Products received on time, looking good, no prob there. The mots c and kpv are both performing very well. I did however have some gelling issues with the AOD9604. I found it odd that you did not have Acetic Acid Reconstitution solution with it, as its hydrophobic. I queried on line and got back that KOIs AOD can be reconstituted soley with BAC water; so i did (room temp, slow and delicate as should be with disinfected everything.) Nevertheless i got gel inside the vile forming. Im lookimg forward to ordering the AOD again from you guys (because i really liked the other two products) and reconstituting with Acetic Acid this time to see if it doesn't gel this time Do you have any comments, ideas or suggestions for me? Do you think this is a good solution? Will you be providing acetic acid solution for sale in the future?
