Research guides
GHK and GHK-Cu: comparing preclinical research
Compare two GHK and GHK-Cu studies: the materials, cell and animal models, measured outcomes and limits of the preclinical evidence.
Peptide research glossary
Understand peptide research terms, including in vitro, in vivo, study design, purity and reported content, with definitions linked to sources.
How to read a peptide research paper
Learn how to read a peptide research paper: examine its methods, sample size, outcomes and limitations, then work through an annotated GHK example.
Preclinical vs. clinical research
Understand preclinical and clinical peptide research: cell studies, animal models, human studies and what each type of evidence can support.
Reviewing a batch report
Match the lot, examine the analytical methods and keep identity, purity and content separate.
