im sorry to break this too you, but cels c.o.a.'s aren't worth anything.
they have posted those coa's and outside sources have tested their products and found them to have one or more discrepency in what their coa's claim.
in the words of chris farley, tommy boy "anyone can slap a gurantee on a box, hell, you want me to take a sh it in a box, and gurantee it, I will"
aside from the products that have been tested as less than pure, what is important is user results.
it may not be cels fault, they are a non us company, with no office in the us, so it could be their suppliers, and the lab that test the products.
if mdrol was from the same source as orig sd, and they had a labeling error, then why did they never fix it? like you said, mdrol wasn't a fly by night supplement, it was around for a long time, and the labeling issue, never got fixed.
maybe because it is illegal to intentionally mis label a product......just saying.....
