There is 78.5% protein measured and 80% claimed on the product, and therefore this measurement falls out pretty nice. Further there are no foreign additives found and the amino acid profile looks good. A deviation of approximately 5-7% is normal and there it falls neatly within.

The post on the forum
Attached a chromatography test of the whey delicious from XXL Nutrition (I use this myself for years and years hence).The preparation is done by means of hydrolysis in order to free the amino acids, followed by ion-exchange chromatography with post-column derivatization (ninhydrin) and in the end detection.
Seen that with the test from Jordi apperently the urgency was not seen how important it is that a sealed jar is sent to the lab (it was promised to 'try', but you just can not do such a test on a sample that one takesfrom the jar himself, too prone to fraud), because such a test is otherwise worthless, I have requested the test myself. This was also the direct reason why I did not pay.
The result contains the amino acid profile of 15 amino acids, and therefore, does not contain all amino acids; the sum of the individual amino acids is not identical to the total (I have to watch my wallet), but all essential amino acids (except tryptophan, this requires a separate isolation method, again took extra $$$) are in the results. The amino acid profile fits well with that of whey protein. A more extensive test with the remaining few amino acids add little to the test in my view, of little importance, and also it costs considerably more money, so.
The lab Nutricontrol is a reliable lab, also well known in the food industry. According to me some board sponsors (XXL? B & f? Powersupplements?) also test their product there.
