I can't remember the exact numbers without looking them up, but I had been on 150mg per week with weekly IM injections. My trough T level was around 530 my doctor boosted me to 200mg per week and my trough level went to something like 800. That seemed good so I stayed at that. I then switched to EOD sub q and my trough was something like 950 and peak 1260. I have switched back to 150 and I think my levels are something like trough 830 and peak 1050. I've switched back and forth from 150 to 200 a couple of times to see if I can tell a difference. I am now using 150. So frequent injections don't give a high spike but they also don't have as low a trough. Much more stable levels. Doing weekly injections there was a day that I would wake up with extreme anxiety. I don't have that on sq.
