How to Spot a Weak Health Claim in Thirty Seconds
A short checklist that filters out most of what circulates about peptides, supplements and wellness compounds.

You do not need specialist training to identify an unreliable claim. A handful of structural features do most of the work.
The checklist
Is a specific study cited, or only the word studies? Was it conducted in humans? Was there a control group? Does the mechanism stand in for an outcome — a claim about receptors rather than about people?
Is a single named authority the entire evidence base? Does the claim describe a benefit with no stated limitation or adverse effect? Is the product sold by the person making the claim?
Two phrases that should slow you down
Clinically studied means someone ran a study. It says nothing about design, size, comparator or result. Research suggests is compatible with a single small trial or with an animal experiment.
Neither phrase is dishonest. Both are frequently doing work that the underlying evidence cannot support.
