About Hatter Labs
Premium Peptide Therapy. Advancing peptide science for human performance, recovery, and longevity.
Our Mission
Peptides are among the most promising frontiers in human optimization. These short chains of amino acids serve as signaling molecules that can trigger tissue repair, modulate immune response, enhance cognitive function, and support hormonal balance. Yet for most people, accessing high-quality peptide therapy means navigating a confusing landscape of unregulated suppliers and unverified claims.
Hatter Labs exists to change that. We source pharmaceutical-grade compounds from premium manufacturers with verified purity above 98%. Every protocol is designed by physicians who specialize in peptide science, and every patient receives education, dosing guidance, and ongoing support.
Whether you're an athlete recovering from injury, someone seeking cognitive enhancement, or a longevity-focused individual building a comprehensive optimization stack, Hatter Labs delivers the compounds and the clinical oversight to do it safely and effectively.
Our Approach
Pharmaceutical-Grade Peptides
Every compound is pharmaceutical-grade sourced with >98% purity, third-party tested and COA-verified for every batch.
Physician-Supervised Protocols
Licensed physicians design and monitor your peptide protocol, adjusting dosing based on your response and lab results.
cGMP Compliant
All peptides are manufactured under current Good Manufacturing Practices in FDA-registered facilities with USP standards compliance.
Custom Stacking
Beyond single peptides: our physicians design multi-peptide stacks targeting your specific goals, from recovery to cognitive enhancement.
Meet Our Medical Director
Dr. Adrian Kovač
Head of Peptide Science
Dr. Kovač holds dual credentials in biochemistry and clinical medicine, with a Ph.D. in peptide biochemistry from ETH Zurich and an M.D. from the University of Vienna. Over 17 years of research and clinical practice, he has focused on therapeutic peptide applications, publishing in Nature Peptides, the Journal of Peptide Science, and Molecular Therapy.
His work on BPC-157 tissue repair mechanisms and growth hormone-releasing peptide stacking protocols has shaped clinical practice across the field. “Peptides are not supplements,” Dr. Kovač emphasizes. “They are precision signaling tools that require proper dosing, timing, and medical oversight to deliver their full potential.”

Our Values
Evidence-Based
Every peptide we offer is backed by published research. We track emerging studies and update our catalog accordingly.
Patient-First
Your optimization goals drive your protocol. We educate, guide, and support rather than prescribe one-size-fits-all solutions.
Accessible
Peptide therapy should not require a concierge clinic. We bring premium compounds and expert guidance to everyone via telehealth.
Transparent
Full COAs for every batch, clear regulatory status for every compound, and honest communication about what peptides can and cannot do.
