    TRT Peaks and troughs or steady levels. Which is correct?

    I only responded to oral testosterone. Turns out I didn’t need it. My original health problem was T2 diabetes, which caused iron and vitamin D deficiency. The treatment was TRT! I don’t know how TRT is supposed to correct iron and vitamin D deficiency. If anything, TRT is going make the iron...

    Normal Total T/ lower end free T

    What’s your diet, height and weight? Do you exercise on a regular basis? Do you get 8 hours of restful sleep every night?

    Good Total T with Low Free T.

    If you’re serious about trying to fix your hormonal issues without TRT, which I do recommend, I think you might try the carnivore diet. I started two weeks ago and I’ve already lost 7 pounds while changing nothing other than what I eat. I sit for 40 hours a week on my full-time job and work...

    I find that when my ferritin levels are low I don’t sleep well and considering TRT lowers ferritin….

    Good Total T with Low Free T.

    You’re severely estrogen dominant. If your C-reactive protein marker is elevated and you use the standard non-sensitive estrogen test it’s going to show a false high value. What’s your height and body weight? Any supplementation, vitamins, minerals, medications or hair loss drugs?

    The holy Grail of nutritional research regarding red meat consumption and lack of evidence of harm.

    I’ll just eat more steak and keep my body in a state of ketosis. So far the mental benefits are amazing. I put my T2 diabetes in remission in one week without TRT. My glucose levels are static, pre and post meals.

    Tight or knotted muscles from TRT?

    TRT can cause you to burn through vitamins and minerals, better do a complete vitamin and mineral panel. Your problem could also be an inappropriate injection frequency.

    The holy Grail of nutritional research regarding red meat consumption and lack of evidence of harm.

    Results: The HP group improved their reaction time significantly compared with the UP group. Branched chain amino acids and phenylalanine in plasma were significantly increased following the HP diet, which may explain the improved reaction time. Conclusion: Healthy young males fed a HP diet...

    The holy Grail of nutritional research regarding red meat consumption and lack of evidence of harm.

    The two largest-ever NIH-funded, multi-center clinical trials (the Women’s Health Initiative and the Minnesota Coronary Survey) where saturated fats were either reduced or replaced by unsaturated fats, on nearly 54,000 men and women, concluded that saturated fats had no effect on cardiovascular...

    Thinking about TRT and could use some guidance

    The fin is lowering your DHT, which is responsible for libido and well-being. The fin is cutting it down. Never take a drug your doctor prescribes without doing your own research! The drug makers of Fin lied to everyone, including the doctors.

    New to TRT. Received first labs. Concerned and need help.

    Testosterone typically lowers blood pressure and cortisol the stress hormone.

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

    Testosterone deficiency isn’t defined by Total T. I was at Total T 438 and Free T was deficient. Total T is a function of SHGB, the higher, the SHBG the higher the Total T. You don’t have to be below range on the Free T to experience symptoms of low testosterone. After you start TRT and...

    My Experience On Jatenzo (Oral TRT) Log

    I just got my iron panel back. Before I post them I’m going report. I’ve never felt better. You’re going to cringe at the results. Ferritin 7, iron 27, iron saturation 6%, total iron binding capacity 426, hemoglobin 12.9 and hematocrit 40.1. Vitamin C has been deficient the last 7 to 8 months...

    Recently started TRT in MA, would love some help understanding first labs

    You’re still in the TRT honeymoon phase, the libido should drop down somewhere closer to normal in due time.

    New to TRT. Received first labs. Concerned and need help.

    What other symptoms? The majority of members included in a pole/thread I created felt better with higher than normal testosterone, 68% to be exact. If your SHBG is low, there’s nothing you can do about it on TRT. SHBG, regardless of the level shouldn’t be your main focus for your symptoms.

    Possible high estrogen symptoms from my injection.

    I am four weeks into my Jatenzo restart, I felt really good the first week, like crap on and off the second and third and started feeling better the fourth. I reached a steady state within the first seven days, but my body is still adapting even now. You’re three weeks in and a long way away...

    TRT Dose question

    I thought you found success with 50 mg once per week.

    AI & E2 rebound effect?

    I stopped TRT for a week so the rebound was nonexistent.

    starting injections soon a little nervous

    You thought wrong dude. You realize this forum is mostly littered with men and their failed treatment, right? All of those success stories you’ll never hear about because there’s no need to seek help on a forum if you’re not having problems.

    starting injections soon a little nervous

    Just inject 30 gauge insulin syringes in the shoulders/deltoids. I hit too many nerves going in the thigh. If you can get on oral Jatenzo/Kyzatrex, do it.

    Blood panel, how's mine look?

    Leg strength is linked to longevity. So if higher testosterone dose gives you more strength in your legs…. I have 50% more leg strength with above normal testosterone. You talk about using AI’s, I need no such intervention. I guess it comes down to genetic lottery.

    Blood panel, how's mine look?

    That’s what it is, a theory. No data saying above normal testosterone is unhealthy. Some people are just more conservative but that doesn’t mean they’re the authority on the matter.

    Iron overload

    Supplementing 100 mg of vitamin C sent my ferritin levels over the normal ranges. Stopping vitamin C supplementation has seen my ferritin levels below range. I’ve always felt better with my iron saturation 14- 16%, ferritin low and iron bottom 25% on and off TRT. I also feel better with my...

    Androgel and blood test

    In my experience with oral testosterone, which has a similar half-life to the cream, five days LH and FSH start increasing. This is when I start to feel my testicles to start aching.

    High HCT low iron

    There’s currently no data the proves high HCT leads to heart disease, stroke or health. COPD and hemophilia lead to high hematocrit, but is the disease that causes the clots and damage.

    Blood panel, how's mine look?

    I didn’t respond very well to even twice weekly injections. The higher the dose frequency the greater the response for me. I now dose twice daily, Jatenzo.

    Switched from Testosterone troche to SQ shots, feel horrible now.

    Try to imagine being in a drunken stupor only that doesn’t come close. Some have called it an inflammatory response. I think it’s much more than that. I would compare to marijuana use, the way the brain is fogged up. Amplify that 100 times, throw in some drugs and high percentage alcohol.

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.
