I would just stick to pinning the glutes, its a bigger muscle with less nerves. As for the AI ive heard its best run it just to be safe to avoid sides all together. I think you'll be ok without HCG. N why arent u pinning 500mg a weeks, just curious? Anyways keep me posted, ill be starting my first sust cycle within the next 4 weeks. Ive gotten aromasin for an AI and Clomid and nolva for pct.
