Custom Peptide Synthesis: Process and Quality Controls

Custom peptide synthesis uses solid-phase synthesis to construct user-defined sequences. Chemists verify each step via in-process testing, while post-synthesis quality control uses mass spectrometry and HPLC to confirm purity tiers.

FDA-Approved Peptides: What Approval Actually Means

While semaglutide and insulin are approved drugs with validated safety data, peptides like BPC-157 and TB-500 are not. Understanding the difference between drug approval and compounding eligibility is critical for patient safety.

Decoding Purity Claims in Research Peptide COAs

A purity percentage on a label is not evidence; it is a claim. High-purity research peptides require verification via third-party Certificates of Analysis (COAs) that detail HPLC and mass spectrometry results. This reference explains how.
