Anywhere you want

I use quads area, but anywhere convenient is fine.

You be doing a subcutaneous (depending on the spot) injection. Probably the only downside is that it takes a lot more technique, as in slow & easy.

Do a little research on SQ/test injections. I takes more work and you have to be careful but the pain factor is less!

I modified my technique a bit, so I'm probably using a combination of SQ/IM.
