Peptides for Recovery & Longevity: A Beginner's Guide

Peptides are short chains of amino acids that act as signaling molecules in the body. The biohacking community uses them for recovery (BPC-157), tissue repair (TB-500), and longevity (epitalon). This guide explains the science, the evidence gaps, sourcing risks, and legal status, especially relevant for NZ and international readers.

BPC-157: The Complete Guide

BPC-157 (Body Protection Compound) is the most popular peptide in the biohacking and athletic recovery communities. Extensive animal research shows accelerated healing of tendons, ligaments, gut lining, and muscles. Human clinical data is essentially nonexistent. This guide covers the science, protocols, risks, and legal landscape.

TB-500: The Complete Guide

TB-500 is a synthetic fragment of thymosin beta-4, a peptide involved in cell migration, angiogenesis, and wound healing. It's widely used alongside BPC-157 for musculoskeletal recovery. Human clinical data is limited; this guide covers the science, protocols, and risks.

Epitalon: The Complete Guide

Epitalon (Epithalon) is a synthetic tetrapeptide studied for telomerase activation and pineal gland function. Developed by Russian gerontologist Vladimir Khavinson, it's popular in longevity circles despite limited Western clinical validation. This guide covers the science, protocols, and realistic expectations.

GHK-Cu: The Copper Peptide Guide

GHK-Cu (copper peptide) is a naturally occurring tripeptide that declines with age. It promotes wound healing, collagen synthesis, and hair follicle stimulation. Unlike BPC-157, GHK-Cu is widely available in topical skincare — but injectable forms are popular in peptide biohacking for systemic effects. This guide covers mechanisms, dosing, and the topical vs injectable debate.
