Would it be advisable to take both DCP and Brite together? Redundant? Too much heat? Or bad*ass stack?
That's a lot of heat, but it's not redundant at all.
DCP increases activity of PPAR/Peroxisomes, which both beta-oxidize fat as well as shortening their chains to facilitate escort into the mitochondria to also be burned. This is one of the BASE mechanisms for fat burning (there are several I covered in my Guide to Fat Loss thread).
Quite separate is BRITE's mechanism, which causes white fat cells to become beige/BRITE cells. This forces them to take their fat stores and generate heat, which in our modern lifestyle is wasteful since we have climate control, but it also EXTREMELY costly in terms of energy. Fat loss is pronounced, and through an entirely different mechanism from DCP (and my other products).
Both products will burn fat in different way and, at least, produce an additive effect.
