A purity number is not a promise. Here is what it is.

Start with the identity of the sample and the testing organization. Then inspect the method, date, units, and result. A report without a clear product or batch connection may not tell you what was tested in relation to the item you are considering.

• Identify the product, sample or batch reference.
• Locate the laboratory, date, and test method.
• Check the units and what the result is intended to establish.

Identity asks what a substance is. Amount asks how much is present. Purity describes a result under a particular analytical method. One answer cannot stand in for all three, and none independently establishes a benefit for a person.

• Check whether a percentage is being presented without its method.
• Do not read a purity percentage as a probability of benefit.
• Look for evidence that addresses the actual claim, rather than a nearby technical fact.

Clinical studies differ in their design, participants, interventions, and outcomes. Compare the actual study population and treatment with the claim being made. A study may measure a symptom, a biological marker, or a longer-term outcome; these are not interchangeable.

• Identify the population, study design, and comparison group.
• Check the intervention, duration, and outcome measured.
• Read the limitations and adverse-event reporting, not only the conclusion.

FDA approval relates to an evaluated drug and its intended use. A research label, a facility reference, or a test report does not establish that approval. Compounded drugs are not FDA-approved. Product classification belongs in the decision alongside the scientific information.

• Separate a finished product from research about an ingredient.
• Identify the exact approved use when an approval claim is made.
• Discuss clinical suitability with a qualified clinician.
