I use insulin pins for both test and hCG. Yeah, they dull a bit and drawing the test out can be a bit tedious and time consuming for it's worth it. We don't need a script for syringes or pins in this state so getting my hands on insulin supplies is easy. I've had to use 1mL, 25 gauge needles before and they suck for sub-q injections (hurts like hell) but it still works.

My personal experience with DIM wasn't good either. I used that to control e2 before the adex and I could never get the dosing or the timing right on it.. There are many guys that have had success with the DIM so I'm not suggesting you quit using it but I just hated it.

Honestly, I'll drop down to an even lower test dose down the road if estrogen becomes an issue. The 160mgs you're on right now would be quite high for me. It may be for you too seeing as your free-test is a bit out of range. My free test was really high when I was having e2 problems and bringing that into ranges brought the e2 down with it. But, it is amazing how many TRT docs out there are pretty insistent on the 200mgs/week. I started my therapy with a doc through LowT and they were great but they popped in on 200mgs straight off the bat and was floored when I told them that I'd rather cut my test dosage in half versus taking any more a-dex or aromasin.
