    Saw this just a day ago and reposted here. Probably went unnoticed.

      Cool. What metric are we using?

        Krause Analytical. They have been bad mouthed here by some with 2nd or 3rd party semi-negative comments. None that I’ve seen were first hand knowledge. Below is from a SubStack article ranking testing labs. Krause was ranked 5th, above Kovera, ILS, and TrustPoint.

        ——————————————————-
        Krause Analytical has established a strong reputation for peptide identity, purity and quantitative testing, becoming a familiar name within the independent research peptide community.

        Although it maintains a lower public profile than some of the higher-ranked laboratories, its reports appear regularly across the market and its services remain closely aligned with the practical needs of peptide researchers and suppliers.

        Its visibility is also enhanced through its role as one of the independent analytical laboratories used by the Finnrick testing platform, extending the reach of its analytical work to a broader community of researchers seeking third-party verification.

        Rather than relying on a highly visible public brand, Krause has built its reputation through consistent analytical performance, steady market adoption and its contribution to independent peptide testing.

        Current assessment: A dependable peptide-focused laboratory with growing recognition, consistent market adoption and an important role in supporting independent peptide verification.

          @mikebricker I have a sneaky suspicion that that article may be turned on its head in the near future. By the way, I have no horse in this race i just want to see labs do their job and test at a high level. If Krause is accurate with their testing I am all for spending 60-70pct less. No Vanguard is interesting in that article and Freedom while we all know about them. Essentially an AI produced article with a ranking based on nothing. The author simply could have used each lab and tested vials from the same batch and compared results. Maybe we will see someone do that in the near future. hmmmm

              @BeeKind except ILS isn’t accredited for peptides. Their ISO is for cannabis so this isn’t even a valid chart you have here.

                  @mitchmiller it is valid because they are ISO accredited - that's what that means and they DO NOT have a peptide scope- as shown on the chart. No one is accredited for peptides.

                    nice 30k ft view but how do we tell who is "best"? Like if we just want all of our tests results to come in at 99.5% or better we are best to use Freedom I feel. If we want legit critically tested product that we may or may not use on our very own lab rats, I want an unbiased lab that will give it to me straight with no bullshit.

                      But again, who are we going to decide is RIGHT if we send the same product from a kit to all the labs? The only way to ensure they get the same product is to literally have them all taking product to test from the same vial. I think even lately we have seen that different vials in the same kit can give varying results.

                        LOL @ ILS being a measuring stick for anything. They are an absolute mess of a lab and have all of their employees working virtual. Absolute worst customer service and testing turn time of any lab in the field. Bottom of any list is the only place they should be.

                          @Stevepep ive heard a similar rumor

                          Accumark is very questionable.

                          ILS....has issues

                          Freedom.... im done with them.

                          Trustpointe is solid.

                            @BeeKind exactly.

                            the ISO 17025 accreditation is just a general lab standard. Its not hard to get and it has no bearing on a labs ability to test peptides.

                                @mikebricker Krause results vary by who was running the lab that day.

                                Send them the same batch of reta 3 weeks apart and you get a 20-30% difference in mass. They usually test lower on mass numbers than most labs. Their entire identity is around finnrick which is an entirely different discussion.

                                  @Randy Thanks. I’ve seen the past complaints about the mass differences. And my peps always seem to be about 5 to 10% low in mass. So a 10mg posted will come back 9.3 to 9.7mg. But they do ID correctly and give purity correctly. And they’re consistent with mass.
                                  When you guys ran mass through the various labs weren’t the differences well over 10%?

                                      @Randy exactly, a low of 10.1mg and a high of 12.9mg. That’s over a 20% differential….

                                        I like Dustin and probably watch him field a dozen or more technical questions weekly by other lab people and he is always very dialed in.

                                          I am pretty involved in the lab community and follow most of the lab owners as they discuss lab things. In order of how I trust them based on their knowledge and experience.
