Peptides are created in laboratories using a precise, step-by-step process. Scientists link amino acids — the building blocks of proteins — in a specific order to form each peptide.

Specialised equipment ensures accuracy and the finished peptides are purified, tested for quality, and freeze-dried into a stable powder for safe storage and use.
