Editorial and source policy

Sources are selected for direct relevance to the research question covered by a guide. Original research papers, clinical-trial records, regulator documents and other first-party materials are prioritized when they are available and appropriate to the topic.

A source is not treated as stronger because it supports a product claim. Study design, model, endpoints and limitations remain part of the guide’s explanation so readers can distinguish cell, animal and human evidence.

Each research guide presents a visible source list with the source title, publication, year, direct link and a note explaining its relevance. Publication and update dates are shown on the guide and carried into its Article structured data.

Citations are preserved when a guide is updated. A source link may be corrected or replaced when the destination changes, but a research conclusion should not be expanded beyond what the cited material supports.

Guide conclusions are not based on product price, stock, customer reviews or catalogue availability. Product pages carry the current commercial details; guide pages carry research context, sources and limitations.

Products are offered for laboratory research only. Guide content is educational and is not medical advice, a treatment recommendation or evidence that a catalogue product is suitable for human use.

Corrections to a guide citation, date or source link can be sent to support@puffinpeptides.ca with the guide URL and the specific item that should be reviewed.
