      High Estradiol (81pg/ml) on TRT

      It took several months (6-9) before I really noticed the difference that TRT made for me. I did NOT take any AI's. I began to finally notice strength and muscle gains from my work in the weight room. And finally began to notice fat loss from my diet. I had been doing workouts and dieting well...

      Choose Quest or Labcorp?

      I prefer the LabCorp test results over Quest. I have to drive 2 hours for the nearest LC site whereas Quest is in my small town. I'm gonna stay with LC even though it's more expensive and takes 4 hours of my day.

      Not Gaining Muscle Mass, Not Losing Fat - What's Up?

      I read all those articles - it's the reason I realized I didn't need to be on anastrazole. Thanks for sharing all those, btw. I have a Renpho bluetooth scale and that is what I've been using for over a year. I'm sure it's not as accurate as other methods, but I use it consistently, so it is...

      Not Gaining Muscle Mass, Not Losing Fat - What's Up?

      My goal: lean muscle mass & strength gains. Reality: I've gained 3.6 lbs of lean muscle mass since Nov.2021 - that's less than a 1 lb per month. I started TRT in Nov 2021. (This is currently near the end of Feb 2022 - so about 4 months of TRT) Test. Cyp injections 35mg x2 weekly with...

      Worsening Symptoms, "Dead Penis"

      So, since there's not a lot of clinical trials to base off of, then it would seem we're kind of just learning from trial and error. We are the lab rats! I prefer the subQ over the IM, for sure. I'm fine with daily, but am only doing 3x week currently. Thanks for the enlightening information.

      Worsening Symptoms, "Dead Penis"

      So, why doesn't the protocol START with 10 daily instead? Why do they even bother with 1x week or 2x week? I'm not being a smartass, I'm asking a legit question. I'm working with Defy Medical and I started with 35 x 2/week, but they recently switched to 33 x 3/week instead. Now I'm wondering...

      Worsening Symptoms, "Dead Penis"

      Defy recommended 100 per week, but taking 10 daily is only 70 per week. So you are under-dosing by 30 each week. They recommended 100 per week for a reason, based on your blood work. If they believed 70 per week would work, I'm sure they would have gone with that. Most healthcare professionals...

Free Testosterone

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