# About — buyresearchpeptidesonline: An Independent Research Literature Desk

> About buyresearchpeptidesonline: an independent literature digest on GHK-Cu and BPC-157, framed around collagen, ECM and tissue-matrix research. What it is, how it is compiled, and what it is not.

An independent, citation-anchored digest of the recovery peptide literature. Not a vendor. Not a clinic. Not medical advice.

## What this site is — and a note on the name

The name "buyresearchpeptidesonline" is a holdover from an earlier incarnation of this domain. This site sells nothing. There are no products, no shopping cart, no vendor links, and no pricing anywhere on these pages. The name is retained only because the domain is established; the site itself is an independent editorial literature digest.

The desk covers two research peptides studied in the context of **collagen, extracellular matrix (ECM) and tissue-matrix research**: GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper(II) complex, also known as copper tripeptide-1) and BPC-157 (Body Protection Compound 157). Both are synthetic compounds studied in laboratory and animal settings for their potential effects on tissue repair, matrix biology and wound healing. Neither is an approved medicine. This site exists to make the published literature on them legible — organized, cited, and written plainly — not to promote, prescribe or sell either compound.

Content is organized by compound (each has its own dedicated page), supplemented by a comparison page, a FAQ, and a references list that aggregates every source cited across the site.

## Editorial method

Every factual claim on this site is tied to a specific reference from the peer-reviewed literature — identified by a bracketed number (e.g., [1]) linked to the full citation in the [references list](/references). References are drawn from PubMed, ClinicalTrials.gov, NIH databases, and established peer-reviewed journals in dermatology, pharmacology, sports medicine and gastroenterology.

The desk follows three principles in reading and presenting this literature:

1. **Species and model specificity.** When a study used rats, this site says "in rats." When it used human fibroblast cell cultures, it says so. Extrapolation from one model to another — especially from animal to human — is noted as extrapolation, not established fact.
2. **Evidence-level honesty.** Where the evidence is thin, preliminary or derived from a single research group, this site says so plainly. The cautions are part of the record, not a footnote to it.
3. **No doses, no advice.** Study doses and administration routes are reported as they appear in the original research (e.g., "studied at 10 µg/kg in rats" or "given intravenously to two adults in a pilot study") — never as recommendations. The desk does not advise anyone to use, avoid, or do anything with these compounds.

Anecdotal community reports are included on compound pages where the corpus material includes them, always labeled "anecdotal, not clinical evidence" and attributed to community sources rather than the peer-reviewed literature.

## Independence and disclaimer

This site has no commercial relationship with any peptide supplier, vendor, clinic, or manufacturer. It does not accept advertising, sponsorship, or affiliate commissions. There are no links to purchasing sources.

The content on this site is for informational purposes only and does not constitute medical advice, diagnosis, or treatment guidance. GHK-Cu (in its topical cosmetic form) and BPC-157 have very different regulatory profiles — the former is a legal cosmetic ingredient, the latter is a research chemical not approved for human consumption by the FDA or any equivalent body — and readers should understand what they are reading as a summary of published research, not a clinical recommendation.

If you have a medical question, consult a qualified healthcare provider. If you are an athlete subject to drug testing, note that BPC-157 is prohibited by WADA under the S0 category; and verify the current WADA Prohibited List directly before drawing conclusions about GHK-Cu or any other compound.
