Technically, there has never been found to be a saturation point. By that I mean, the people who were taking BA longer had higher intramuscular levels. There is likely a point where it stops increasing to any significant degree (as it relates to performance). I don’t think you need to load or anything like that. I don’t even pay attention to how much I take. I take 2-5g a day and after a while it is all going to be a wash. The stuff is dirt cheap as it is. If you are worried about price, take 2-3g a day, it will probably be plenty.
