Interesting...the sample Secant sent me last August (2011), was from lot # 031202. The assay report was dated December 2008. It seems the stuff I got was 4 months older (December 2003 vs. April 2004, if I'm reading the lot #'s correctly) than Tod and John's lot.
I hadn't paid attention to that when I got the sample. In the limited testing I got to do before I got too busy with other things, it certainly seemed to work fine.
