Artyi, 250mg a week sounds a bit high to me. I would probably start with something like 80mg 2x a week. Just from my experience, I was peaking over 1300 TT on 150mg a week. If you can withdraw the test from the ampule with a syringe, you can use that to measure it out into the other syringes and get it pretty accurate. Honestly, if it is a little off, you probably won't notice.
