it was reformulated a couple of years ago, i did come across the new ones 3 or 4 years ago and it is different. the bottles look different, too. the new one has a clear cap, the old one is copper.
the new stuff doesn't do it for me.
if you want to get rid of the big old bottle you're talking about, i'm sure we can work something out.
please p.m. me, if you're interested.
