Which Testing Labs do you use and trust ?
-
I recently had a vial of Slup332 tested through BTLabs. While I felt pretty confident in my vendor, having ordered numerous quality products from them in the past, this was my first slup332, and I thought Id better be safe. It came back as a fail. What bothered me was the brief email explanation with the report, it said, while the sample absorbs UV light (which apparently it is supposed to do) it contains fillers with no peptide material (I am slightly summarizing, but this was the meat of it). What had me concerned is that Slupp is not a peptide. When I questioned it, they got relatively defensive and just said they have tested thousands of samples in recent months, so they are confident it is not slupp. So, I decided to simply take their graphs and run them through Microsoft Copilot, asking if these graphs could represent the presence of the slupp332 molecule. I got a long dissertation with two different scenario endings, both stating they represent a positive presence of slupp. So, I guess my answer to your topic would be, you may get what you pay for. I chose a cheap option instead of paying up for Freedom or Janoshik, and possibly got a bad test.

Random comment, but this is the only forum I've seen testing labs and vendors put under microscope and discussed critically, which is extremely important for RUO research. Most other forum admins are busy flooding forums with their affiliate vendors' sales or self-promotion.
Thank you @randy!

@pep_researcher 100% agree! It’s concerning, they promote a vendor, get a kickback but delete anything negative about a vendor they are affiliated with, that’s where I lose faith/trust in what they are peddling and their honesty

I've been using Krause Analytical for a while. No problems.

Has anyone heard of Constitution Laboratories? A friend was looking to purchase from a supplier called Veritas Labs, who look to be using Constitution Laboratories for their testing. I have heard of neither.

Oh I agree. It also looks like Veritas is providing a single COA for all mg options for a given pep, so you don't even know if you're getting 30mg or 10mg when ordering.
