What the certificate states.
The certificate of analysis carries the same batch number as the label on the vial. If a different number appears there, it is not the certificate for your goods — in that case please contact us before using the batch.

- Measured value in percent
- Identity (ESI-MS)
- Measured mass against nominal mass
- Peptide content (AAA)
- Measured value in percent

Weighing and
dilution.
Two calculators for the day the vial is on the bench. The molecular mass is that of GLP-5; everything else you enter.
Amount to weigh
Mass (g) = concentration (mol/L) × volume (L) × molecular mass (g/mol)
Dilution
Concentration (stock) × volume (stock) = concentration (target) × volume (target)
The calculators are an aid, not a release. The certificate of analysis for the batch supplied is what governs.
