I agree with you (John); that message I referred to originally does sound like a late night infomercial. I did some further checking and found a webpage at: http://ceri.com I'm not exactly sure what to make of it. I can't tell if it's a research effort, a think-tank or a modified Life Extension Foundation. I hope many of you will check out this website and post your thoughts, insights, etc. Any of our group in Mexico that might have knowledge about the manufacturer of the 'Liquid Deprenyl Citrate'; please tell us if you know anything about this or if there is any way to verify anything on the liquid Deprenyl. I would remain dubious unless I could obtain an independent labs' analysis on the exact contents of the liquid deprenyl coming from Mexico. Waiting to hear from everyone... Lisa Carper --
