Very interesting. You really do wonder what the truth is.. I think the average time I"ve heard is about 3 months. But yes, the stock solution can be frozen for a very long time. Maybe the interferon I used was a different brand name??? Can't even remember. But for me the $12.00 a month was worth it to make sure it was fresh and still potent. sue
