    Bloodwork results and opinions/advice

    Free testosterone is what's relevant here, not total. His is considered to be healthy and normal for an adult male, and further indicates that the chance of being overtly hypogonadal is quite small. You can argue that statistically it's likely to be somewhat below the average for his age...

    Which clinics prescribe propionate?

    @madman has some excellent posts explaining the mechanics of honeymoon periods. When you read men's accounts of these periods you might think TRT is a panacea. The problem is that often the post-honeymoon let-downs are reported in different threads, so you might miss the reality of TRT. The...

    Bloodwork results and opinions/advice

    Me: Grok, rewrite this sentence so that even a child can understand it: "Without an age-stratified reference range there's no evidence that your testosterone is particularly low for your age." Grok: We don't have a special chart for this test that shows the normal amounts of testosterone for...

    Which clinics prescribe propionate?

    It's challenging to give advice while the story is shifting. The return of morning erections is significant and suggests you should continue with the oral testosterone. You're unlikely to do much better with propionate, although you might enjoy a short-lived honeymoon period. With respect to...

    Which clinics prescribe propionate?

    The lab work you posted earlier and the lack of improvements from oral testosterone are suggesting that low testosterone is not your problem. It's not impossible that your elevated E2/T ratio is contributing to issues. If you can lose more weight then that is the preferred way to reduce the...

    Bloodwork results and opinions/advice

    Unfortunately you are getting some dubious advice from Vince. Without an age-stratified reference range there's no evidence that your testosterone is particularly low for your age. TRT clinics have an inherent conflict of interest, so just because they might prescribe TRT doesn't mean it's...

    Any other Prop blend options?

    Solution: A quick-and-dirty auto-loader. https://www.excelmale.com/threads/need-help-with-t-cypionate-vials-single-vs-multiple-what-do-you-guys-use.27794/post-255297 Yes. I had originally found that getting roughly the same amount of testosterone from each ester led to a diurnal variation in...

    High hematocrit

    Not sure what you're looking for. Your doctor had previously prescribed the obvious solution: lowering your dose to a more physiological level. It sounds like you felt some withdrawal symptoms and gave up too quickly. Apparently you also donate blood without telling your doctor. I think you are...

    Diminished sexual function after starting TRT

    You're being too charitable. His statement is just ignorance delivered with an air of authority. In the context of the overall hormonal disruption caused by starting TRT, the relatively low dose of hCG is a ways down the list of potential primary causes of sexual dysfunction. @radman: The main...

    Any other Prop blend options?

    Unfortunately the DIY approach is likely the only option for getting a propionate blend with a higher fraction of propionate. Discussed in detail here: https://www.excelmale.com/threads/tips-on-how-to-blend-propionate-with-enanthate-or-cypionate.23485/ Obtaining pharma-grade propionate may be...

    Primary Hypogonadism: Doctor wants to put me on 25mg of Testosterone enanthate per week

    Though I can't be definitive, I suspect low and steady exogenous testosterone may provide better results in these cases. The idea is to provide a fixed base level of testosterone and then let the HPTA do the fine-tuning. Faster-acting testosterone such as oral or nasal products produce high...

    Primary Hypogonadism: Doctor wants to put me on 25mg of Testosterone enanthate per week

    There were two guys with primary hypogonadism on the old PeakTestosterone forum using this kind of treatment. I thought I might have discussed it with a different guy here as well. Consider the relative rarity of guys with primary hypogonadism—I recall Dr. Saya commenting on how infrequent these...

    Primary Hypogonadism: Doctor wants to put me on 25mg of Testosterone enanthate per week

    I was defining suppression as being below normal baseline levels. It's just semantics. If you want to say that hyper LH/FSH levels are being suppressed back to normal that's fine. But while that's happening serum testosterone is rising to normal levels—before suppression of endogenous...

    Primary Hypogonadism: Doctor wants to put me on 25mg of Testosterone enanthate per week

    From the Grok AI: The premise—that low-dose exogenous testosterone, titrated gradually, can normalize serum testosterone levels in primary hypogonadism while reducing initially elevated LH and FSH back to normal ranges without full suppression—aligns with physiological reasoning rooted in the...

    Primary Hypogonadism: Doctor wants to put me on 25mg of Testosterone enanthate per week

    This study applied to men who had natural testosterone production completely suppressed by a GnRH agonist. It's an apples-to-oranges comparison. The OP's doctor has probably forgotten more about TRT than you'll ever know. You are thinking about secondary hypogonadism. With primary the...

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.
