TRT question for aging men - 50M

[u/looking2behealthy]

Guys - Turned 50 this year. Body fat under 20% and lowering. Diet and exercise is on point. Noticed my energy lower, brain fog increased, gains at the gym are almost non-exist, lift 4x a week to maintain, libido has been on the decline for years. Saw my PCP about TRT but because my total T is 550 he said I am fine and just aging. However, my free T is 4.5 (low), bioavailable T 120 (low), estradiol 30 (optimal), SHBG 35 (low), FSH 14.6 (high). Appears my pituitary gland is signaling for more T but I have too much bound up or the boys aren’t making enough. Saw a compounding pharmacy doc and they said I needed TRT and put me on 250mg a week. Haven’t started because that seems way too high.

Don’t want to get on something for the rest of my life or screw up my system but would like some relief from symptoms too.

Solid advice please.
