Certificate of analysis
We don't publish a brand-wide spec sheet and call it a “COA.” The certificate you receive references the actual lot number stamped on your vial — with the raw chromatograms attached.

Know your compound
BAC water is sterile water with 0.9% benzyl alcohol mixed in as a preservative. That preservative is what lets you pull from the same vial again and again without it going bad.
Benzyl alcohol is bacteriostatic — it stops bacteria from multiplying in the vial, which is why a single container stays usable for about 28 days after the first puncture. That makes it the standard solvent for dissolving lyophilized (freeze-dried) peptides in the lab.
For research use only — not for human or veterinary use.
The research
The published findings behind this compound — the headline numbers, in plain terms, each cited to source. Preclinical results are directional (animal / in-vitro) and shown for context, not as therapeutic claims.
Because benzyl alcohol is bacteriostatic, one bacteriostatic-water vial supports repeated withdrawals for about 28 days after the first puncture in standard handling studies.

In-use window under standard bacteriostatic-water handling
The formulation standard uses 0.9% benzyl alcohol by volume — the bacteriostatic agent that keeps bacteria from multiplying in the vial between uses.

In a lab dentin-matrix assay, a preservative-class agent (benzalkonium chloride) lowered matrix metalloproteinase (MMP) enzyme activity relative to untreated substrate.

In environmental models, preservative-class benzalkonium compounds adsorbed onto polyethylene microplastics and raised measured toxicity — a lab caution, not a use finding.
