Our THD-C serums are carried in olive squalane, which means applying vitamin C after copper peptides isn't just a sequencing preference - it's actively supporting peptide delivery
When available, COA or testing documents should be reviewed before laboratory use to confirm identity, lot details, and analytical information relevant to your research workflow
These typically involve reconstituting the peptide in a small volume of sterile saline (not bacteriostatic water, due to benzyl alcohol irritation) and then transferring it to a nasal spray bottle
