At Provacan we not only have our products tested in house but also 3rd party verified by FERA Science, a UK based ISO 17025 accredited establishment, originally created as the gov't laboratory inside the Department for Environment, Food and Rural Affairs. Needless to say we consider FERA to be the gold standard, there is no higher level of lab testing verification.
'Lab Reports' reports can be confusing to many people, even when you know what to look for. In some cases report data can vary (on the exact same batch of product) depending on the type of testing used, equipment calibration, number of samples used as well as the individual operating the equipment.
With this in mind, it's important to note that even when testing products with an establishment as prestigious as FERA, they do allow for a reasonable discrepancy. When testing even the same batch minor variation in can results can occur. We work with FERA as they constantly improve product testing and consistency protocols.
