    Low SHBG, scrotal T cream increased DHT, drove E2 to <2

    My SHBG has run in the 12-15 range with pretty much any TRT changes I have made.

Seemed to work, and a set of labs found DHT was...

    Hcg prior to vacation absence

    Going away for 8 days,(not a cruise) I currently take Hcg 3 x week. At 200iu per dose = 600iu/week. I decided taking a break while traveling might be good, but I have a question about the last dose. Thoughts? should I take a slightly higher dose, (then won't take another for 8 days) on the...

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
