Bacteriostatic water: what the benzyl alcohol is doing, and why most packs include it
Bacteriostatic Water 3mL × 2
Bacteriostatic, not bactericidal
The distinction is in the names. A bactericidal agent kills bacteria; a bacteriostatic one inhibits their growth. Benzyl alcohol at 0.9% does the second, which is enough to keep a multi-entry vial from becoming a culture between uses.
It is not a substitute for sterile technique. Inhibited growth is slower growth, not no growth, and nothing in the vial addresses what is introduced on a needle.
Why it ships inside most packs
A boxed pack normally holds the peptide vial and a 3 mL bacteriostatic water vial together, under one batch record. The reason is traceability as much as convenience: the diluent arrives documented alongside the compound rather than sourced separately and unrecorded.
Three packs in the current catalogue are the exception — the GHK-Cu Duo, the BPC-157 + TB500 combination and the 144 IU somatropin pack each hold two peptide vials and no water. For those, the 3 mL vial is ordered separately.
Handling
Water is directed down the vial wall rather than onto the powder, and the vial is swirled rather than shaken. That matters more the larger the molecule: a fifteen-residue peptide is unbothered, while a folded protein like somatropin can be driven to aggregate by agitation.
Bacteriostatic water is supplied as a box of two 3 mL vials and is in stock; it can be added to any order at checkout. Every peptide pack in the catalogue also includes a 3 mL vial in its carton.
