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

    I will continue to advise newcomers coming to this site with problems that a low-and-slow approach is preferred, backed up by scientific and anecdotal evidence. If you're going to keep butting in with contrary and harmful advice that is unsupported by any serious evidence then you can expect...

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

    You can repeat this misinformation forever, but the study does not compare physiological to non-physiological doses, and therefore does not support your claim. The fact that a particular dose is tolerated in a short-term dose-response study does not indicate that it is suitable for long-term...

    Which works in this fantasy world of yours where you can only choose between 125 mg/week and 50 mg/week in one dose. As I implied, there's plenty of evidence that physiological doses are safe and effective. It's up to you to prove that non-physiological doses are better, especially because you...

    Less estradiol with faster-acting testosterone?

    I wouldn't expect enanthate to be much different from cypionate on similar dosing schedules. But it's perhaps harder to evaluate propionate if you're not measuring area-under-the-curve. Are you saying your E2/T ratio was the same? The limited propionate data I have also doesn't really support...

    Less estradiol with faster-acting testosterone?

    Just putting this out for discussion and comments. There have long been anecdotal suggestions that faster-acting testosterone leads to lower overall levels of estradiol. In particular, it's often claimed in regard to using testosterone propionate versus longer esters such as cypionate. It could...

    Ask yourself why we even have reference ranges. They are used to diagnose and treat disease/dysfunction. The dysfunction is clearly associated with levels above or below the range. I hope you aren't claiming otherwise. For all the supporting studies you claim to have, all you can do is return...

    Testosterone Cypionate vs Testosterone Undecanoate

    Really good advice here. Going from TC once every two weeks to TU is like going to the opposite end of the spectrum. You currently have this enormous variation in serum testosterone over each two-week cycle, with troughs being something like 10-20% of peaks, and peaks likely over 1,000 ng/dL...

    It's refreshing to see some marginally clever pushback interspersed with the usual inanities. Unfortunately it falls short, because fitness is good.

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

    The burden of proof clearly is on you with the extraordinary claim that non-physiological levels are better for overall health and should be the default starting point for TRT. As I went through your list of references it became clear that you had not read them and were relying on a faulty AI...

    In real life men thrive on physiological levels of testosterone. Think the current president @ 441 ng/dL. On TRT some men get away with higher levels, while others suffer side effects and come here, as you well know. What would I do without your incredible wisdom? Maybe I should eat right and...

    I'm not sure what you're referring to. I don't recall even expressing an opinion on the prevalence of this side effect. I did tell you that TRT had the opposite effect on me, with higher doses being somewhat sedating and demotivating. The side effects of excessive testosterone that I've...

    Thyroid Labs for Dixiewrecked

    I'm not saying this applies to you, but I went down the thyroid rabbit hole with Defy and now think it's a case of treating the side effects without looking into the underlying cause. I had top-of-range reverse T3, which they treated with a T3 prescription. It brought down rT3, but didn't seem...

    How quickly they forget. After this point-by-point examination of your references you didn't even attempt a response. https://www.excelmale.com/threads/trt-other-medications.32780/post-300919 All this study shows is that being hypogonadal is somewhat worse than being mildly hypergonadal...

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

    If you recall, I dismantled every one of your purported references. Not one refuted my claims. You basically relied on one study in which no subjects experienced physiological levels of testosterone throughout each injection cycle. Meanwhile, you continue to defend the indefensible: that a...

    Hey everybody.

    It's important to have a good idea of free testosterone. Many of the existing tests are inaccurate and even use different scales. Which lab and which test did you use to obtain that figure of 63? What is the normal range? Going by total testosterone alone, TRT would be inadvisable. Also, if...

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.
