Tesamorlin

We use HPLC and/or Mass Spectrometry to make sure the peptide is what it says it is, with a clear look at purity and any major impurities we would want you to know about.

This helps us understand how much actual peptide is in the vial, separate from things like water, salts, or counterions, so the batch information is more useful and honest.

We check for bacterial endotoxins because cleaner documentation matters, especially for researchers working with sensitive cell culture or in vivo settings.

Additional vials from the same lot can be compared against the primary sample, giving another layer of confidence that the batch is consistent from vial to vial.
