Has anyone heard/or tried the vitamiin b12 and lipo injections to loose weight? do you think it works?

i was wondering if anyone has tried this or have friends that have cause a couple of my friends have said it works for them?
Answer:
Not personally but hear that work, but those are expensive and with high risk of bounce back unless you exercise and diet.

Scam. No evidence that those things work at all.
