Evidence & Science

Look past the mechanism. Ask what was measured, in whom, and whether it changed a meaningful health outcome.

How to read this library

These are editorial evidence descriptors, not a validated grading scale, a ranking of effectiveness, or a safety score. Profiles may include several study types. Regulatory approval is reported separately and applies only to specific products and indications.

Human outcomes

Controlled human trials with demonstrated outcomes in specific populations. This does not establish other uses.

Human research

Human studies exist; size, endpoints, replication and applicability vary. Biomarker changes are not proof of clinical benefit.

Preclinical

Predominantly cells or animal models. Human benefit and safe use have not been established.

Limited / uncertain

Sparse, historical, indirect or insufficiently verified evidence. No dependable conclusion about clinical benefit.

Source transparency & limitations

Bibliographic identities were checked against publication records where available. This selection is not exhaustive, is not a systematic review, and has not been represented as independently clinician-reviewed. Study methods and risk of bias still require appraisal.

Three supplied citations—for Melanotan II, P21 and Selank—could not be independently matched. They remain visibly marked and are not used to assert clinical benefit. TB-500, PEG-MGF and one kisspeptin citation concern related but different molecules; those distinctions are explicit.
