Megatron, I'm agreeing with you 100% on this. You've been a great help to me in the past. I know this advise is good and commonly given on here. I'm just adding there may be something extra for kirt09 to consider: His trough is going to increase as you've said. Possibly kirt09 might want to ask himself if he feels his dose is adequate at this level (does he feel symptom free?). I don't know kirt09's TT level, but giving blood work with higher T levels, then he needs to give, might result in a reduction of T dose by his doctor. I'm just saying this may be something for kirt09 to consider when giving blood work at 3.5 days after injection. I'm probably being anal, but I would do every thing in my power not to cause a reduction in T dose IF I were feeling good at said dose. In other words I think twice a week injections are exactly the way to go, I just wonder if the timing of bloodwork should be changed. My logic may be off. If I'm wrong just let me know.
