    Retatrutide - A Game Changer in Obesity Pharmacotherapy

    I'm sort of a highly sensitive person. So, if someone is in the same boat, better start with 0.5mg.

    GHK-cu and DHT

    I have underlying MDD and maybe that's why GHK-cu has that effect for me. Impact on neurotransmitter regulation and anti-inflammatory effect in the brain are possible explanations.

    Retatrutide - A Game Changer in Obesity Pharmacotherapy

    Retatrutide has a halflife of 5 days. Do you notice it? Would twice weekly be better?

    Tren Improves Cardiometabolic Risk Factors and Myocardial Tolerance to Ischemia-Reperfusion in Male Rats With Testosterone-Deficient Metabolic S

    I have been testing 20mg TrenE per week, while reducing T dose. Impacted sleep negatively but feeling overall more awake. Going to test 10mg per week while having reduced TU from 125mg to 75mg. In think it would be best to have tren cream for circadian rhythm. Is this possible similar to t cream?

    GHK-cu and DHT

    Did you notice any mental effects from GHK-cu? I started yesterday (2mg) and it gives me a mental boost, like a long lasting double espresso. Maybe this is an initial effect? Histamine release?

    My Father is 70 years old and we just got his labs done. I'd like your advice

    That's the T reference for <39 yrs. How is the blood pressure. Would fix low sodium levels. Check B12 and folate. Metformin is a high dose and maybe too high. Is it once per day or split?

    Maybe the maintain weight estimate is wrong ;) Burning fat, gaining muscles, holding more water?

    Test cyp 6 months - still can't dial in

    Maybe best to stop the trt experiment. Imho the bit more T YOU get from trt is unlikely to make a significant difference in muscle gain. Brain fog can have many causes...

    Test cyp 6 months - still can't dial in

    Before TRT no ED and normal libido? Brain fog gone with Estradiol and Prolactin now at higher end? With your high FT you could further reduce the dose, and split your dose to 3x/week.

    Feminism and male testosterone

    TRT vs Clomiphene: Effect on IGF-1

    What Nelson posted: " Magnitude matters clinically Even the largest falls with SERMs kept IGF-1 within the adult reference range in most subjects, so frank GH-deficiency symptoms were not seen. Testosterone-related rises were modest; reaching the upper-normal IGF-1 range is uncommon at...

    Estradiol 230 pmol/L too high?

    Wonder what her plan is. TT of 40? You could ask her! Your FT is already very high. Imo you should rather reduce and split the dose.

    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    AI: 1. The "Muscle Meat Only" Carnivore: This is the biggest risk. Someone who eats only steak and ground beef with no sources of dietary calcium (no bones, no dairy) is at high risk for a negative calcium balance. The body will maintain blood calcium by increasing PTH, which will pull calcium...

    What's the u-shape for estrogen?

    We get three hormones with TRT and strangely their ratios are not the same with topical, oral, injection and with different esters or IM, SC.

    Please tell me how vitamin D supplementation has caused calcium deficiency, let's discuss.

    What my AI thinks The core of your problem almost certainly lies in the interplay between Vitamin D, Magnesium, and Parathyroid Hormone. · Most Likely Scenario (90% Confidence): You have an underlying magnesium deficiency. Supplementing Vitamin D exacerbates this deficiency, leading to impaired...

    Need honest advice: Do I really need TRT? Low-normal T, low libido for years, anxiety/OCD background, little muscle growth

    Regarding your concerns about fertility, you could search the forum for oral testosterone. I have no experience with it but that's what I would use (if I had access to it) to start or try TRT.

    Need honest advice: Do I really need TRT? Low-normal T, low libido for years, anxiety/OCD background, little muscle growth

    I asked my AI, it suggested you try TRT. Imo, it sounds multifactorial. It's difficult to give any advice. Do you have a problematic porn consumption?

    Lowering trt dose/ increasing frequency of injections question

    To me it makes no sense. Maybe some looking only at the trough level and chase a magic number.

    Lowering trt dose/ increasing frequency of injections question

    If you keep the weekly T dose constant and increase the injection frequency, it will flatten the curve, i.e. it will reduce the peak and increase the trough T levels.

    Tren Improves Cardiometabolic Risk Factors and Myocardial Tolerance to Ischemia-Reperfusion in Male Rats With Testosterone-Deficient Metabolic S

    That's my experience (Proviron, Anavar) but I felt like I had to state that. Nandrolone was terrible for me, however, most guys encounter only benefits.

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.
