Again although TT is important to know FT is what truly matters as it is the active unbound fraction of T responsible for the positive effects.
Top it off that we always need to test at the true trough lowest point before your next injection.
You were hitting a whopping TT 1200 ng/dL (100 mgT/week) and robust TT 635 ng/dL (50 mg T/week) and you have normalish SHBG but not sure where it sat on your 100 mg/week protocol.
How many days post-injection on both protocols 50/100 mg T were labs done?
Going to be a big difference in peak--->trough when injecting once weekly.
Need to know what trough FT level you were truly hitting before jumping to any conclusions as to whether your dose of T is possibly too high or too low!
Common starting dose is 100 mg T/week.
Yes some may start on <100 mg/week but it is far from common.
Rare that anyone would be started on 50 mg T injected once weekly and even if the starting dose 100 mg is eventually titrated down most are still injecting more than 50 mg T/week.
