I am almost through an entire tub of Super Plasma Protein right now, and honestly, I can't tell any sort of difference whatsoever. I'm sure the science behind it is sound, and of course it's hard to 'tell' any sort of effect from Whey as well after taking it for years on end, but I have been left underwhelmed. Maybe it's the 5-10g serving I'm taking twice a day, being too limited, but any more and the container would go far too fast and I'm simply following label directions.
