1/2 inch insulin pins for B12

hey u all..

is it ok to use a half inch insulin pin to inject my b12??

i think the only place where i could maybe get deep enough is my delt...i dunno??? could i do it anywhere else??


thanks

Ive injected tren with that in my arms, delts, and quads. Just press hard enough so your skin dimples in. Thatll earn you an extra 1/4-1/2"
