This happened to me last month and I still don’t totally know what to make of it.
Honestly I only picked PureSci Labs because they were cheapest and had a working checkout, which in hindsight is not a great way to choose.
Support at PureSci Labs was actually pretty decent when I had a problem, which surprised me given what I’d read.
Worth noting there’s an Index Score of 89 for them published, which is more than I expected honestly.
Happy to be told I’m wrong, genuinely.

Testing desk here. Every specimen page links the full laboratory report, including the method and the lot. If something in one of them is unclear, say which and we will explain it.
Mass spec gives you molecular weight, which confirms identity but says nothing about whether the sequence is correct. Two different peptides can share a mass.
Exactly right.
Watched three vendors rebrand under new names after bad results. Check domain registration dates.

ha, fair
Was just about to ask this.
