Regulatory clarity

Approved does not mean everything is approved.

Regulatory approval applies to a defined product, formulation, indication and jurisdiction. An investigational compound is still being studied, while an unverified product may not have established identity, purity, sterility or regulatory oversight.

Last reviewed:

Approved medicine

An approved medicine has been evaluated by a regulator for specified uses and supplied under an authorised label. The approval does not automatically cover every dose, purpose, combination or reformulated product.

Investigational compound

Investigational means the compound or use remains under study. Trial participation involves protocols, oversight and informed consent; it is not equivalent to buying a product sold with a research label.

Compounded preparation

Compounding can serve legitimate clinical needs under applicable rules, but a compounded preparation is not automatically the same as an approved manufactured product and should not be described as regulator-approved unless that precise claim is true.

Unverified commercial product

A label, vial or analytical certificate does not by itself establish that the received product has the claimed identity, concentration, sterility or storage history. Product quality is a separate evidence question.

Questions, answered with context.

Does a high peptide evidence grade mean it is right for me?

No. The grade describes evidence maturity. Product quality, regulatory approval, safety and personal suitability are separate questions.

Can animal research establish a benefit in people?

No. Animal and mechanistic research can support a hypothesis, but the book does not present it as proof of a human clinical outcome.

Which evidence does Volume One prioritize?

The source hierarchy prioritizes regulator-approved labels and decisions, safety communications, trial registries, systematic reviews and primary human research.
