    TRT Dose question

    Yeah anything above like 900ng it’s like I’ve been castrated.

    TRT Dose question

    Something else I have I had a case that is really perplexed to me and doctors over the years is, if my levels are any bit over 800 ng, I have absolutely zero libido. I feel like a neutered dog when my levels are high and have absolutely no desire whatsoever for sex. I went to Dr. John Crisler a...

    TRT Dose question

    It’s good to see others like us that are finding more is definitely not better. My current doctor now and several I’ve had in the past will give you most any dose to relieve your symptoms. When my levels get anywhere near or over 1000ng, I feel absolutely awful. They’re just as no other way to...

    TRT Dose question

    Definitely sticking to once weekly for now and no I’m not feeling bad the day after. I normally use a 25 gauge 1” needle for glutes or 25guage 5/8 for delta and rotate through the 4 sites. I feel like my levels climb a little faster in the delts. I also got an iron panel for the first time ever...

    TRT Dose question

    I was curious, so I went ahead and got labs on 50 mg per week. It has only been three weeks but I am feeling much better in all regards. I was surprised how high the levels still are and this is day seven in the morning of my shot before my shot. Definitely goes to show in someone like myself, a...

    TRT Dose question

    I decided to do 50mg this shot a few days ago and already feel much better. I think the statin decreased shbg causing my levels at 60mg to be higher. I hope it continues because until the statin, I felt fantastic for years on once weekly 60mg.

    TRT Dose question

    Yeah I was doing great until staring that statin and somehow it has raised my T levels verified with labs

    TRT Dose question

    I feel like the more frequent my injections in the past, the higher my levels climb.

    TRT Dose question

    I’ve been at 60mg per week for several years. All in all I do feel really well but still think it’s a bit too much and it has seemed to change since starting a low dose statin.

    TRT Dose question

    They were always normal but I’ll have to look back at some older labs to see exactly where they were.

    TRT Dose question

    Now that you mention low ferritin MCHC this last set of labs was at the bottom of the range which is related to iron. Could this be causing the fatigue?

    TRT Dose question

    Yeah for some reason I thought ferritin was only necessary if donating blood? I can definitely get it and see where it is. I’ve never had iron checked either just normally cbc and cmp.

    TRT Dose question

    I think even at 60 mg I’m still going too high for a few days or at least that’s the way it feels.

    TRT Dose question

    So in your best guess would it be prudent to try a lower dose weekly in one shot or spilt a lower dose?

    TRT Dose question

    The last shbg was 66nmol

    TRT Dose question

    These were in May of this year. I’ve never checked ferritin and these labs were after a couple weeks of 80mg per week. Everything would be a little lower in the ranges I told you earlier doing 60mg. 80mg made me feel worse.

    TRT Dose question

    Some of the literature states statins can lower SHBG but really doesn't elude to what extent.

    TRT Dose question

    So do you think it would be worthwhile lowering the total dose and splitting it or lowering the once weekly dose to 50mg and then get new labs? I would of course wait 6 weeks or so to see where things land and again the only thing that has changed in the last several years is the low dose statin.

    TRT Dose question

    That's sorta what I was thinking and maybe doing 40mg using 20mg Monday and Thursday. At one point I did 200mg every other week and still had t levels of nearly 900NG day 14 but felt like hell the first week,
  21. S

    TRT Dose question

    Far worse, especially fatigue but my levels were also very high. The only thing that's changed in the last several years since going to 60mg per week is, I started a Statin which is 5mg Crestor 4 days per week. I have read that it can affect SHBG but not sure if that's true or even if the amount...

    TRT Dose question

    Really my only reason for answering that way is, I have did labs over the years to the point of nauseam and they never change, ever. I don’t feel any different than when I started this lower dose several years ago and I’ve always had slight fatigue the day after my injection and I’ve always felt...

    TRT Dose question

    I have had it measured with LMSC assay in the past and at the current dose it was 18ng day Seven. I measured it several times using this method and it never changed so at this point I don’t see why it would have changed now. As I said for now I do feel well most of the time and libido is far...

    TRT Dose question

    For those that have known me over the years know that in the past, I definitely had my struggles with TRT and I’ve tried pretty much everything there is to try. I have now been on TRT the better part of 16 years and for the last several years, I’ve been using 60 mg once per week of testosterone...

    Why do some men need supraphysiological doses of testosterone to achieve normal levels

    Yes nothing but cypionate IM in delts with 5/8 25g syringes.

    Why do some men need supraphysiological doses of testosterone to achieve normal levels

    I am the complete other end of that Spectrum lol. I do once weekly shots of 60mg and on day seven I’m still at 750ng. I’ve been at this dose for years and feel great. I normally have SHBG levels in a 50–70 range. I don’t even measure free testosterone anymore or any other labs other than CBC and...

    Weekly shot lab timing

    She seems cool with everything but this one area which I think she’s just misinformed. I’m going to also take the cypionate literature that comes with the Pfizer vial to show her my next appointment.

    Weekly shot lab timing

    That’s sorta what I was thinking regarding her seeing higher levels midway between injections. I might just keep it as is and tell her they’re drawn on shot shot as I’ve done for years. Measuring midway for some folks could in fact leave them hypogonadal at day seven. Luckily my levels stay...

    Weekly shot lab timing

    I have a question for those that do weekly injections. I’ve been on weekly injections for many years. I’ve been on TRT for close to 16 years now I do just fine doing once weekly injections. I normally do between 60–80 mg per week of cypionate. Recently, my doctor retired and I had to get another...

    Is GnRH suppression hurting us?

    Once a week. I’ve tried splitting the dose but have to do 72-80mg to feel the same.
