What up my peeps!

I have been working on my abs alot but just cant seem to get them HARD, I have heard of some spot injecting in the stomach to increase the muscles and tighten the abs. I remember reading up on HELIOS?

Anyone got advise?

Also, How dangerous or complicated is it for spot injecting in the BICEPS? MY Genetics arent those of a beast and I have trouble getting my byceps to muscle up, my tri's out weight by bi's.

Any advise here as well?

Thanks!
