I read many studies before I got on trt and from what I read, the formula from the scientists was about 8 x the weekly dose was the AVERAGE ng/dl result over the period. It’s a non-linear decay, so it really peaks, then comes down quickly, so people don’t notice when they’re testing troughs.
so, that lab seems very normal for your dose, to me. Maybe +100 ng/ high or so, but it’ll vary each time you test it.
