I don't know it all but, I figured the BW would last longer because the ba in it kept it from growing bacteria etc. Maybe it's the BA that causes it to degrade faster...And then I have to ask why would such a high percentage of gh companies included directions that specificaly say not to use BW.
I think what's being missed here is the preservative = BA. It stays true to its name (preservative) and doesn't degrade, it extends the life. That means the protien GH, or rather the chain of 191 amino acids remain intact (preserved) longer. Of course degradation is the inevitable break down process of the acid chain. This is where you keep losing me.
Anyhow, as for companies sending sterile water out instead of BW, it's more of matter of safety than it is degradation, special concerns with respect to IV administration in particular. I can provide info if needed.
Perhaps Big-A can provide additional information not provided in that thread?
