How do you know....

[bigbench]

How do you know when you underneath the muscle and not just really deep into it? A couple of bodybuilder guys I know, go underneath the muscle ( in the bi's) when the spot inject, but they really can't explain to me how the do it. (They're pretty much idiots). But obviously it works, because they've put on well over an inch on their arms in about 2 weeks and it doesn't look bloated either. It is crisp and hard looking. Just wondering if anyone has had any experience with this before.

Thanx

What are they putting under there? Synthol?

I have no idea of what they're talking about. IM drugs are supposed to be injected INTO the muscle, not underneath.
