Field Notes

Questions worth following past the headline. Reported explainers on peptide science, regulation, testing, and the research market—primary sources linked, uncertainty left intact.

Testing · Market audit · 11 min read

“7x tested” sounds rigorous. The number tells you almost nothing.

There is no standard 7x or 8x peptide-testing panel. We audited the claim, mapped the tests that actually answer different quality questions, and built a COA checklist that is harder to game.

  • No regulator or pharmacopeia defines “7x tested.”
  • Seven counts can mean seven methods—or five vials plus two assays.
  • A lot-matched COA with methods and results matters more than the multiplier.

Veterinary peptides are racing ahead of the evidence

BPC-157, GLP-1 drugs, thymosin β4 and other peptides are attracting veterinary interest. Here is what animal studies actually show—and why an RUO label does not turn a research vial into a veterinary drug.

  • Veterinary evidence varies sharply by peptide class.
  • RUO labeling does not convert a reagent into an animal drug.
  • Equine competition adds a separate anti-doping rulebook.
