I'm not that experienced as any of your mentioned guys but have been in the field for close to 20 years. From my own personal experience I'm leaning towards the same outcome as you mentioned here. On 100mg/week I'm right at the top of the range with my TT and cFT. I feel good, libido is ok, sleep is great, body composition changing in regards to my diet manipulation and everything seems to click. With the way my body is responding I def don't need more and even likely that less will be even better. So something to try in the future. Before starting TRT i had barely in range cFT and still felt good, libido was ok, erection good, etc, so wanted just to see if raising my FT would help anything besides athletic body composition which at this point seems like the biggest benefit together with more masculinity and maybe decisivness, if I can say so. Not sure about actual cognitive function performace as I'm still in process of gathering data and figuring it out.
