Lipotropic (MIC) injections
Lipo-B / Lipo-C / MIC / skinny shots / B12 fat-burner shots · Vitamin/amino injectable blends
What it is
Methionine-inositol-choline ("MIC") injectable blends, usually with B12 and sometimes carnitine, marketed as "fat-burning" or "energy" shots in aesthetics and wellness settings.
What human evidence shows
The components are real nutrients with real roles in fat metabolism — and that mechanistic story is the entire pitch. Controlled trials showing MIC injections cause fat loss in humans do not exist. B12 injections help people who are deficient; in replete people the energy effect performs at placebo scale.
Risks
Modest by this catalog's standards but not zero: injection-site reactions, sterility uncertainty in products from unregulated compounders, and niacin-flush or GI effects from some blend variants. The main cost is recurring money spent on a plausible-sounding blend doing what a diet change was doing anyway.
Legal status
US: legitimate versions exist only under pharmacy-compounding rules; anything else is an unapproved injectable.
Evidence base
Not auto-graded. This entry covers several different drugs, or a use the published research was never about, so no single letter honestly describes it. The reading below is real literature — read it against what this page says, not as a score.
