    Journey from Testopel Implants to Weekly Injections

    I had been on Testopel for some time now and just went back to Injections of Testosterone Cypionate every week at 200mg. Basically I feel like crap. I have to see the doctor next week, but I was hoping better results with injections. It feels like I am not injecting anything after week 2. Just...

    I have been Primary Hypogonadotropic all my life, how will HCG help?

    Ok, and this is it. Because I never had "normal" puberty I never had testicles that developed normally. And since I've done nothing but testosterone for last 20+ years, my testis have more than likely shut down. At this stage, I am trying to understand what are the non-atrophy benefits of HCG...

    I have been Primary Hypogonadotropic all my life, how will HCG help?

    I have been Primary Hypogonadotropic all my life, how will HCG help?

    Thanks Vince. I don’t do the victim thing but anyone with our condition is victimized first by the condition they have and second by the medical community. My current endo who administers Testopel has basically asked me to stop pestering him with all these questions and accept TRT as the sole...

    I have been Primary Hypogonadotropic all my life, how will HCG help?

    Thanks this is what I was looking for. Testicular size or fertility is no longer an issue for me. But my sanity is. :) and if HCG helps in the background I will consider it. If anyone else had a good experience with HCG I d like to hear more.

    Testopel transfer to others

    Coastwatcher, where do you inject yourself with the insulin needle? I used to use the monster needles on my thigh and just brings back horrible memories. Can you describe the entire process and what specific brand needle products you use?

    Wow, the story of my life: Dealing with bad doctors who don't understand Hypogonadism and just sticking to old fashioned defunct guidelines. I am so happy I joined this forum.

    Testopel transfer to others

    I used to self administer intramuscular shots to my thigh every 2 weeks. I found the curves of testosterone ups and downs to be very difficult to manage. I switched to Testopel for about 4 years and here is my experience. 1. Convenience: Unlike injections, it does not require a visit or for you...

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
