Jay Campbell

Self-described "5x international best-selling author" and hormone-optimization/peptide educator, publishing his "GLOW Protocol" (BPC-157, TB-500, GHK-Cu) and a "Wolverine" stack writeup on jaycampbell.com. HIGH CONFLICT OF INTEREST: sells his own "Quantum Peptides" product line plus a paid peptides course and book bundle directly from the same site that carries this content, the most direct commercial peptide conflict of any voice on this site. Added with honest, contested (YELLOW) labeling per site policy: a large following, but content that promotes his own unregulated product line without disclosing the underlying evidence tier.
