I ordered some in early 05 and still have a few packs. It says it expired in March of 07. Is anyone aware if the expiration significantly decreases its effectiveness? I also have some that expires in 09, so I'm ok either way, just wondering if I should trash this stuff that expired a year ago or if it's still worth using? Perhaps it is 90% effective, so 25mgs would only be as effective as 22.5 mgs or is that not how it works?
Thanks.
Thanks.
