    New Doctor. Put me on HCG monotherapy for secondary hypogonadism

    I wouldn't call it a requirement, but I've read from a few sources that men supplementing exogenous testosterone simply have lower fat "needs" than men who don't. Perhaps I've been misled though. I will try to fetch some of the sources. Thanks for the reply Nelson, what's your take on that?

    New Doctor. Put me on HCG monotherapy for secondary hypogonadism

    Wishing you the best on your journey with monotherapy. I'm almost to the 1 year mark and feeling good as ever. Numbers quickly went from 139 ng/dL to ~750-900 and have stayed solid. I wanted to ask a follow up regarding HCG monotherapy as it pertains to nutrition. I have read that men...

    HCG mono with good T response (849) but symptoms only 50% better

    I can't speak for Jimmy, but for me, yes. I had a sperm study to see if I was even fertile in the first place because of pituitary hypofunction and it came back fine, so we're doing our best to preserve it

    HCG Monotherapy, should I stay on it?

    Would anyone be able to offer a subjective comparison of HCG monotherapy vs Testosterone + HCG? I am hesitant to switch being that I've shown so much improvement in less than 6 months on HCG alone. But if the consensus is that I might "feel" much better at a given level on TRT/HCG rather than...

    HCG Monotherapy, should I stay on it?

    Thanks Chris. I really appreciate the detailed response. I've seen a few doctors: a urologist (with experience in andrology), an endocrinologist, and a neurosurgeon. The urologist is running the show, and he is clearly the most progressive of the bunch. He cares deeply about how I'm doing...

    HCG Monotherapy, should I stay on it?

    Cheers guys, I'm a 22 year old male, recently found to have very low testosterone (139ng/dL). Doc prescribed Clomid, which got my levels up (to 600) with no symptomatic improvement (seems like the norm with Clomid unfortunately). I've been prescribed HCG at 4000 iu/week (daily injections)...

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.
