Just got this and thought I would share it.

Anyone know why the guideline for not injecting 2’’ from the belly button. Heard this, but not the reason. Is it because the belly button is scar tissue?

I believe the two reasons are that there is more hard connective tissue around the belly button and that it is much less of a fatty layer beneath your skin with more blood flow.

Thanks.
