Been trying to cut and I've been upping the cardio somewhat. I've been compensating for the catabolism as best I can with glutamine, but BCAAs were recommended as well. I didn't really plan on getting any, but I was in a Hi Health here in AZ and they had a two for one thing going on their house brand, so I picked some up....$28 or so for two 60-tab bottles.
I don't really take a lot of supps; multis, anti-ox/ala, protein, that's about it. But I've always heard that amino acids can be a help while cutting. I'm sure you could find them just about anywhere at a decent price.
