# About — Recovery & Tissue Repair research peptides | Kai Peptides > What Kai Peptides is, how it selects and cites literature, and its editorial independence. A reading desk for recovery and soft-tissue research — not a vendor, not a clinic. An independent literature digest on peptides studied for recovery and tissue repair. How it works, where the citations come from, and what it does not do. ## A reading desk for research peptides Kai Peptides is an independent editorial project. It covers three research peptides — BPC-157, GHK-Cu, and KPV — that are studied in the context of everyday recovery and soft-tissue repair. The site is a literature digest: it reads peer-reviewed research, summarizes findings in plain language, cites sources, and presents the evidence the way the evidence actually is, including the gaps and cautions. This is not a vendor. There is nothing to buy here. This is not a clinic. There is no medical advice, no human dosing guidance, no treatment protocol. The site is for people who want to understand what the published science actually shows before forming a view about any of these compounds. Researchers, curious readers, and people who have encountered these peptides in a health or fitness context and want an honest, source-backed account are the primary audience. The three compounds on this desk were chosen because they share a thematic frame — repair and recovery — but approach it from different mechanistic angles (vascular, matrix, and inflammatory), which makes reading them together more informative than reading any one in isolation. ## Editorial method Every claim on this site is either directly attributed to a specific published study or clearly labeled as anecdotal community-reported experience. Claims are cited by number in brackets; the full reference list, including DOIs and PubMed IDs where available, is on the [references page](/references). Literature is selected by compound and by evidence quality. Primary studies (original research papers) are preferred over secondary aggregators. Where a claim is supported only by preclinical (cell or animal) data, the species is stated. Where evidence is limited to a single research group, that limitation is noted in the text — as it is for both BPC-157 [2] and GHK-Cu [11], where much of the foundational work originates from one or two investigators. Where evidence conflicts or is weak, the text says so rather than resolving the ambiguity in favor of a positive claim. Citations are not post-hoc decorations. They are the only reason any factual claim on this site belongs here. DOIs and PubMed links are included so readers can check the source directly. If a claim cannot be cited to a primary or systematic source, it does not appear on this site — except in clearly labeled anecdotal sections. ## Independence and disclaimers Kai Peptides has no commercial relationships with peptide vendors, compounding pharmacies, or any entity that sells the compounds described here. It receives no compensation for reviews, mentions, or links. The site does not link to any vendor, supplier, or purchasing source. None of the content on this site constitutes medical advice. None of it constitutes a recommendation to use any of the compounds described. None of the compounds covered — BPC-157, GHK-Cu, or KPV — is approved by the US Food and Drug Administration as a medicine for human use. BPC-157 is not eligible for pharmacy compounding under 503A rules (US). BPC-157 is prohibited in competitive sport by the World Anti-Doping Agency. GHK-Cu as a topical cosmetic ingredient has a legal status in the US and EU; injectable or systemic use is unapproved and experimental. KPV is a laboratory research chemical with no approved human use. Readers who have medical questions about any condition or who are considering using any compound described here are encouraged to consult a licensed healthcare provider. --- An independent reading desk for what the peer-reviewed literature actually says about recovery and soft-tissue research peptides — citations in, conclusions out, nothing sold.
