I've never heard of the patches, but its interesting. I do know that I get tingling when my B12 is low. I had it yesterday, I was just about due for my shot (about 2 days early) I had my husband give me the injection, and the tingling stopped within an hour or so. So I guess the shots work pretty fast.
