Slin pins offer you both a SQ as well as IM injection (depending on how much body fat is present at the injection site).
SQ is typically painless but the absorption rate is slower and it's not advisable to do a large volume injection at any one site at a time. You do more frequent, much smaller injects that are usually pain free. Another benefit is less accumulation of scar tissue.
