    Sub-Q injections becoming more painful, why?

    Hi there, been injecting for about 5 weeks now, sub-q and abdominally with a 29g needle. At first, painless but injections this morning and Saturday were much more painful. I just found another injection site on my stomach which was much better after the initial painful prick. Is the pain due...

    Travelling while on TRT to Australia - any advice?

    I will have a doctor's prescription with me and would like to know whether I should take my gel, or test. cypionate and syringes. I really can't afford to have my gear confiscated and not be able to dose for 2 weeks while on holiday there.

    Muscle building and TRT / T levels

    Hi I have a very basic question: Assuming that through TRT I as a 46M gets my test levels to those of an 18 year old (something like Total T: 30 nmol/L and Free T 720 pmol/L), does this allow me to build muscle like an 18 year old could? Forget supraphysiological doses, I'm enquiring only for...

    Increased test. dose and crazy anxiety - beware!!

    Hi I read that increasing your dose of T too quickly acts on cortisol and epinephrine,which can cause panic and anxiety.

    Increased test. dose and crazy anxiety - beware!!

    Hi All, So firstly this is all on me as I messed with my weekly dosage and learnt a very, very hard lesson this past weekend. I doubled my dose from 100mg to 200 mg a week last week without increasing it slowly, as I've read that more androgens will hopefully lower my SHBG levels. From Thursday...

    First sub-q pin this morning - advice please

    I've been on gel for 7 months and progressed to subq this morning. Using Test-Enanthate and will pin EOD 0.25ml for a total of 1ml/200mg test per week. Yes 200mg is a lot to some but need to see if it will drive my SHBG down. So, using a 29g insulin needle, I battled to pull the esther into...

    Anavar or Proviron to lower SHBG

    Ok thanks, I'm taking 0.5mg Arimidex 3 x per week to prevent aromatisation and my E2 levels aren't too bad (57 pmo/L) so perhaps the red face or flushing is something else? Blood pressure?

    Anavar or Proviron to lower SHBG

    Thanks Vince. Yesterday and today I dosed 35mg of test (double my normal) and I can feel a big rush (I'm also red faced and feel hot) the idea was to dose 220mg a week. How much test is considered safe to increase to, in order to raise Total Test? To recap was on 16.2 mg ED, for 113mg a week...

    Anavar or Proviron to lower SHBG

    Hi there, since my SHBG is sitting at 58 nmol/L I am interested in lowering it and keeping my levels in check. I'm on Zinc, Vit D3, Boron and Magnesium and don't drink alcohol and it still keeps creeping upward. I'm considering a low dose (5mg ED) of Anavar which Dr Rand Mclain has used with...

    DMSO Protocol for Test Gel

    Sooo.....you suggest that I stay away from experimenting with Ostarine? I don't see it as a viable long term solution anyway, would be nervous of that.

    Seroquel / Dopaquel and T, SHBG levels

    Anyone know if Seroquel/Dopaquel (Quetiapine) affects total, free T and SHBG levels? I take half a 25mg pill as off label use for sleep about 3 times a week as needed. It works really well, but my SHBG level is 63 nmol/L and wondered if it spiked due to the Seroquel.

    DMSO Protocol for Test Gel

    When I started in Feb my blood work was really good a month later, but since then my SHBG levels have climbed and my free test levels have come down. I managed my E2 levels with Arimidex half a tab twice a week. I am looking to get more of the test gel into my blood and hopefully get my free...

    DMSO Protocol for Test Gel

    Hi, I have been experimenting with a daily moisturizer that has some SPF 15 in it. Can you apply the moisturizer like 20-30 mins after the test gel once its completely dry or do you have to wait the fully hour. Another member posed this question a while back but there wasn't a clear answer.

    DMSO Protocol for Test Gel

    Hi, I’m looking for advice on how to dose my test gel while using DMSO topically to increase absorption. I’m on a 1.62% gel that amounts to 16.1 mg a day or 113 mg of test a week. In theory if I use DMSO to help absorption I can cut down my daily dose of gel as I understand, as you apparently...

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.
