id say it's underdosed.
a 200mg shot of cyp would put me at 1400 3 days after the inj... and that's doing 200mg once every two weeks (legit Phizer doc prescribed HRT).... and with a starting testosterone level of sub 120/100. lol
but, then again, depending on the lab... some labs don't test/register above a certain level.... 2400 is plenty high either way, and possibly on the upper level of what the test will show.
