    Advice on reducing test dosage

    Many thanks for your reply. Yeah sorry, I maybe didn't make it clear. The numbers on my blood test aren't my be-all, end-all. My main issue is that I almost constantly feel nervous and jittery. This is why I want to reduce my dosage. I'll try a 10% reduction in dosage and see how it feels...

    Advice on reducing test dosage

    Hi all, I'd like some advice on reducing my testosterone dosage. Please by all means, treat me like the idiot I am because I still have much to learn. Below is my latest blood test results (as of yesterday). Testosterone translates to 946ng/dl and E2 to 31.3 pg/ml. From what I understand...

    How to lower TRT weekly dosage safely?

    I'm curious about this too. I'd like to speak to my TRT provider about reducing my dose and I'd like as much information on the subject as possible.

    Is using a home blood glucose monitor that measures hematocrit a good or bad idea?

    So yesterday I donated blood and I asked my question about the "swinging" values of haematocrit and haemoglobin over the course of a day. Unfortunately the nurse who attended to me a little run off her feet and didn't answer my questions. However, I'm due to have bloods drawn by a phlebotomist...

    Is using a home blood glucose monitor that measures hematocrit a good or bad idea?

    I donate whole blood every 12 weeks. I'm in Scotland, UK and you can't donate any more often than that which is obviously fine. I've seen my own haematocrit being as high as 54 (about 18 months ago, which is before I started donating blood regularly) and as low as 47 (six months ago - I'm due...

    Is using a home blood glucose monitor that measures hematocrit a good or bad idea?

    No problem. I believe that haematocrit can still trend upwards or downwards in an overall sense which is why you should keep an eye on it but - and this is where my memory gets a little foggy - I think that the nurse I spoke to told me that it can swing as much as four or five points in the...

    Is using a home blood glucose monitor that measures hematocrit a good or bad idea?

    Haematocrit goes up and down considerably over the course of a day depending on how hydrated you are and how much you're moving around. Source: the nurse I spoke to during my last blood donation.

    Iibido without hcg

    I'm about a year into TRT under clinical supervision and - as yet - I haven't tried HCG. From the experience I've gathered so far, it seems that if I let my E2 get into the "higher" side then my libido gets really strong (as long as I don't let it got too high). That said, I only have a year's...

    Hi from Scotland

    Hi all, I'm xib. I'm a 48-year-old from Scotland, UK. I'm about a year into "proper" TRT after self-administering it since July 2018. For me, self-administration was OK, but there difference between that and doing it through a clinic is night and day in my limited experience. Right now, I'm at...

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.
