There's a big chasm between how many buyers view the buy/test process, and how it works in reality.
We go in thinking we want to buy what's already been third-party tested and we know the results.
In reality, all that matters (and it's no guarantee of consistency anyway) is what is from the same batch (usually a run of "canning," meaning mixing the API raw material with fillers, adding colored caps, and lyophilizing them).
By the time something's been third-party tested, the vendor is almost always shipping the next batch (or later); additionally, the salesperson is not with the inventory and has no control over which batch ships (although they'll happily lie to you about it).
Add to this the fact that most vendors won't use meaningful batch numbers or dates, won't change cap colors with each batch, will print out small runs of kit labels with recent dates, regardless of the batch, etc. etc. etc. and it's a very frustrating scenario. But still generally worth relying on third-party testing rather than jabbing blind.
Where third-party testing really matters is to get a sense of the vendor overall. There have been some who sold zero-peptide vials...how did they handle those post-sales? There have been some who usually overfill by a significant margin ... do you want to use your kit and adjust based on "feelz" if it might be 30% overfilled?
There are third-party testing communities which you should join and support financially (even if you haven't bought the specific product being tested). The easiest one to start with is Flying Purple Pep Guild ... I'm not sure if link-posting in the Public Square sub-forum is allowed.
