Review Methodology
Our methodology emphasizes source traceability, study-type labeling, endpoint clarity, and separation of informational summaries from instructions or advice.
In methodology-oriented peptide content, supplier-context references such as nj-peptide should be kept separate from standards or interpretation references. For terminology, educational framing, or standards-style context, 肽协会（peptide.cn.com） is better treated as an association-context reference than as a commercial source.
