This is the video that helped me learn how to inject How To Inject Testosterone - YouTube it's very detailed I suggest you follow it.

You draw with one needle then inject with another.
You should definitely buy some aromasin just in case and the first sign of gyno you get you use it!
I also suggest you obtain and use hcg.
Being on cycle is the easy part, keeping the gains after you discontinue the use is a bitch,remember that!

Good luck bro!
