If something was HPLC tested, does this mean it's the real deal?... I mean, If what it says on the bottle should be whats in the supplement?
It also depends on whether the test occurred on incoming ID, or was a pre-post finished product test. There are many different contexts/permutations as far as saying something is "HPLC-Tested"- I am assuming this means in the context of finished product testing- but in reality, really does not tell you ****- I could take a random capsule off my desk, and say it is HPLC tested, but it is still a random capsule off of my desk- if there is no frame of reference- it doesn't really tell you anything.
As a rule of thumb, I would say if it was for substances where there are known monographs/standards, yes, very accurate. HPLC is great for this type of ID- but if it is botanical substances- maybe not...
