    BPH and nutrition

    Madman, the unwanted gastrointestinal side effects are not all I've experienced with Beta-Sitosterol. It immediately taps into my workout horsepower and it does not elevate sexual function as one reader claimed. I lift and do taxing cardio/heavy bag work daily and it is noticeable, it seems all...

    Can anyone recommend a urologist who offers the ejaculation sparing techniques for enlarged prostate surgery?

    Too Many Red Blood Cells or Platelets Stall Blood Flow in Cerebral Capillaries

    Thank you Nelson. I donated today. Two more questions, what do we call "donating too frequently", and, I get up to pee 2-4 times per 8 hour night due to the prostate thing, is that creating something similar to a sleep apnea situation? I go right back to sleep, deeply, dreaming frequently. Even...

    Too Many Red Blood Cells or Platelets Stall Blood Flow in Cerebral Capillaries

    I am fifty-eight. Been on TRT (cypionate only, 100mg every 5-6 days) for 14 months. I take 10mg Cialis once a week. My hematocrit was 41 when I started TRT and bodyweight was a lean 160 lbs. My hematocrit has steadily climbed to 54.1, weight now at 180 lbs, lifting more and liking it. Doing less...

    Does anyone use Nandrolone (Deca Durabolin) ?

    Nelson, I used nandrolone decanoate at 200mg/week for 8 weeks when I was 29 (1990). I did not use anything else before, during or after that. I had some acne, felt great, and gained some nice upper body muscle as my friends and I lifted fanatically. It did give me slightly less hard erections...

    TESTOSTERONE ONLY, NOTHING ELSE.

    Does taking a little too much negatively affect sexual drive, desire and performance?

    TESTOSTERONE ONLY, NOTHING ELSE.

    I have begun TRT, started just over 5 weeks ago. I started a protocol of 100mg cypionate every 4 days, that's it, just like the thread says. Which averages to 175mg/week. Things have been fine but the past 2 weeks my erection quality has vastly slipped. There has been a great deal of life-stress...

    The benefits of long term use of Cialis

    Gentlemen thank you. Without this forum I'd be playing around with trial & error and going down dead end roads, probably all the way to the whistle. There are some good men at the gym, but I think some are sticking with their old bodybuilding protocols, not the TRT approach. They're big, pumped...

    The benefits of long term use of Cialis

    Thanks MM and Nash. I will start the cyp at 100mg/wk when the time comes. As for training I agree. It's either strength work, or combat skills/lungs, every day. The subject of Cialis came up, and it apparently has some amazing qualities. I think MM mentioned not having too many products working...

    The benefits of long term use of Cialis

    Thanks Gene, I think my urologist will write me a script. He was very cooperative about writing the TRT (he went with 100mg Cyp/week). I have not started the TRT yet. What daily or EOD dosage do you recommend? I am 57 and erectile issues have just begun for me. Last year at 56 I did not have...

    AT 57, ATTEMPT TO INCREASE NATURALLY OR PULL THE TRIGGER?

    Thank you Vince. In September I had a lab test TSH of 2.590, but no other readings were requested. I guess you still would recommend the full panel. By the way I feel OK, not depressed (even though the sun has disappeared for the next 4 months) and I love the sun. I can workout fairly hard and...

    YOUNG MAN HAS TUMOR? ON PITUITARY, LOW T/ENERGY/BRAIN FOG

    A young man I know has been told there is a small growth or tumor on his pituitary gland and that explains his symptoms and his abnormally low testosterone production. He has been put on 200mg Cypionate/week and feels much better. Jay Campbell mentions a very routine procedure for the the...

    AT 57, ATTEMPT TO INCREASE NATURALLY OR PULL THE TRIGGER?

    My 57th year is a big step down from how I felt at 56. Been reading a lot on optimizing endogenous production, i.e. fasting, avoid alcohol/sugar, good oils, sleep, intensity, avoiding soy, etc. But I don't want TO BECOME FRAIL. At this point I can still train, arthritis isn't stopping me yet...

    TESTOSTERONE ONLY, NOTHING ELSE.

    Is it possible to administer weekly injections of cypionate, at some optimal dosage, and not include HCG or AI's? In other words use testosterone only.

    Important when using T and not feeling good

    Are thyroid levels looked at as part of standard protocol when a 57 year old with a 450 total testosterone begins TRT with a firm like Defy?

    Has anyone ever regretted TRT?

    Mud, I like your response here, Im just turning 57 and things are different this year. Last year I was still grappling and sparing with amatuer fighters. Fall 2017 gave me a spinal injury so I laid around through the winter and now Im working out hard but the horsepower isnt there and a bunch of...

    LIVING IN OVERREGULATED UPSTATE NY-HOW DO I GET LABWORK?

    Hello, Im new to TRT. Trying to find out how this Labwork gets done. I live in upstate NY, and it sounds like there are problems with prohibitive regulation. Driving down to Scranton PA would not be a big problem. Will a lab in PA honor a script from say Defy in Tampa? "Dont tread on me"...

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.
