    Is my ED physical, psychological or hormonal?

    Hey TB, I feel badly for you, but I think you've found your way to some very bright people here on the board - hopefully they can help out. I have shades of the same concerns as you. I'm older, 69, but am in good physical shape; also on TRT. I have only a limited response to Viagra so I tried...

    Aging and Testosterone dose

    Excellent question! I'm not sure of the answer but I'm sure somebody will come along that does. In the mean time you should include your age - you could be anywhere from 32 to 82 years old . . .

    Interesting injury

    That side was under stress as I was one arm rowing, what to me, was a heavier weight. I think I turned my head to look at the angle of my arm, to see if I was doing the exercise right. Then I felt a combination of pain and what kind of felt like an elastic band snap. Since then it's sore...

    Interesting injury

    Yeah, I sure don't doubt you there BB! Thanks for the reminder - I discover that my enthusiasm to lift is over-reaching my ability to be sensible . . .

    Interesting injury

    As always you guys are terrific, thank you Phil, excelnelg and Guided. I have had an ongoing neck problem the last 6 months as a result of an unfortunate accident. Obviously this latest issue didn't help it. I'm starting to feel that, as a 69 year old, I'm spending as much time with rehab...

    Interesting injury

    I often get great info here on weight training. I'm 69, started TRT a 15 months ago, and find that I can finally build up some muscle as a result of the increased testosterone. Great feeling. I'm training pretty hard (for me anyway, I was never particularly athletic); probably harder than...

    My trimix sucks, what strength should I have?

    Madman, your post has been VERY informative, dare I say the most relevant post for me that I've ever read on the board here. My mistake in thinking of penis blood flow is that I was thinking in terms of absolutes - that you need high pressure to completely shut off blood flow exit to build the...

    My trimix sucks, what strength should I have?

    Hey Madman, your memory that I got a penile ultrasound is impressive. That experience was a little disheartening. There was a significant fee payable for the test. The doctor came in, injected me, and said he'd be back in 10 minutes to do the scan. But, he was back in no more than one or two...

    My trimix sucks, what strength should I have?

    Hey guys, I'm 69, take TRT, and have been using the Trimix prescribed by a urologist, with a formula of 20mg/1mg/25mcg, for a few months now. It works, but not that well. After injection, I'll kinda sorta get a 6/10 erection which can then be manipulated by me to an 8/10, which isn't bad, but...

    Advice and next steps. 38 years old with 305 total t

    You can consider yourself fortunate to have the excellent commentary from the experienced members above, who are all, in my opinion, bang on the money with their advice. You don't talk much about your symptoms, other than to call them "the usual symptoms". You need to go back and question...

    Help identifying this arm injury??

    Wow, terrific help from a terrific bunch, thanks all very much. I've just read the entries and will reread everything to make sure that I'm not missing anything. Truthfully, you couldn't buy this caliber of help . . . Something also that's extraordinarily helpful, is to have confirmation that...

    Did I hit a nerve?

    I've never tried the shoulder, but I hear it works OK. Really the thigh for me is pretty good; I might hit a nerve once every few months or so. Feels a little like an electric current, but not super bad. Yes, you do get a bit gun shy after it, just get back on the horse. Make sure you're...

    Did I hit a nerve?

    What size needle are you using? I use a fixed insulin 1/2" 27g which works quite well for IM. I'm not super experienced, but I suspect that if you hit a nerve you would feel it right away. I've been injecting IM into the thigh for over a year now and once in a blue moon I will hit a nerve...

    Help identifying this arm injury??

    I'm 69 and have been taking T for a year and lifting weights for 8 months now. I like the board members here and hope they can help me with yet another problem. My left arm is my non-dominant arm and if I'm looking at it with a straight arm, palms up, the pain is at the inside crease, but near...

    American men are hungry for injectable T: A legion of new health clinics are serving it up

    I'm 69 and started TRT just last year, largely because I would fatigue easily when exercising or doing physical work; it has helped me that way. As a younger person I would have my T tested occasionally, and it was on the lower side if not actually considered low. I prefer to be humble, but...

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.
