That’s up to you – only input I’ll share to help you decide is that sometimes during a time of need, b12 is injected at that dosage on a daily basis for a time. This article shares a typical b12 shot journey. They basically said a 500-1,000mcg shot of b12 is given daily for 1-2 weeks, then once a week for 4 weeks, then once a month (like where you are at) the rest of their life.
So that said, it’s possible that during the hCG diet, which is a more strenuous process going on in your body during this time, that you might stand to benefit from a little additional b12 on a more daily or weekly basis.
My detailed post on lipo and b12 shots shares ladies experiences with these two things in combo with hCG.
