No one is responding because it would have taken all of 3 minutes to find this out for yourself. insulin pins are insulin pins. Do you really want to know the difference in using a 31g compared to a 29g? OK. For me I can't even tell a difference when injecting but if you are worried about enough to ask I would guess your pain threshold sux so you should probably go with the 31g.

Please note that my post said "guess" and not know. I already stated that my guess is that you have a low tolerence for pain because you are concerned with the difference in a 29g pin compared to a 31g pin.
HCG sub-q with a 29g, .5in slin pin. Also done it with a 31g slin pin... no difference. Can't feel either needle, so whatever you get cheaper go with it. No noticeable difference injecting IM vs sub-q either so may as well go sub-q, faster, easier, painless.
