    Starting Over on TRT

    Yeah, I realize now it was a terrible protocol. At the time was popular from the book and Dr scally who I see is also not highly regarded now.

    Starting Over on TRT

    I actually don't have a protocol right now. I recently tried a propionate protocol which made me feel good but gave me the worst libido, ed, and sleep I've ever had in my trt experience. Based on this thread advice I may either do a lower starting dose with hcg or a higher more frequent dose of...

    Starting Over on TRT

    I used Bayer for the E and Pfizer for the C. The Bayer felt a little stronger than the Pfizer but again this is totally anecdotal. Both have more of a feeling of energy than the empower.

    Starting Over on TRT

    To be honest the best I remember feeling was 50mg twice a week despite the slightly weak erections. The 100mg a week had my e2 in the single digits but I don't feel any improvement from having high E2 either. I suppose I can dose more frequently but would starting in the 100mg per week range...

    Starting Over on TRT

    Youre not rude or attacking at all. You bring up good points. The only thing about defy is every time I call they tell me to raise my dose and add in all kinds of drugs like AIs, dopamine agonists even though my prolactin is fine, gh releasing peptides even though my igf1 is great, and I want to...

    Starting Over on TRT

    I can do defys original protocol of 70mg and 400iu if you think that's better than 50mg and 500iu twice a week? I was just not sure if that would be too much and I'd like to avoid an AI if possible but I'm not completely opposed to them like some are. I'll definitely do a lot more testing this...

    Starting Over on TRT

    250iu eod which is 17 percent below baseline from that study is still like 875 per week though right? The atrophy isn't good, but also I feel a difference in how I feel without it. I'm not sure if that's a good or a bad thing, but I feel very flat and emotionless without it.

    Starting Over on TRT

    Thanks guys. I know that at one point I was using about 700iu of HCG per week and it didn't raise my estrogen very much. Defy recommended 500 twice. They also wanted 140 a week again but I don't want to start high on both HCG and test

    Starting Over on TRT

    Hello everyone, looking forward to this community and getting some help, this seems like the best and most reasonable forum around for the discussion of TRT. If you want to skip my long history, the questions are at the bottom. History: Tested for low total T (279, 303) at 24 (I'm 32 now). My...

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.
