We are of the same age Man. What a coincidence
I, too, mainly had issues with sexual issues especially in the arousal/libido department. I agree your total Testosterone is borderline low. Mine hovers around 440 - 500 and I feel it when it goes any lower. I noticed that when ever I manage to elevate my T to be 500 - 600ish and achieve a minimum E2 of ~19 pg/ml, my raging libido and boners would come back full swing.
Your free T is ok’ish, which means your SHBG is likely in a good range, but I feel that raising your T to 500-600ish range would be a game changer for you.
That said, I wish you had your E2 tested. Having high T with low E2 (i.e. < 19) never gave me back my sexuality. Using Clomid at 12.5mg EOD raised my T to high 700s but killed my libido. ANYTHING that lowers E2 while raising T never works for me, as simple as that.
It has to be something that raises both T and Estradiol to a good ratio. I suggest you test the following:
T, E2, SHBG, TSH, Cortisol
You can try 80mg/d Tongkat ali from brand Source Natural & 3000mg/d D-Aspartic Acid from Bulk Supplements for a week and judge how you feel. Combine that with 4x per week resistance training and quality sleep and enough calories (fat & carbs). In the mean time, steer clear from anything that lowers estrogen until you get it tested via sensitive assay.
