Peptide delivery timelines can be affected by factors related to synthesis, quality control, logistics, and order requirements. Common reasons include:

1, Complex peptide sequences that require additional optimization
2, Low crude purity requiring extended purification
3, Difficult peptide solubility during purification or formulation
4, Additional quality control testing to confirm identity, purity, or content
5, Custom modifications such as labeling, conjugation, or special formulations
6, Re-synthesis if the peptide does not meet quality specifications

Not every delay is avoidable, but transparent communication helps reduce uncertainty and allows you to adjust your plans accordingly.

Each peptide has its specific characteristics. If we have difficulties in completing your peptide or some problems happen during the process of synthesis, we will inform you as soon as possible.
