Safety Fundamentals

Safety in peptide use begins with source verification. Not all peptide suppliers are equal, and the unregulated nature of the research peptide market means quality varies enormously. Reputable suppliers provide third-party Certificates of Analysis (COAs) showing purity levels (aim for 98%+ purity), identity confirmation via mass spectrometry, and endotoxin testing. Never use a peptide from a supplier who cannot provide current, batch-specific COAs from an independent laboratory.

Sterile technique is non-negotiable. Every injection introduces a potential pathway for bacteria to enter your body. This means using bacteriostatic water (BAC water) for reconstitution, swabbing vial tops and injection sites with alcohol, using a new sterile needle for every injection, and never touching the needle tip. Proper sharps disposal in a puncture-resistant container is both a safety requirement and a legal obligation in most jurisdictions.

Before starting any peptide protocol, establishing baseline bloodwork is essential. At minimum, obtain a complete blood count (CBC), comprehensive metabolic panel (CMP), fasting insulin, IGF-1, and inflammatory markers like C-reactive protein (CRP) and homocysteine. These baselines allow you to objectively track how your body responds and catch any adverse changes early. Consult with a knowledgeable physician before beginning any protocol.
