Cornerstone articles
The BEL library
Six cornerstone readings create a useful journal without crowding the commercial pages.
GLP-1, GIP and glucagon: how to read receptor science
Receptors explain a research strategy. On their own, they do not predict an outcome for an individual.
Retatrutide: what research shows, and what it cannot yet establish
A structured reading of the clinical programme, current limitations and the exact meaning of investigational.
GHK-Cu: what copper-peptide research can really tell us
Several distinct evidence steps sit between a laboratory mechanism and a visible change in skin.
Collagen and skin ageing: separating structure, appearance and evidence
Collagen is a family of proteins and a tissue architecture, not a single marketing number.
How to read a certificate of analysis without being impressed by the formatting
Purity, identity, batch number and laboratory: check what the document actually demonstrates.
How to assess a peptide claim: six focused questions
Six questions reveal whether a claim goes further than the evidence supporting it.
Editorial method
How we build a useful explanation.
The point is not to impress with scientific language. It is to make evidence easier to evaluate.
Visible evidence level
Cells, animals, human trials and regulatory status are never treated as equivalent categories.
Explicit limitations
Uncertainty, gaps between molecule and formulation, and unanswered questions are part of the conclusion.
