    About to Start a New Protocol

    Short term gain vs long term pain. C'mon Systemlord, there are limitations to every statement; for example, can a chronic pain sufferer be allowed to dose until "they feel their best"? If so, you know what happens . . . You need both forms of feedback; you need to listen to what your body...

    About to Start a New Protocol

    Exactly. And in layman's terms . . . because many men, especially older men, have compromised "this and that", juicing yourself with excess hormones will/can backfire in ways that you're guaranteed not to like. At my highest 84mg/wk dose, measured in the trough, my TT was 29.5 (8.4-28.8) and...

    About to Start a New Protocol

    I'd go back to the endo. I'm 69 and scored high TT and FT (in excess of the normal range) on 84 mg T enanthate. I then had a TIA, which many suggest could be related to excess T from TRT for older men. Realizing that I was playing with fire, I've since reduced my dose, which still leaves me...

    Starting TRT Soon

    I think the A-Fib has gone away since reducing the dose, but as always things are hard to say. After the TIA, I was required to wear a holter heart monitor 24 hours a day for two weeks (what a hassle . . .). During that time, they later told me that I had 2 episodes of A-Fib; one lasted 30...

    Starting TRT Soon

    I'm 69 and started out very conservatively at 70mg/wk. I had OK results, but impatience drove me to boost myself to 84mg/wk (where . . . "yes, I felt better"). After 3 months of that, my TT was 29.5 nmol/L (8.4 to 28.8) and my FT was 744 pmol/L (179-475) - both much too high. Clearly I'm a...

    Good first Trimix experience, but questions remain . . .

    I thought I'd update my story thus far. After trying the 16 units and realizing that the effect was much like what I was getting when I took only 8 units (except for the extended duration), I started to feel my success with the Trimix would not be dose dependent. It did feel very much like a...

    T.Cyp 100 mg/week - Night sweats, anxiety

    You shouldn't immediately make the assumption that whatever ails you is tied to this point where you're getting your T dialed in. You may have something entirely different going on . . . because of that you should get a complete workup with your doctor. Night sweats can be caused by many...

    Joint Pain and Supplements

    I had a problem with sore joints when I first started TRT; I started in too quickly, and then you get sore. I learned a few things though, aside from taking your time getting into it and then a long, slow warm up. I discovered that the solution to my shoulder problems and all the popping and...

    Good first Trimix experience, but questions remain . . .

    Update, tried 13 units a couple of days ago; same 8.5 max erection as when I tried 11 previously. Went away in 3 hours. But disturbingly, I note that unless the physical stimulation is constant, it starts to lose pressure and soften to a 7.5 or 7. I had the same problem with Viagra. Could...

    Good first Trimix experience, but questions remain . . .

    Tried 11 units today; it was pretty good with a 8.5/10 erection, I think I'm finally getting close to my ideal dose. It also stuck around for about 3 hours afterwards in the form of a softer but not yet bendable erection. Next time I'll try 13 units; it could be that I settle eventually around...

    Good first Trimix experience, but questions remain . . .

    Hey Mooseman, your post above and from last Thursday have been on my mind since I read them; it's early still, but thus far I'm thinking that's what will happen to me. It's been about the same as my failing Viagra, and you hit the nail on the head when you described losing erections between...

    Good first Trimix experience, but questions remain . . .

    OK, fourth time, went back to the 5/16" 30g needle with 8 units; injected pretty well. Disappointingly, the erection was only marginally better than the first time when I took only 3.5 units. It was maybe a max 7.5/10; without massage it quickly goes back to a 6.5. So I know one thing for...

    Good first Trimix experience, but questions remain . . .

    Ok, tried Trimix for the third time, this time with 8 units. The first two times were with the shorter 5/16" 30g needle, and they only worked when I pushed the needle in extra hard, so I thought I'd try a longer 1/2" 29g needle. The 29g is OK, no extra pain, but . . . it didn't work. I put the...

    Good first Trimix experience, but questions remain . . .

    Even though I'm very early in the Trimix game, I'm kind of fearful that it'll give me an "adequate" erection, but also won't knock my socks off. I probably feel like that because I've read about those lucky users who've had super rigid erections, and frankly I'd like to surprise my wife with...

    Good first Trimix experience, but questions remain . . .

    Really I'm hating all this talk about broken needles, especially in my dick. You would think that if it did break you could retrieve it with some tweezers (I'll now keep tweezers on hand when I inject), but you'd have to have the presence of mind to keep it together . . . and if it migrates...

    Good first Trimix experience, but questions remain . . .

    Hey Mooseman, thanks for the commentary. Both my first two Trimix's thus far were with the 30g 5/16" needle. I tried bending the needle today on a scrap piece of wood and was shocked how easily it bent. Then I bent back and forth a few times and it snapped off. Really I haven't read of...

    Good first Trimix experience, but questions remain . . .

    Well I did round two with Trimix with a very conservative 5 unit dose; it wasn't much different at all from the 3.5 unit dose that I did a couple of days ago, leaving me with a 7/10 erection that lasted about 40 minutes. That leads me to believe that I'll ultimately need 10-12 units or more to...

    Good first Trimix experience, but questions remain . . .

    Thanks Nelson. I'm surprised you use a 27g needle to inject Trimix: I use a 27g to inject my T, which is much thicker than the Trimix. Isn't the idea to use the smallest gauge possible when injecting the penis? Do you notice a greater pain level with the wider needle? I don't think I'm a...

    Good first Trimix experience, but questions remain . . .

    Hey guys, I'm 69 and on TE for a year. Been on Viagra about 10 years, but it's really not cutting it anymore. Just had my first 25/20/1 Trimix experience, thank you Nelson Vergel for your excellent instruction. I've always had a good response to small doses of any medication (T included); I...

    Testicle Stretching

    Can you survive without T though, if your own production has shut down and you can't access exogenous T? And if you can survive, what kind of "man" would you be? I know that most people reading this would suggest that failing to have an adequate T supply available for purchase is entertaining...

    Testicle Stretching

    Your reasoning makes sense. I find now that I'm near the 1 year anniversary of starting T, that I'm thinking of many factors. I like the T; it's much improved my body profile. I'm 6'3 and before T weighed 245-250 and now weigh a more muscular 215. I like biking, and it seems that I can ride...

    Testicle Stretching

    Well that sounds terrible; thankfully I don't have that problem. I've been on TE (and nothing else) about a year and the two physical things I note about my genitalia is that the testicles are marginally smaller and that they are pulled tighter to my body. I'm not crazy about either aspect...

    Testicle Stretching

    Phil, I don't mean to derail the original topic of this thread, my apologies. However I'm intrigued by your and Vacationman's comments on HCG. Being 69 years old, I don't care about fertility; if that's the case then can you tell me if there's any other benefits to HCG besides preventing the...

    Testicle Stretching

    Hmmm, I never considered the option of taking HCG; in fact it was never offered to me by my endocrinologist. I've heard that HCG can present it's own set of problems, so I never pursued it . . . but maybe I should? I'm quite happy with my TE and how it's working; maybe introducing HCG would...

    Testicle Stretching

    I like to keep things simple, so I don't take HCG, only the T. It's been about a year now and I've had about 20% testicle shrinkage - they're fine, you don't really notice it. But the tighter scrotum bugs me a bit; your point about the body treating them differently because they've shut down...

    Testicle Stretching

    While I would never have mentioned it otherwise, the nature of this email addresses one negative aspect of my T therapy that I've noticed. Having been on TE for a year, most results are positive, but one thing that I don't like is that my scrotum is pulled much tighter to my body (like when I...

    Doc prescribed TRT - drop HCG?

    I've been on TE for about a year; I wanted to keep things simple so I didn't take anything else. I don't care about fertility either, I'm 69 now. Penis doesn't shrink. Testicles are smaller, but not by a big amount, maybe 20% smaller. Maybe they'll shrink further, but right now I'm OK with...

    Trimix while on blood thinners like Apixaban?

    Nelson, thanks for the responses above. When you say I could be prone to bruising, are you referring to discolorization the size of a nickel or dime . . . or the kind of darkening effect that I saw on images when I input "penile hematoma" - which is truly shocking. Some of the pics are of...

    Trimix while on blood thinners like Apixaban?

    Hey guys - I'm 69 and have been on TE for about a year, love it. I had a TIA in December and was recently put on a blood thinner / anti-coagulant being 5 mg Apixaban (Eliquis) twice a day, permanently. I saw a urologist a few days ago about beginning Trimix. There's a $300 fee payable before...

    Advice About Hematocrit and TRT Dose

    Some men do well on lower doses of T; I'm one of them. I'm 69; have been on T about a year and I've experimented with dosages of 60mg/wk to 84mg/wk. I inject every four days and currently am taking 9.5 mg/day or 66.5 mg/wk. At the higher dose, my hematocrit also reached 52 . . . and I had a...

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.
