Manufacturing Flow & Strict Quality Control System
The production of medik8 liquid peptides begins with rigorous raw material screening, where only pharmaceutical-grade amino acids and coupling reagents are selected. The synthesis process employs solid-phase peptide synthesis (SPPS) or liquid-phase methods, followed by multi-stage purification using reversed-phase HPLC to achieve the target purity. Each batch undergoes third-party testing for identity, purity, and stability, with certificates of analysis (CoA) provided. Long-term stability tests under accelerated conditions (40°C/75% RH for 6 months) confirm the product's shelf life and performance. Manufacturing adheres to current Good Manufacturing Practices (cGMP) in ISO 9001:2015 certified facilities, minimizing contamination risks and ensuring traceability from synthesis to packaging.
