Before You Buy: the 12-question checklist

Two pages to read before you pay anyone for a peptide. The questions come from Chapter 13 of The Peptide Companion, and the red flags from Chapter 11.

  • The question that comes before any seller: is there an approved product or a lawful prescription route?
  • How to match a lot number to a published certificate of analysis.
  • The red flags that matter, and the ones that don’t.

Sample question: “Does the seller’s own certificate support what its website advertises?”
