Not good at math, help :(

So as the title says I suck at math, but just really new to all of this, and needles, measuring, trt, etc.

I got put on 120mg of test cypionate a week. I’ll be doing 2 shots a week. I haven’t received my first order yet it’s on the way, but I wanna be prepared. I chose to do subq shots as I thought they might be less painful, but I might go to intra after my first 12 week check up. Anyway the instructions say 0.3 would be 120 weekly. I guess I just answered my own question, just not sure yet what that looks like on the syringe. Also it since I’m doing subq shots “ no drawing needle available for for insulin needles” is that normal or do I need to order anything else?? Sorry just a noob never done this, but excited to start and feel better!
