    Instant Blood Pressure Spike on Starting TRT

    Testosterone utilizes iron more to create more hemoglobin, hematocrit and RBC's. Check ferritin and iron saturation. How long did it take for these symptoms to appear after your injection? I wouldn't expect answers as to why you're experiencing these symptoms from your endo as they receive no...

    New Zealand does not let me give blood to decrease high hematocrit on TRT

    There's no possible way anyone could answer your question with any degree of certainty.

    Why do most say other hormones deplete while on TRT?

    Some men see an increase in other hormones, such as IGF-1 on TRT. As for a reductions of other hormones mentioned, this is less likely in the short term. Nelsen after decades on TRT loss the perceived benefits of TRT and years earlier had tried hCG and had a negative response, years later...

    10 Years on TRT and Only Recent Libido Issues

    Throw iron deficiency in there too. I confirmed iron deficiency from using Bisoprolol, a beta-blocker. My ferritin was seen reducing 14 points every ten days. The beta-blocker without a doubt caused stomach cramping which I believe caused malabsorption. After I stopped the beta-blocker 4 months...

    Warning for Men on TRT: Low Ferritin is Bad

    AI's can't affect E2 made inside the testicles as it can only block aromatase. some men have found that ever increasing doses of AI's have zero effect on E2 levels beyond a certain point. Also, lower ferritin on TRT/hCG isn't always a bad thing. The body will try to regulate the H&H be reducing...

    You’re not going to stay young forever and so bodily functions will not remain the same as your age.

    10 Years on TRT and Only Recent Libido Issues

    Your E2 is low in relation to your testosterone. I wouldn’t expect your endo to be very helpful. You need to get that estrogen level up.

    Elevated PSA

    Whatever you do don't get a prostate biopsy! This can cause any contained cancer to spread that would have otherwise remained dormant.

    Hesitating on TRT, Does Anyone Have Regrets?

    Something tells me you don't speak from experience, rather it seems like you've created a theory. I never had problems drawing cypionate using 32 gauge insulin syringes.

    Doctors in San Diego

    Feeling normal would mean you have no need for drugs, and surgeries. The american medical system wants you sick and know nothing of general health or what's healthy. Most mainstream medical doctors focus on disease management, and do not focus on healing the patient.

    I need some serious help with ED

    The people that make statements such as these are addicted to carbs and don't want to give up old ways. That dopamine rush, gotta have it! The body makes its own carbs even if you don't consume them. A weak study doesn't mean the study is wrong. It's well known that the carnivore diet can...

    I need some serious help with ED

    This is bad news for doctors, hospitals, and big Pharma. Your doctor can get in trouble if he/she were to recommend the carnivore diet. It’s not supported by the various agencies that write the guidelines for nutrition. Cheerios is highly processed food and cereals are in general very bad for...

    Chronically low ferratin levels

    Shorter half-life formulations of testosterone therapy do not affect red blood cells nearly as much as injections. Oral testosterone Jatenzo and Kyzatrex are options.

    Fellas and Ladies I need some advice

    Putting this woman on a pedestal is a countdown to the end of the relationship! Hypergamy needs to be satisfied for a woman to "feel" attracted to you. Once the attraction is lost, respect is gone and women start to become more distant. She will check out emotionally first, and you'll notice...

    Are you aware of the recent Harvard study on the carnivore diet? A 95% improvement is all diseases/overall health. This pretty much shows you the cause of most diseases. It's the diet.

    You can put your type 2 diabetes in remission. Carnivore diet will put you in ketosis and normalized your glucose. I'll bet your ED goes away too.

    What would you do? HCT vs. BP

    Neither, I would find another solution such as a shorter half-life injectable, perhaps enanthate if he hasn’t tried it already. Bodybuilders have reported for years that they experienced less bloating and water retention on enanthate versus cypionate. The difference in the way that I felt...

    Anxiety Issues after TRT discontinuation

    I don’t understand why you think a forum guru member is going to have more clinical and medical experience than Dr. Rob. From reading your post it doesn’t seem like you gave him a chance to solve your issues which doesn’t happen after only one visit. Did Dr. Rob do any more extensive lab...

    So your on an endocrine disruptor, very risky, especially considering we know what will happen long term. The average person only concerns themselves with short term results, having no foresight whatsoever. Avodart decreases DHT which contributes to hair loss and testosterone converts to DHT...

    Starting TRT Soon

    It would seem like whoever is prescribing your medicines is confusing the bodybuilding world with testosterone replacement therapy. Keep the Anastrozole only if you want to experience what low or crashed estrogen feels like and or osteoporosis. The Honda salesman told me I needed an extended...

    Supraphysiologic testosterone (350 mg weekly)

    The body when deficient will create more dopamine/testosterone receptors and when dopamine/testosterone is restored to normal, the body will down regulate because the body was never meant to operate in this fashion. You have body builders that are forced to return to normal hormone levels...

    Anxiety from Kyzatrex?

    474 mg twice daily Jatenzo got my midpoint T levels to 1052 ng/dL which would have my peak double. I was fu***** strong! 237 mg twice daily got me a midpoint Total T of 500. I’m natural now and have a Total T of 400-500 morning reading and Free T on the bottom and no symptoms of low testosterone.

    Supraphysiologic testosterone (350 mg weekly)

    These symptoms could be caused by a simple vitamin or mineral deficiency. Low vitamin D can cause all of these symptoms. I went on TRT for 8 to 9 years and had inconsistent results. Libido and erectile strength only improve temporarily. Found out I had low vitamin D and raising my levels fixed...

    Supraphysiologic testosterone (350 mg weekly)

    It’s going to take a bit longer for your body to adapt to the new hormone levels and to reach a steady states which is determined by the half life of the ester. This happened most likely because you were overmedicated.

    What would you do? HCT vs. BP

    I think your problem is the steady hormones isn’t agreeing with you and is causing less than optimal results. You need to look for a solution where you can have your cake and eat it too. Have you tried oral testosterone, Jatenzo/Kyzatrex? This way you can have high testosterone to get optimal...
