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 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….

@dispensarysupport I saw thats tudz was using vanguard but didn’t know much about them. What places them high up on your list?

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.

@dispensarysupport. be interesting to compare pricing

Disclosure first: I work with Peptheon, so read this as a supplier's answer rather than a neutral
one.On the question itself — the lab's name matters less than whether the report resolves from the
lab's own domain for the batch printed on your box. Three checks catch most of what passes for
documentation: the batch number on the packaging matches the number on the report; the report is
served from the lab's own domain rather than a screenshot somebody posted; and the values come with
units and a method, not a bare percentage.Being straight about our own line: we publish batch documentation only where the manufacturer
publishes a lab report. Nordic Peptides, who make the retatrutide we sell, publish none, so that
product page carries no certificate rather than one we cannot back — send us your order number and
the batch printed on your box and we will request that batch's paperwork and tell you either way
what came back. The retatrutide is sold as sealed manufacturer pens, we ship within the EU only,
tracked delivery with one flat €20.00 fulfillment and delivery fee per order regardless of order

I never have to be honest. I just always guesstimate $200-250 and $400 if you want endo.
