Well, I gotta say that thus far, Avanti and Omega are the only reputable sources and I can't tell a difference once I get Omega's into solution. My wallet can tell the difference though

I like the transdermal thing!
For those of you who are wondering how to tell what is what quickly, the C.A.S. number (the bracketed set of three sets of numbers, in this case [97281-47-5]) and the purity are the way to tell. C.A.S. stands for Chemical Abstracts Service and the C.A.S. gives a number to every single chemical that exists in every salt form and every isomer form, just for the purpose of helping folks distinguish what is what.
Only [97281-47-5] is the stuff Lipostabil is made from, and the purity has got to be in the high 90% range. Other C.A.S. numbers and purity below 95% is NOT in any way comperable to Lipostabil!
You would think Avanti is making this stuff from the yolks of chickens that lay golden eggs based on price, but, I still don't have the solution thing down pat, so if you know the best way to solublize Omega's, please post the answer (my yahooo account won't be able to take too many answers)
I don't want to endorse Omega except that they really are the only source other than Avanti, unless you all know something I don't. And the price difference is SO big and Omega is definitely legit.
They were also happy to order other chems for me, as in various Androstene this that and the other. So long as I agree to use them for research and they are not specifically DEA listed, they order them in 98% to 99.5% purity and GUARANTEE their products which are the real thing. Scientific stuff...
Like I said, if you all know of some other source for real Phosphatidylcholine let me know. I will test it out in comparison with Avanti and Omega and let you know. It is a bit tough getting Omega's soluble enough for use so a new supplier with it solvated in amps could be cool... But the application solvation method in the last post is working good...
Thanks!
