Expert Voices

Peptide Experts Worth Following

The peptide space is full of noise. These are the credible researchers, clinicians, and educators who do the work — publishing studies, treating patients, and translating real science to real people. We center the expert, not the channel.

Editorial note: This is a curated list, not a paid placement. We list experts based on published work, clinical credentials, and the depth of their contributions to peptide science. Experts appear on shows like Joe Rogan, Moonshots, and Shawn Ryan Show — we reference those appearances as context, but we feature the expert, not the platform.

Dr. Predrag Šikirić

MD, PhD — Professor, University of Zagreb School of Medicine

Academic ResearchBPC-157GastroenterologyPharmacology

Dr. Predrag Šikirić is the Croatian scientist who pioneered BPC-157 research beginning in the early 1990s. He is the principal author of dozens of peer-reviewed studies on BPC-157's effects on gastrointestinal healing, tendon repair, neurological protection, and systemic organ defense. While primarily an academic researcher rather than a public educator, his body of work is foundational to everything the research peptide community knows about BPC-157.

Known For

→Original BPC-157 research and characterization
