    When does estrogen become a concern?

    Sorry I skipped over that part when reading.

    When does estrogen become a concern?

    What does your bloodwork look like? Total T, e2, shbg, etc?

    When does estrogen become a concern?

    The Dht to e2 ratio probably matters even more for this than total T to e2 I would guess.

    20mg Test subq daily, total test > 30 ng/ml Magic happens :-)

    Make sure you get the LC/ms-ms test for testosterone. Nandrolone can show up as testosterone on the standard assays.

    Can a keto diet cause elevated hematocrit & hemoglobin?

    I'm on a red meat based ketogenic diet for several years now and my hematocrit and hemoglobin are exactly the same as before. Are you staying hydrated before your blood tests?

    Once a week injections

    I would imagine that once a week is probably better for a lot of guys than no TRT at all, and that these clinics can make a lot of money by bringing guys in for a weekly shot of testosterone and charging them for it?

    Deca (nandrolone) added to trt and wow!!

    Hey I'm trying to learn and follow along here: I always read that the it varied person to person, not just their shbg number, but also how strong the shbg was at binding. Is this research showing that 98 percent of Caucasian males have shbg that's basically the same as far as it's ability to...

    Why do we aim for such high troughs?

    I know it's different person to person but I was just curious. Sorry to hear about the leukemia. I hope you're fighting hard through it.

    Why do we aim for such high troughs?

    Thx I appreciate the level of detail in this post. What dose were you running for QD and QOD? Also, I have mid-range SHBG (35) but my albumin seems to run high (4.9 on my last test). From my reading I see that albumin is weak and doesn't make as big of a difference as SHBG?

    Why do we aim for such high troughs?

    Oh ok I got it, I misunderstood what you meant in your last post. The analogy makes a lot of sense. I like the idea of daily injections too, although less frequent is definitely easier. I was just wondering if it would be overkill compared to every 3.5 days if low shbg wasn't an issue.

    Why do we aim for such high troughs?

    It seems like cypionate pharmacokinetics would show that it lasts for several days though https://anabolic.org/wp-content/uploads/2015/04/testcyp.jpg

    Daily Injections Help

    I fell into this trap recently. I was doing just decently on a protocol and decided to change it. Worked for 2 weeks, and then as soon as it stopped feeling good I changed immediately and spiraled into changing my protocol every 2 or 3 weeks and nothing ever worked. I'm just deciding on a...

    Why do we aim for such high troughs?

    How do you feel though? Have you ever seen the Tru T Calculator? It's supposed to be much more accurate.

    Why do we aim for such high troughs?

    You are low shbg though I am guessing? I would think for guys with average shbg a level somewhat stable from 700-100 should be fine?

    Why do we aim for such high troughs?

    I agree with the logic of course. It can explain why some guys have e2 numbers that look fine at trough but still might experience symptoms.

    Why do we aim for such high troughs?

    My understanding of testosterone levels from cypionate has me wondering, why do we aim for such high troughs? If we are injecting every 3.5 days and testing trough at 700, our peaks are likely 1000+ which is borderline supraphysiological. Wouldn't aiming for 1000 or more on a trough be...

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.
