consider PEDs
Stupid people parroting stupid shit. The first thing the doc wants to do with us "older" people is put us on pharmaceutical drugs. So why would it be "dumb" for us to use pharmaceutical drugs?
A lot to unpack here.
You lost 100lbs in 18 month and want to loose another 30 but you don't want to be skinny (after the 30lbs you will be 170lbs) Are you under 5'5"?
Your estradiol and SHBG are to high but your test is pretty good.
Your calories are to low but I guess if you are trying to look like a 170lb runner your OK.
Your recovery is slow, based on the DOMS you feel.
You have a stash of PEDs but have not put them to use yet due to being in the "research phase" but you have talked with a TRT clinic.
You are currently on an upper lower split, 2 on one off with weekends off.
I hope I got that all right, some information was a little mixed and confusing. Here is what I would do.
I would get on TRT with the clinic to learn how my body converts to estrogen and how to mitigate this issue.
I would get my Test levels to around 1100, add 3iu of HGH, and increase my calories to 2500 (1 gram of protein and carbs per pound of body weight minimum) a day split into 4 meals to help with the recovery.
Increase my workout frequency and push past the DOMS.
Since I was already doing an upper lower split I would shift to 2 on one off repeat.
I would do this for a year consistently then move onto putting on some size.
One thing I have found out about doing PEDs at an old age is I need longer cycles and bigger doses. Think 20 weeks and 5mg of gear per pound of body weight. If you taper up the doses lets say every 4-5 weeks until you reach the 5mg per pound of body weight, your blood work should not suffer and you should have almost no side effects. But everyone is different.
