    Doctors tell me I had a TIA . . .

    Boulder is 5,400 feet not 13,500 feet which is vastly different.

    Hip Replacement Surgery Experiences

    Absolute key is the surgeon you use. I have had both hips and knees done. Look for low infection rate and low return which is posted on some doctor eval sites. I found two in the states: one at Wake Forest and one at Cincinnati. I will tell you from experience that hip recovery is 3 times easier...

    The role of NO in the management of OA

    Had both hips 09-10 and knees done 17 and have had zero issues. Range of motion as good as or better than before. But I have exercised all my life and did pre-surgery exercises to strengthen my areas needed. The surgeon is the key. Repeat the surgeon is the key. I found two docs in the US with...

    Can Omeprazole- Acid Reflux Medication Decrease Ferritin and Cause ED?

    For me there is no other choice. I picked up Helicobactor Pylori when I was in Guam curtesy of the USAF and there is no getting rid of it. Yes you can dose your intestines every 5 years or more frequently with antibiotics but it comes back because you can't get into the folds of the intestines...

    Does TRT prevent age-related illness?

    I am 69 been on TRT since 2016. I researched TRT as much as I could starting in 2012 when I had prostate cancer. I noticed that my radiation treatments caused me to have night sweats and never had them before. From my research I was told that my T level would be impacted. Mine normal T level was...

    Acoustic Shock Waves: Does This Work to Improve ED?

    There are many other studies after this one and unless you are totally dishonest you can't cook the books on a double blind experiment. Look at the other studies which were below this one. It isn't a single source that is presented by the NIH article.

    Acoustic Shock Waves: Does This Work to Improve ED?

    Guys I found this study which 15 of 20 male patients improved significantly in erections. This was a double blind study. Details in the article. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3607492/ There are other studies below the first one I mentioned. This study was back in April 2013. This...

    Acoustic Shock Waves: Does This Work to Improve ED?

    I read that thread and it provides no evidence that this technology works. What is lacking is a study of men that use the device and those that don't. I think it either works or there is a placebo effect. I for one don't wish to spend close to 800 bucks for their device unless there is more...

    Acoustic Shock Waves: Does This Work to Improve ED?

    I have been seeing Acoustic Shock Waves being touted as a way to remove plaque on small veins in the penis. If you search on Youtube you will find a number of doctors and clinics that offer this service. As an engineer this seems to me as a focused ultrasonic. Ultrasound is from 20kHZ to...

    Gene's Nitric Oxide Stack

    I do and think it is coming from the pill form of L-Arg. I am switching back to the powder. Once I take the stack and head to bed there after a while later I have heart burn. If I use powder form L-Arg I don't. That is the only difference thus I know what is causing it for me.

    Gene's Nitric Oxide Stack

    I can give you my answer. I mix my powered L-Ag and L-Cit with POM juice about 4 oz and cold water. It works just fine and should be no downside to this. I am sure others will comment too. By the way the company DEFY which is a HRT company and more knows about Gene's Stacker. I am a patient of...

    Gene's Nitric Oxide Stack

    Nelson Thanks for the input. I do need to investigate other forms of getting Citrulline. I appreciate what you and Gene do for contributions to this forum. Today was an example of the results. My muscles were pumped for a good while after my typical workout and my vascularity is significantly...

    Gene's Nitric Oxide Stack

    As a subjective data point L-Arginine in powder form has a nasty taste. In pill form it doesn't because it is coated. L-Citrulline doesn't have a real bad taste. The combination of both (to me anyway) is worse than just the L-Arginine. Might be the suppliers I get the L-Citrulline powder from...

    Gene's Nitric Oxide Stack

    As I stated my T level is 696 with E2 28 and free T 10. All good results. Now with Gene's stacker which I continue to take and getting my T to around 700 my nocturnal wood is good and I can really tell at the gym post workout that my muscles are pumped. I have been unable to get this result for...

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.
