I'll check on my other PC - I might have some useful info stashed there.
But in the meanwhile, the 3 for 1 deal @ Purtian's is a great deal - almost a lifetime supply.
Bottom line from my personal experience - Poly 80 is easy to use, supposedly helps increase the effectiveness of Minoxidil, is inexpensive, might help you, and won't hurt you.
I use it when I can. Just another weapon in the arsenal.
