    Levels TT / FT / SHBG before starting TRT

    So it sounds like you're in the U.K if you're going through Dr Stevens, and your readings were between 12 and 14 nmol/l? I'm also in the U.K, early 50's. For several years, my total testosterone was coming back at an average 8 nmol/l, so approx 230 ng/dl. I put myself on diy trt last year in...

    Hip Replacement Surgery Experiences

    Good luck! You're doing better than i am - i saw my (future) surgeon for the first time yesterday. I had seen the triage service in March who said i had to try and lose 9kg before my appointment with him, as my bmi was above the limit for surgery. Well i failed, but i did shift 6kg so thought he...

    I'm guessing the Peaktestosterone.com site's now gone for good?

    Depression while on TRT

    Why? I'm not taking it at the moment as i'm not currently working, but i did use it daily for a few years.

    These were my blood results from June this year:

    After 8 weeks on TRT - do these numbers look ok?

    I've just had a quick look at the syringes i've got, and actually it won't be any trouble measuring smaller amounts as each 0.1ml mark is further divided by 5 so each mark would be 6mg test, making it fairly easy to get 48 or 54mg per shot. Regarding my aromatase levels - i do indeed have a lot...

    After 8 weeks on TRT - do these numbers look ok?

    I'll be honest, i've noticed very little at all, no mentally or physically. This could be though because i'm currently spending my days sat at home doing very little (I lost my job the same day i decided to put myself on trt. Also, i'm waiting for the NHS to give me a double hip replacement...

    After 8 weeks on TRT - do these numbers look ok?

    Thanks, that's what i was thinking too. It's a bit tricky measuring as the concentration of test-e i have is 300 mg/ml (so it was easy measuring 60mg as it's 0.2 on the syringe). I think if i draw up a bit less than 0.2 then i'll be getting somewhere around 50mg per shot. I'll try that, thanks...

    After 8 weeks on TRT - do these numbers look ok?

    So after years of having private blood tests and trying to improve my levels naturally, i finally took the plunge just over 8 weeks ago and started on self prescribed replacement (i know, not the best way to go about things but i'm on it now). My last blood draw done back in June came back at...

    Hip Replacement Surgery Experiences

    Thanks Nelson, some great tips there i'll definitely look into the raised toilet seat (it's a struggle at the moment for me anyhow). I guess slow and steady would be the main takeaway from the experiences i've read here and elsewhere. I was reading about a guy earlier who had a replacement and...

    Hip Replacement Surgery Experiences

    Glad to hear you're doing well, it sounds like it's been a success for you so that's great. And yes, i'll definitely keep this thread updated with my treatment, whatever that ends up being. I was hoping there'd be a point in the future where i could get under a bar and do squats again. I'm not...

    Hip Replacement Surgery Experiences

    @Nelson Vergel and @Cataceous - just wondering how you two are both doing with your hip surgery recoveries now some time's passed. At the end of September i got results back from an xray on my hips. Wasn't good news, report said "advanced hip osteoarthritis bilaterally", and a few other terms...

    Hip Replacement Surgery Experiences

    Hi Cataceous, glad to hear your recovery's going well. I'm hoping that my x-ray won't show that i need surgery and that my symptoms come from my back instead, but the more i read about hip osteoarthritis the more it seems that's what i've got. And it's not that the surgery itself is worrying me...

    Hip Replacement Surgery Experiences

    How is your recovery going Cataceous? I've been pretty much out of action gym wise for the last 18 months due to lower back and hip pain. I'm in the UK, so going through the NHS for treatment (NHS is very, very slow, and it took a year to even get to see a physio). I'm waiting an the results...

    Testosterone Blood Test Results - Time of Day?

    Ok, well all i'll say is that finger prick tests are notoriously hit or miss. I'd get another venous test if i were you, i suspect your 2nd result was more accurate

    Testosterone Blood Test Results - Time of Day?

    Were either of these tests done via finger prick? By the way, even with your reading of just over 9 nmol/l, the nhs won't consider treatment

    Information about Proviron

    I'll have to do a bit more digging as it's been a while since i read the study that led me to the conclusion proviron affects the gonads. I also realise though that i could be wrong blaming it for my own drop in testosrerone - there is of course a chance that i just developed low testosterone...

    Information about Proviron

    Just quickly, because i'm at work - https://pubmed.ncbi.nlm.nih.gov/6431212/ It would seem that if you're starting off with a high testosterone level, it's not so problematic. But it reduced total testosterone in all subjects

    Information about Proviron

    Hi again. I was taking 25mg, monday to friday for probably 5 or 6 months before i started getting symptoms (dry joints). No steroids or trt, just low dose clomid therapy. I guess it could be coincidence, but at the time (end of 2017), i researched further into proviron and found a study that...

    Information about Proviron

    It sounds great when you read through that. Keep in mind though, that was Bayer's advice in 1979 - do they even make it any more? And why isn't it a commonly prescribed treatment now? I also felt great on it to start off with (ie, while my test levels were still ok). But within months, my LH was...

    Information about Proviron

    Proviron without trt would be a terrible idea. I did it, as i'd read it isn't supressive etc. I was taking 25mg most work days, as well as the low dose clomid i'd been on for seversl years. After a few months of having taken proviron, my joints started to hurt and i literally couldn't crouch...

    TRT Providers in UK

    Balance My Hormones have a terrible reputation in the UK. Apart from over charging, there's a long standing joke about them on UK forums that if a 12 year old girl walked into their premises to ask for directions, she'd walk out with a prescription for testosterone, hcg and arimidex.....

    Should I restart TRT? Labs Included

    Thinking about starting trt

    I bet the OP can't wait to start treatment now after wading through the last four pages!! (sarcasm). I'm not on trt, maybe should be - but from what i've read over the last ten years following this and other forums dedicated to trt, using the lowest effective dose always works out best for...

    Calling All Long-Term TRT Users! How is Your Libido and Sexual Function?

    What i'd be interested to know is, are the people having libido / erection problems on trt having them BECAUSE of going on trt, or did they have these problems before starting, and the trt just hasn't helped?

    Thinking about TRT

    Oh ok. Well i'm suprised at that as i thought test undecanoate was the longest acting (ie as in nebido). Maybe taken orally its effects are different then.

    Thinking about TRT

    Is it known why? I thought any exogenous testosterone would cause shutdown, especially long ester ones like jatenzo uses

    Thinking about TRT

    I wouldn't touch d-aspartic acid unless you want even lower testosterone. I believed all the hype when it first came out, and after having had a low test result myself thought i'd try it. Well, two weeks later the doc tested me again. My total testosterone had dropped from 12 nmol/l down to 9...

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.
