So this is an early review of SF's Hex 450. I pulled up through a 20g needle and it was a little slow. This worried me a little bit but then I remembered this is 450mg per cc. The inject went better then the pull. I shot, aspirated, then injected. Really went well and smooth. So far no PIP. I will update tomorrow about PIP(or lack of, hopefully) and try to continue to note the changes as best I can in my physique and strength.
