    HCG induced aromatase down regulation?

    It probably will not, there are not many of us weirdos around...on another note, injecting HCG and FSH with the same syringe to shoulders with 8mm slin pins causes absolutely no PIP, there is some evidence that HCG could have better bioavailability IM, i wonder why the trend to inject...

    HCG induced aromatase down regulation?

    After those results i started injecting shoulders twice weekly, i upped the t dose to 30mg, then 37.5mg for just a few times before running labs again, hcg and fsh was kept at 500+90, so the weekly total is twice that for t and gonadotropins. Labs are not through numbers this time as i felt like...

    HCG induced aromatase down regulation?

    Yeah so far i only found one case on reddit explaining a similar scenario, and i'm fully aware that most people will suspect this to be impossible since as you described, the problem is almost always the opposite, it seems something happens over time, HCG will not cause this low e2 state from...

    HCG induced aromatase down regulation?

    Just wanted to see if anyone has anything similar going on, this is the second time i have witnessed on my labwork this strange phenomenon of tanked estradiol on combined HCG and testosterone. Now, i'm not certain if last time i was also using test subq, FSH was not in the picture back then...

    FSH stimulates aromatization

    I did try 150iu of FSH and felt bad, at first i was also doing mon-wed-fri, 500+75, after a short trial total T was 15nmol/l or 430ng/dl, shbg being quite low free testosterone was decent but i lacked libido among other things, E2 was almost low which is funny. My current stance is that using...

    FSH stimulates aromatization

    Yes, this is very basic and easy to understand, it only takes around 1000iu of hcg per week to have physiological levels of ITT, i doubt e2 induced infertility will be a problem on FSH. I am currently taking 500iu of hcg and 90iu FSH every 3,5 days. I wish i could have sustained it longer...

    Sperm result after 3 months of HCG. What would you do?

    While recombinant FSH is not, at least in most parts of the world, if one can't afford a short run of it, i would question if having a baby is something one can afford. Also freezing sperm for 10 years will probably be more expensive. Not nearly all guys end up with good sperm on HCG only, and...

    Why Men’s Fertility Is Declining: The Truth About Testosterone

    But it lasts longer, peak testosterone is achieved around 72hrs and it takes almost twice that for hcg to clear.

    Sperm result after 3 months of HCG. What would you do?

    HMG does work, it's human derived menotropin that in addition to FSH contain also LH, but the half life for the LH component is very short so hcg should also be kept on board.

    Sperm result after 3 months of HCG. What would you do?

    To each his own, after years of trial and error and bloodwork, i have come to the conclusion that 2000iu daily keeps me around 85nmol/l during winter months when no uvb radiation is available. Larger doses have always caused issues like anxiety and nausea. I despise people who never do or...

    Morning erection won’t go down without help

    Do you mind sharing your exact protocol? Obviosly results may vary but it's always nice to know how someone gets results like this that many never do.

    Sperm result after 3 months of HCG. What would you do?

    2000iu D per day is usually sufficient, +1 on the FSH, trying to revive sperm on HCG only is kind of outdated anyway, you only need a little bit of hcg to have some intratesticular testosterone with the FSH.

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

    Hey i remember you legend, remind me if it was subq or IM? HCG was never in the picture if i remember correctly.

    HCG DOSE FREQUENCY FOR MEN - FERTILITY & TESTICULAR ATROPHY

    How about trying out a reduced dose of HCG, for example 500iu 3xwk, and dropping the AI, that e2 level is IMO low considering that your t-levels are so high, which leads me to believe a drop in hcg dose would still leave you with plenty of T, gonads definitely going strong with you. Maybe the AI...

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.
