    Adding Anastrozole, how much should I lower dose?

    Excessively elevated DHT will have an anti-estrogen effect and lower your estrogen. There’s no way to predict where the AI will put your estrogen because we don’t know how sensitive you are to AI’s. That would be like trying to predict your tolerance to alcohol and how many beers would it take...

    Advice on next steps - mid-low free T

    I’ve been on both and my experience on oral testosterone is much better than any other formulation. Natesto benefits were very short-lived, a half an hour after each dose benefits waned. I stopped Jatenzo (competing brand to Kyzatrex) more than eight months ago and my HPTA fired back up after a...

    New blood work, 8 months on TRT (Estrogen blocker/donate blood)

    I would just change your dose. You need to focus more on the hemoglobin than the hematocrit. Estrogen tends to run higher on TRT.

    New blood work, 8 months on TRT (Estrogen blocker/donate blood)

    I would just lower your dose to 40 mg twice a week.

    2.5 weeks in, is ai necessary?

    This is turning out to be a high dose for you. Your hormone levels are not reaching a steady state until 42 days. The nipple sensitivity is expected and common and not necessarily related to estrogen but testosterone as well. The nipple sensitivity is caused by hormonal fluctuations. Starting...

    Male...gaining slight fat with cellulite in thighs all of a sudden even with normal lab results

    Almost no one gets enough vitamin D these days. Nothing helps you lose weight more than vitamin D. Vitamin D is also crucial for protein synthesis -> muscle building. Testosterone can’t build muscle without vitamin D. I noticed when I start taking more vitamin D my legs get harder and feel more...

    90 mg of Vitamin C causing erectile dysfunction, low libido, 24/7 painful penis sensitivity

    Well, it’s official, I’m vitamin C deficient and never felt better! If I even consume 10 mg of vitamin C I develop extreme nausea, dizziness, and lightheadedness. This lasts for 3/4 of the day. There must be something genetic going on. It’s been 5 1/2 months since I’ve stopped the vitamin C...

    Male...gaining slight fat with cellulite in thighs all of a sudden even with normal lab results

    Zinc is natural aromatase inhibitor and can decrease estrogen. I recall some members taking a lot of zinc and their estrogen was undetectable. DIM can shifts estrogen metabolism. You have the wrong ideas in your head about estrogen. By trying to balance estrogen better you have created an...

    Male...gaining slight fat with cellulite in thighs all of a sudden even with normal lab results

    High estrogen would decrease fat storage, low estrogen would increase fat storage and redistribute it to the thighs, hips, and chest. Maybe some DHEA would increase your estrogen a bit. Are you taking any medications or supplements?

    Looking for honest advice on hematocrit

    Donating blood only decreases hemoglobin and hematocrit for 2 to 3 weeks anyways and it’s right back to being elevated. There’s no mystery here. Get off this marry go round and change your dose.

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

    This was never meant to be a therapeutic dose, it was meant to prevent Ricketts. This is where the 2000 IU vitamin D per day comes from. 10,000 IU per day is a therapeutic dose. You can absorb 60,000 IU in just a couple of hours in the sunlight. You may need some vitamin K.

    9 years on Gel - Switch to Injection - Effect on HCT?

    With your HCT at 43% I don’t think you’re going to have a problems with HCT even on IM injections. Your SHBG will go down though. You could always go oral testosterone route, Jatenzo or Kyzatrex.

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

    Yes, vitamin D has a big impact on sperm parameters. Vitamin D deficient men have significantly lower total mobility, sperm quality, motility and progressive sperm motility. Vitamin D deficiency is associated with male infertility.

    Help with blood test results and erectile dysfunction

    Nope, high estrogen doesn’t lead to gyno, an imbalance of testosterone, estrogen, DHT and prolactin triggers gyno. Gyno is more common in men with low testosterone, not high testosterone. Study show that some men on TRT with estrogen below 42.5 have lower libido and ED because their...

    Test levels DROPPED after RAISING dose

    I mentioned the oral testosterone due to your comment about your red blood cell count. Oral testosterone doesn’t affect red blood cells to the same degree as injections. As far as maintaining between 800-900 total testosterone on injections, I wish you luck because total testosterone can change...

    Test levels DROPPED after RAISING dose

    You’re going to drive yourself crazy trying to target a specific lab value on injections. Get another hobby or switch to oral testosterone, which has extremely consistent absorption in the intestines.

    Testosterone dropped after a few months on the same dose

    You didn’t stay the same. Biology is constantly changing all the time. I did notice extremely consistent results on oral testosterone which shows intestinal absorption is more consistent overtime.

    Elevated hematocrit and hemoglobin, not all physicians have the same opinion ..........

    When I was on TRT, I hematocrit of 57%. My endocrinologist freaked out and ordered monthly phlebotomies. After a little more than a year, the hematologist at the infusion center who reviews everyone’s blood pressure readings, hemoglobin and hematocrit for the infusion center contacted my...

    testosterone super high on 200mg

    Biotin supplements will give erroneously high false hormone values in lab testing if not using the LS/MS and equilibrium dialysis method. As far as the elevated estrogen while on injectable testosterone, it’s quite common and is preferred, otherwise your testosterone to estrogen ratios will be...

    0.25mg oral Finasteride daily - risk of Post-Finasteride Syndrome?

    Some people don’t develop PFS until after they taper off the medicine. There’s a protocol for coming off, which is very high dose testosterone, injectables and creams to boost DHT very high.

    Low Test Levels & Lingering Symptoms at 24 After Teen Cycle —Clomid/Enclomiphene Worth Trying?

    High testosterone is relative to the person we are talking about, if you have a high sensitivity to the hormone, then your set-point to testosterone is different than that of someone else. Enter the realm of AR CAG repeats, lower the number the higher the sensitivity, the higher the number, the...

    So ignore what your body is telling you and base everything off a lab test? Let me put it another way, the goal of treatment is about making the lab number look good and instead of how you feel? Do you agree with this statement?
