🧪 Synthesis & Quality Assurance
Synthesis Overview
Both Ipamorelin and CJC-1295 are produced using solid-phase peptide synthesis (SPPS), enabling precise assembly of their respective amino acid sequences.
Purification
Each peptide component is purified via high-performance liquid chromatography (HPLC) to remove impurities and truncated sequences prior to blending.
Blending
Following purification, the peptides are combined under controlled conditions to produce a uniform formulation.
Lyophilisation
The blended material is lyophilised (freeze-dried) to yield a stable solid form suitable for storage and handling.
Analytical Characterisation
Each batch is analysed using:
HPLC for purity assessment
Mass spectrometry (MS) for molecular weight confirmation
Quality Assurance
Batches are produced under controlled laboratory conditions and evaluated against predefined quality criteria to ensure consistency, identity, and purity.
Batch Consistency
Standardised processes and analytical verification ensure reproducibility across production batches.
