Just be careful with the dosage. If you take too much relative to how much you break down dopamine levels will drop in the brain and you'll get a prolactin increase. BCAAS compete with tyrosine, tryptopha, and histidine for entry into the brain.
I do think they work well for cutting (especially with exercise volume). Leucine as a standalone anabolic has not been shown to maintain elevated rates of protein synthesis if given in chronically high dosage. Aim just to replace the loses.
