That may be a tough question to answer since everyone is truly different, I would have symptoms at midrange Free T levels which puts my Total T in the high 300 ranges.
Ask yourself why you went on TRT, was it do to longer recovery times between workouts, weak erections or did you just feel like something isn’t right with you. Depression has other causes besides being hormone related and therefore TRT can’t fix.
It could just be your weekly protocol which a lot of men would have trouble do to not keeping levels steady. The majority of success stories are from those injecting two or more times per week, there are a few outliers though.
