I have been on TRT for about 12 years and am 72 years old. I have been taking Testosterone Cypionate, 100mg every 5 days. I also take a test boost supplement from GNC, 4 weeks on, 4 weeks off. When I took the blood test I had been on test boost for 3 weeks.
I try to plan my blood test on the last day before the next testosterone injection, and that is how this blood test worked out. Results:
Testosterone, Total - 754 ng/dL
Free Testosterone - 134.2 pg/mL
Sex Hormone Binding Globulin - 42 nmol/L
I believe that I have pretty much optimized the benefit of TRT, at least from a blood test perspective. In past annual blood tests my Total Testosterone is typically in the 500’s ng/dL and Free Testosterone is always higher when I am taking a test boost supplement.
Any input is welcome. Sarcopenia is my greatest battle. Old age sucks, except that I am now so weak that I seldom am strong enough to tear anything.
