What to ask before trusting a claim.

Four checks that answer different questions

Identity asks: is the material what it says it is? Amount asks: how much of it is present? Quality asks: what else is in the product? Clinical evidence asks: what happens when people use it? Passing one check does not pass the others.

A “99% purity” headline does not by itself establish the amount in a vial, freedom from microbes, freedom from bacterial toxins, stability during shipping or a health benefit. Each claim needs a test that actually measures it. A clear report states what was tested and what was left out.

Read a batch report with care

A certificate of analysis, often shortened to COA, is a report about a sample. Check that its product identity and lot number match the item being discussed. Look for the lab name, report date, methods and actual measurements. A certificate with no matching batch link has limited value.

A chromatogram separates substances and shows signals from the detector. A purity percentage usually describes a particular calculation from that test. It does not mean that every possible impurity was detected. An identity test, an amount test and a sterility test answer separate questions.

A laboratory report is useful evidence within its scope. It does not authorize a drug for sale or prove that a person will benefit. Be cautious if one small report is being used to support every claim on a sales page.

People add another layer

Age, pregnancy, health conditions, allergies and other medicines can change risk. When reliable human studies are limited, a neat list of “common side effects” may create more confidence than the evidence allows. An absence of reported problems is not the same as careful monitoring.

Tell a qualified health professional about products you have used, including the exact label and where they came from. If you feel unwell, seek care. Keeping the packaging and batch details can help with assessment and reporting.

What the Canadian regulator says

Health Canada’s April 2026 advisory names TB-500 among unauthorized injectable peptide products offered online. It warns about serious harm and says that “research use only” labelling does not make these products safe for human use. Use the original advisory for its full advice and updates.

Take these questions to a qualified professional

A good conversation starts with your actual goal. For an injury, that may mean a diagnosis, pain control, movement, sleep and a safe return to normal activity. Ask which options have evidence for your condition and what would count as progress.

• What is causing my symptoms?
• Which tested options fit my diagnosis?
• Which claims about this exact molecule have human evidence?
• What facts are still missing about this product?
• What signs mean I should seek urgent care?
