Elliot R. Vance

Research Writer, coaindex.

I write coaindex, an independent reference for people trying to evaluate research-peptide sources before they commit to one. The single hardest problem in this space is not chemistry. It is trust: deciding which certificate of analysis is real, which vendor is worth believing, and which claim is marketing.

My focus is document literacy. A certificate of analysis is only useful if you can read it, so most of my work is about turning a wall of numbers into a decision. That means explaining what an HPLC purity figure actually measures, how a mass-spectrometry identity result confirms what a vial contains, why a lot number on the paperwork needs to match the lot on the label, and how to check whether an independent lab issued a report at all.

How I approach the writing

Every article is built to be verifiable rather than persuasive. I work from primary documents, name the specific checks a reader can run themselves, and flag uncertainty instead of papering over it. If a claim cannot be checked against a lab report or a public record, it does not go in.

  • ✓ Reads and explains third-party COAs (HPLC purity, identity confirmation, lot matching)
  • ✓ Documents vendor red flags and what a closed or reshuffled source means for buyers
  • ✓ Breaks down how common peptide blends are formulated and labeled
  • ✓ Every piece is fact-checked against source documents before publishing
