PM sent to your misses of me injecting hcg & hgh IM simultaneously into my groin.
honestly i don't have a good reason for doing IM for these other than hearing a couple places that it's better than sub q. IM worked well for my boys on HCG, and I got a tip that IM could be better for IM so that's where i'm at. 4T aka the godfather of gh condones both methods but I think does IM himself.
