I found that IM with 1/2 inch length produced for me similar total t values as sub-q. I was around 28 percent bkdy fat at the moment. So its a bit tricky with the BF how deep the needle goes. Now Im leaner, but I dont wanna try things and mess around.@ivkonst2017, I know you believe in IM only. In your experience, what is the minimum needle length you can use and still get into muscle? I think 1/2" in the thigh would work, but wonder what you have found.
For me the perfect size needle for IM is 3/4 inch 27g.
About your issue, sorry that I dont remember but what is your progesteron value? My provider believes most folks who cannot tolerate optimal amounts of testosterone have sub-optimal progesteron. He gives as optimal for most men 1-4nmol/l but still vastly varying according to receptors sensitivity. Basically he determines whether progesterone is ok by the symptoms. According to him even guys with less than 1nmol/l have enough for their needs if the tolerate optimal amounts of test and/or thyroid.
