Everyday it was a struggle to try to get my AAS workout partner(doing the same cycle I am) to inject for me. I couldn't do it since it was a 21g needle. He wasn't taking these substances seriously and missing injections. Fed up with him, I finally took it upon myself to get the job done. I bought some 25g needles from Lion and did my first self-injection, deltoid. It slid in great. Now after I stick I can't wait to do it again. Only problem is that I'm having a hard time aspirating when I'm doing side area's like delts, ventroglutes, glutes, and tris. I hold the top of the syringe with my thumb and pull back with my index and middle finger. Any advice?
