    Pregnenolone (cream) + Test Cyp + HCG. Start together or not?

    @MarkM to prevent atrophy, I got prescribed 300IU 3x a week, and was told to watch for shrinkage, I guess if I delay HCG shrinkage can happen then (not fun). Pregnenolone was prescribed to raise noon cortisol a bit, since my cortisol crashes starting noon and all day stays low (8am is fine), so...

    Pregnenolone (cream) + Test Cyp + HCG. Start together or not?

    Why take Clomid if your E is already low?

    I took tablets (douglas laboratories). Now I was prescribed DHEA cream + TRT, we'll see how it goes. Clomid was not recommended (not because of Low E2, but because my LH is 6 on two separate tests).

    Why take Clomid if your E is already low?

    My E2 is very low naturally, and my LH is 6 multiple times tested. I guess it's indicates I'm primary and Clomid might be useless. At the same time I took DHEA for a few weeks, and my E2 raised two times, from 8 to 16. My Test stayed the same though.

    Please review bloodwork. Going to urologist tmrw. Hoping to resolve without TRT

    Philadelphia Penn Medicine urologist refused to deal with me unless TT < 300, doesn't take E2 into account, referred to an endo regarding low E2, and to a sex therapy for low libido.

    Please review bloodwork. Going to urologist tmrw. Hoping to resolve without TRT

    Had low T for years (less than 400 and even less than 300) But things got bad. Libido and erections were poor since this February, cialis and viagra don't work as good anymore (34 yo). Did a lot of bloodwork done (put together everything plus history one) in preparation for a urologist...

Understanding Your Hormones

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.
