Peptide Purity Drops Fast — What Causes It?

Moisture exposure is the biggest destroyer.

Light exposure slowly degrades certain sequences

Impure solvents during synthesis drop purity from day one.

Toxins or metals from bad labs mess with stability

Oxygen exposure oxidizes sensitive amino acids.

Bacteria or endotoxin contamination accelerates breakdown

Repeated freeze thaw cycles kill potency

Long shipping times hot climates purity death combo
