    New Member -- Will Take All the Advice I Can Get; Initial Questions re Dose

    Just in case this thread is helpful to others, a quick follow up. I underdosed a bit before my test, waited an extra day, and tested at the trough and came in a little over 600, which made my doctor happy. Low E2. So that buys me several months of insurance paid T before he makes me test...

    So far so good on 40mg 2x/week. I decided to test after a couple of weeks just to see what was happening. Morning of my shot (before the shot) I was at 745 TT and 26.8 E2, which I figure is pretty good. I feel fine. Had some fatigue when I first made the switch but things seem to be ok at...

    Thanks. I tested SHBG and it was pretty good.

    Well, day 4 since my 80 mg shot and I feel much better. To the point where I'm actually wondering whether I should just stick with once a week injections or really should switch over to 2x a week. I think I will probably stick with the plan, and suspect that if I let this play out I'll start...

    So, I took my first dose at my new Drs. office on Monday - 80 mg. I didn't really talk about switching myself to 40 mg/2x a week, but I don't think he cares. It had been more than 2 weeks since my last 200 mg dose, and I was really dragging. Lots of fatigue and not great mood. It has now...

    Yeah, hopefully I can get him to focus on symptoms. I just completed two set of tests to get a sense of the yo-yo on my current 200 mg/2 weeks program. Three days after injection my total T was 1596 and E2 was 75. Two weeks after injection, I was at 425 total T and 27 E2. It’s no wonder I...

    Yeah, agreed. I do think my current dose may be too high though -- if I were completely take over and do self treatment, I would have dropped to 40 or 50 mg/2x a week anyway. I'll see how this goes for a month or two and then pull the plug if he's too conservative and then just manage it...

    Thanks all. I met with a local TRT clinic. The guy actually was pretty good and is willing to prescribe test C for at home injection, which my insurance would pay for. He's recommending I move down from 200 mg every 2 weeks to 80 mg a week, because he thinks my my recent tests were too high...

    Thanks to you both. I don’t know why I defaulted to subq. Hadn’t thought about it, I guess. Smaller needles and a little easier? But I take your point about not changing too many variables at once. I like my PCP for everything but TRT. Have been with him a long time. Kind of dreading...

    New Member looking to take control of my TRT from a PCP who doesn't provide many options. My main question concerns dosage, but I'll take any advice I can get. Sorry if overly wordy below -- I'm not entirely sure what's relevant. 57. I was diagnosed with low T in June. I had symptoms --...

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.
