    PT-141 Appears to work great only when sleeping?!

    A ferritin blood test shows ferritin levels. It’s well known that hCG can negatively affect libido.

    Excited to Join the Community!

    Welcome to ExcelMale. Some men are able to boost energy, physical and mental performance without the need for TRT. Cutting out the standard western diet (ultra processed foods) is a good place to start!

    Open vial degraded after 6 months?

    So changing SHBG levels and therefore a decrease in TT isn’t a biological change?

    PT-141 Appears to work great only when sleeping?!

    Testosterone can increase norepinephrine released from kidneys. So if you’re overdosed on TRT/hCG or you choose a half-life where hormones are consistently elevated, having less fluctuations, are sensitive to hormones in general, this can have an effect of overstimulation and therefore affect...

    Open vial degraded after 6 months?

    Your metabolism changes, day to day, month to month. Days are shorter in the Fall and Winter months. Your thyroid hormones are slightly higher in the winter months to regulate body temp. Your body is always trying to regulate itself. You should also note that the FDA allows deviation of...

    PT-141 Appears to work great only when sleeping?!

    HCG can cause sexual issues and can create an imbalance of many different hormones.

    The factor you never considered, your biology changed and so did your response to TRT.

    PT-141 Appears to work great only when sleeping?!

    Maybe there is a hormone imbalance during waking hours that does exists when sleeping.

    New Member -- Will Take All the Advice I Can Get; Initial Questions re Dose

    Theses protocols are ancient and stupid. These protocols see higher rates of erythrocytosis and don't maintain consistent hormones throughout the two week injection interval (works great for a smaller minority of men) and any doctor still prescribing these protocols is out to lunch! The...

    New Member -- Will Take All the Advice I Can Get; Initial Questions re Dose

    There's always oral TRT, Jatenzo and Kyzatrex gel capsules taken twice daily. The oral TRT route makes dialing in less about finding the optimal injection frequency and solely about getting the dosage right. Steady states in 7 days, compared to 4-6 weeks as with injections, makes dialing in...

    New Member: Worse Off than ever after years of TRT, HCG now not working, debilitating insomnia - Please Help !

    You need a reality check! There are no natural men walking around with a TT at 1300, in the absence of abnormally high SHBG, with estrogen <29! The estrogen ranges, which vary greatly between lab companies, are derived from men with TT below 500 and not men on TRT with optimized T.

    This may help explain some things, alcohol can increase estrogen. Estrogen helps with sleep. Some men have bottomed out estrogen on TRT and need hCG together with TRT.

    New Member: Worse Off than ever after years of TRT, HCG now not working, debilitating insomnia - Please Help !

    The cream is maxed out, you reached steady states in 1 week on the cream. When you first started the cream, your T was higher than it is now because of the doubling or stacking of the cypionate. When I first started Jatenzo, I had only just stopped the cypionate, I was stacking the two and T...

    That's not a good sign. You should already be seeing benefits. Your T levels must be declining. You should consider oral T, Jatenzo, Kyzatrex.

    TRT Numbers

    You did it wrong, no wonder your results are low. Back to square one, retest between 4-6 hours after application. Your TT and FT levels will rise within 2 hours after application and decline quickly. I was on oral T and half-life is identical to topical T. I would peak at 1052 ng/dL 2 hours...

    TRT Numbers

    TRT isn't working if you tested between 4-6 hours after dosing. TRT will be working when your TT and FT are near the top end or above the ranges. It may be time for injections injected weekly or twice weekly or oral T Jatenzo or Kyzatrex. If your urologist suggests injections every 2 weeks...

    Pre TRT bloodwork results

    It can vary, depending on your needs. Once you're dialed in on therapy, costs will drop. It's been awhile since I used a private clinic or had the need for one. I've had more problems than anyone here. I fixed my issues on the carnivore diet. Oral T, Jatenzo, Kyzatrex will make dialing in...

    Pre TRT bloodwork results

    Your doctor not wanting to talk about your testosterone panel, huge red flag! Your doctor is using the Direct FT method, often inaccurate and overestimating FT results, the equilibrium dialysis method being the most accurate method or even the calculated method. If your doctor had tested SHBG...

    Great free t lousy total t

    TRT will suppress the SHBG further. Androgens suppress SHBG. Low thyroid hormone (fT3, fT4 & high TSH) would cause low SHBG. Type 2 diabetes would also cause low SHBG. Not so fast, what method was used to measure the FT?

    Updated Clomid with labs

    I have a saying, you're the architect of your own destruction. Zinc is a natural inhibitor of aromatase. As far as the zinc dose not being enough to lower estrogen, depends on your individual biology. You have men out there that can take a 1-2 mg of aromatase inhibitors and it barely moves the...

    Kyzatrex - sudden emptiness feeling in head

    I don't see why you can't do two different doses morning and night. 400 mg morning, 200 mg nightly.

    T Levels and high Estradiol

    I was on it. I went off because I was having issues I later found out was caused by something else. My experience was a lot more positive than injections, creams and gels. I tried every possible injection protocol, daily, every 2 days, every 2.5 days, every 3 days, twice weekly, weekly, nothing...

    T Levels and high Estradiol

    On oral T, Kyzatrex and Jatenzo it's less about trying to aim for a particular hormone levels and maintaining it and more about getting the dosage right since hormones fluctuate hour to hour. An TT @886 won't be an issue on oral T because 2 hours later your TT is somewhere around @786 and 2...

    Libido - 1 huge leap forward, 5 steps back.

    Steady hormones isn't always optimal for libido. Steady hormones can lead to overstimulation for some is enough to mess with erectile strength and or libido. Oral testosterone, Kyzatrex or Jatenzo anyone?

    My HPTA recovery log: I have reversed my type 2 diabetes (SHBG 31/glucose 80) and may have never had hypogonadism!!

    Since stopping the vitamin C and D, no vitamin C in my diet, and consuming foods with vitamin D (eggs), today at the gym my strength is approaching near TRT levels. My energy levels are going up, sleep is great and I feel good mentally and at times I feel out of this world unlike I've ever felt...

    Should I continue trt or not?

    I meant doctors recommended restricting red meat to twice weekly, which is insane and flat out wrong! I should have been more clear on my statement. Medical knowledge is no longer the monopoly of physicians.

    T Levels and high Estradiol

    When in relation to your injections were labs drawn? I think it's obvious you're overmedicated. As far as dosage reductions, .1cc reduction in dosing isn't going to move the needle very far. I would start with .6cc reduction.

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.
