So you do notice an immune system benefit then. Thats good to know. Ive always read it is good for this but never personally monitored it closely enough to know that it did or didnt. Like I said I have a ton of it but only use it for the tren/heartburn thing. Next time I feel a cold coming on Ill throw it in and pay attention to see if it helps me in the same manner. I never felt like it did anything to improve my post workout recovery but thats me personally.
