Freedom has had very low content results. I just talked to Commander about this. They also got busted showing a result outside of the equipment's capabilities. They are legit IMO, just having some issues.
ILS has had issues, but I think they will get things in order. All these new labs I would be very wary of.
Kovera has recently made a major investment and is getting things set up. @commander is way ahead of me on this one he has tested at most of them. Just about everyone who has tested at Freedom has had a far different result when the same batch (some from the same pack) is tested at a different lab when it comes to content. Endotoxins at these labs are a total joke IMO. None of the videos of these labs show an environment to get accurate results. Sterility for sure; that's easy but not endotoxins. The truth is, it's nearly impossible to pass sterility and have toxic endotoxin levels. In that case, the endotoxins are very likely from the lab environment itself and not the peptide.
One thing to look for outside of testing is moisture in the vial; you can see this when material sticks to the sides of the vial. That is a problem in terms of degradation and creates an environment for bacterial growth. I would use those first, IMO, and filter. Nothing to go crazy over, but it's likely crappy manufacturing in an uncontrolled environment. We would see this in the nutraceutical space at crappy facilities.
