What this list does not show

Search demand tells you what people are curious about, not what works. Read each peptide's evidence before anything else.

Search interest is not evidence

This list follows what people search for and discuss. It says nothing about how well any peptide works.

Animal results may not carry over

Doses, routes and effects seen in rodents or cell dishes often have no tested human equivalent.

Approval covers specific uses

An FDA approval applies to the conditions and doses on the label, not to every goal a drug is searched with.

Combinations are a separate question

Blends and stacks put several peptides together. Evidence for one peptide is not evidence for the mix.
