    What's your favorite beet powder? Been seeing many advertisements for Superbeets

    I went through 2 bags of this. Never felt any benefit from it so I stopped. Might try it again some time. I suppose the only way to know if it is doing anything for NO is to buy some Berkeley test strips.

    I got those pressure headaches for daily Cialis as well, my doc said that he also got them. Very uncomfortable and they didn't go away for me, even at 5mg.

    Tadalafil(Cialis), how long to kick in?

    I don't mean to nit pick, but sildenafil (Viagra) under the name Revatio is FDA approved for daily use. The down side is that because of the half life the dosing is 3 times a day.

    Dr. Mark Gordon question...

    Well for me it is the fact that I'm doing worse now that my total T is over 800 than I did before starting TRT when my total T was 200. My body doesn't respond well to the traditional approach.

    Dr. Mark Gordon question...

    Actually I'm the wrong person to do that experiment. When I stop TRT entirely my total T drops to about 200 or less and I don't feel much different than when my total T is over 800. I'm actually intrigued by the idea of a low dose like 50-60mg/week. My doc suspects my androgen receptors get...

    Dr. Mark Gordon question...

    There is an LEF article where he is quoted as saying: "Gordon explains that conventional medical dosage for testosterone is at 200-300 milligrams per week, which he has shown is far too high! "For example, a typical 25-35 year old male naturally generates 4-10 milligrams per day, or 60...

    Boston Area Doctors

    Of course Dr. Morgentaler is a legend in the field. I don't personally know anyone who is a patient of his, but I have read that in general he does not like to use HCG (see NO HCG: Dr. Abraham Morgentaler, Dr. Rand McClain, and Jay Campbell??) and I also believe he is hesitant to use an AI...

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.
