Lab companies all have different labs ranges and units of measurements, Labcorps Free T reference ranges for a guy in his mid 40’s is 6.8-21.5 pg/mL, ranges are higher for a 20 year old (9.8-26 pg/mL), other lab companies have completely different ranges and use other units of (pmol/L, ng/dL) measurement.
Sorry dude, that won’t be enough testosterone! You more likely need 100-160mg weekly split up once or twice weekly. I would just slam on the brakes and talk to your doctor and request an increase in dosage or not bother with TRT until you find a competent doctor or you will end up lower than your pre-TRT levels.
As it stands now your doctor has probably never prescribed TRT and can only lead to more problems down the road if he is unwilling to learn. If none of your doctors will listen to reason, you may need to seek a competent doctor privately that specializes in this area of medicine.
You will not find anyone injecting 50mg weekly! I’m injecting 96mg weekly split up every 2 days which gets my Total T to 500 ng/dL and more importantly Free T levels are at the top of the reference ranges.
I would also request you test SHBG preferably before you start TRT or at least on your next set of lab work which needs to include Total, Free T and estrogen. These are the four labs needed to check or make changes to your TRT protocol.
