These are very similar – the only difference is that MIC shots don’t contain B12, and Lipo shots typically contain all the ingredients of MIC + b12.
I have a very detailed post on Lipo/Mic shots to help you understand it better and also if it’s worth the cost of trying them or not.
Many use them in addition to hCG on their rounds of hCG during P2, and some use a lipo product that Nu Image Medical carries for after Phase 2, during Phase 3, to aid them in stabilization – they call it Ultraburn, and you can add it to your hCG purchase with them and then use it in phase 3.
