not IMO. I've done both. It would seem the realease from suq would be slower but it say right o the label for subq or IM only so either should suffice.

sub q is better because it's so easy imo! But if you are injecting it along w/ your gear that I guess it's the same thing cuz it's one less injection.

Really doesn't matter, whatever your comfy with.

Sub-q with an insulin needle works great for me. No pain.

sometimes a sting, but it's really nothing.

Works great for me as well...Can't even feel it.
