I Checked 93 “Research Use Only” Peptide Stores. 23 Openly Publish Mixing or Dosing Instructions, a Calculator or Health Claims.

On October 9, 2026, I checked 93 research-peptide storefronts for things FDA warning letters cite as evidence that a “research use only” product is meant for people. Twenty-three publish mixing or dosing instructions, a dosing calculator or claims about effects in people. Another 24 list bacteriostatic water. The label has been in federal plea cases since 2013.
