H2O is a sterile laboratory reconstitution solution, made of water preserved with 0.9% benzyl alcohol and supplied for laboratory research use only. It is a laboratory reagent, not a peptide compound.
H2O is sterile water containing 0.9% benzyl alcohol as a preservative. It is supplied as a clear liquid. Solutions of this type are commonly called bacteriostatic water and are a standard reagent in laboratory settings that work with lyophilized research peptides.
The benzyl alcohol content is what sets H2O apart from plain sterile water. The identity of the preservative is confirmed for each batch, as shown in the Product Specifications section.
H2O is supplied as a general-purpose laboratory reconstitution solution alongside Peppy Peptides' range of lyophilized research compounds. It is a reagent and has no research activity of its own.
No. H2O is a sterile, benzyl-alcohol-preserved water solution. It contains no peptide.
H2O contains 0.9% benzyl alcohol as a preservative, while plain sterile water contains no preservative.
