In most jurisdictions, you can get boxes if insulin needles without Rx. In USA, at Walmart or SAM’s Club, get their house brand “ReLion”. Around $13/100.
Injecting SC EOD will provide very smooth T levels, less spiking. Then the TT, FT and E2 lab results are much more meaningful. Do labs on the off-day, always the same so changes in labs are not changes in lab timing.
50mg twice a week is OK, there will be some peaks, do labs half way between injections.
SC provides for smoother T release, smaller peaks and shallower troughs.
