Quick take
most peptide headlines leave out the one detail that changes the meaning.
- These seven checks take under a minute.
The seven checks
- Who says so? A company announcement is not independent. Example: retatrutide phase 3 numbers are company reported.
- Animals or humans? See the BPC-157 evidence gap.
- Which phase? Phase 1 tests safety, phase 3 tests effect in large groups. Investigational means not approved.
- Is it a category or an approval? Moving a peptide to a compounding category is not an FDA approval.
- Is the vote binding? An advisory panel's vote is a recommendation.
- Is it a report or proof? An adverse event report is a signal, not causation, see the FDA numbers.
- Which country? US policy does not apply in Canada, see the Canadian injunction.

Two bonus habits
- Look for the date. Policy here changes monthly.
- Look for who profits. Disclosed relationships are a good sign, and this site discloses that I earn a commission.
Next, apply the same skepticism to vendors with the vendor quiz.
