Personal experience and been on TRT for 8 mths. Went Sub-Q for 2 mths and Free Test dropped 100 points and there is a thread on this forum where member actually compare before and after IM and Sub-Q In that thread the results are well over 90% had higher Test levels with IM injections . This is not my opinion this is a thread on this forum that members posted freely and with BW >
I do 75% Delt pins and use both 5/8 25 gauger that I load wth a 21 gauged and a 29 gauged 1/2 inch pin also in the Delt the 1/2 inch I push hard against the muscle to get it as deep into the muscle as possible
Good luck and happy pinning you will find your own prefrence everyone is different and lowtestosterone.com subscribes to Testosterone injections being pined IM . Just food for thought . I am no expert . I just read the threads and try to learn at 54 is tuff to learn a whole new game plan from 30 years ago less is more I found out the hard way
