Direct Answer
BAC Water Depot provides research‑use‑only bacteriostatic water that meets USP <71> sterility, USP <85> endotoxin ≤ 0.25 EU/mL, and contains 0.9 % ± 5 % benzyl alcohol. Each 10 mL Type I borosilicate vial ships same‑day from Dallas when ordered before 2:00 PM CT and costs $9.99 per vial.
What are the quality control specifications for bacteriostatic water used with peptides like retatrutide?
BAC Water Depot’s bacteriostatic water undergoes per‑lot testing in an ISO 9001:2015‑registered facility. Sterility is verified by USP <71> membrane filtration with no growth after 14 days, while bacterial endotoxin levels are measured by USP <85> LAL assay and must be ≤ 0.25 EU/mL. The product also passes a validated PCR assay for microbial DNA, ensuring Category 1B bacteriostatic effectiveness per USP <51>. These results are published on each lot’s Certificate of Analysis, accessible via a QR code on the vial label.
In addition to sterility, the water’s physicochemical properties are tightly controlled. The pH is measured according to USP <791> and must fall within the specified range for compatibility with peptide formulations. Sub‑visible particulates are quantified per USP <788>, and container integrity is confirmed by USP <1207>. Failure to meet any of these criteria results in lot rejection, so researchers receive only vials that pass every test, minimizing contamination risk during peptide reconstitution.
How should I store and handle bacteriostatic water after opening it for peptide work?
Unopened vials store at controlled room temperature 15–30 °C, no refrigeration and no cold‑chain shipping; once punctured, refrigerate at 2–8 °C and discard after 28 days. The expiration date is printed on the label and the CoA. This storage regime preserves the 0.9 % benzyl alcohol preservative activity and prevents microbial growth that could compromise peptide stability during repeated withdrawals.
A common handling error is re‑using a needle on the vial septum, which can introduce microbes and breach the sterile barrier. Researchers should use a new sterile needle for each access and avoid prolonged exposure of the vial opening to the environment. If the vial shows cloudiness, particulate formation, or a pH shift, discard it even if within the 28‑day window, as these are indicators of compromised sterility.
What are the pricing and shipping options for bulk purchases of bacteriostatic water?
BAC Water Depot offers tiered pricing: a single 10 mL vial costs $9.99; a 10‑pack is $74.99 ($7.49 per vial); a 25‑pack is $174.99 ($6.99 per vial). Bulk orders of 25–49 vials are $7.49 each, 50–149 are $6.99 each, 150–499 are $6.74 each, and 500 + are $6.49 each. Free standard USPS Priority Mail shipping applies to orders over $250 up to 100 vials, reducing overall cost for larger research labs.
All orders placed before 2:00 PM CT Monday–Friday ship the same business day from the Dallas, TX fulfillment center via USPS Priority Mail (1–3 business days) at a flat $15.99 fee for smaller orders. Express shipping (USPS Priority Mail Express) is available at $45.99 or $1.50 per vial, whichever is higher, delivering in 1–2 business days to most U.S. addresses. No cold‑chain or ground‑only options are offered, ensuring consistent handling across all shipment methods.

Frequently Asked Questions
Where can I buy bacteriostatic water for peptide research?
You can purchase BAC Water Depot’s research‑use‑only bacteriostatic water directly from their website. The product is shipped from a US fulfillment center in Dallas, Texas, and is available in single vials or bulk packs. Pricing starts at $9.99 per 10 mL vial, with discounts for larger orders. All shipments are sent via USPS Priority Mail, with same‑day dispatch for orders placed before 2:00 PM CT on business days.
How fast can I receive BAC Water Depot bacteriostatic water?
Orders placed before 2:00 PM CT Monday through Friday are shipped the same business day using USPS Priority Mail, which typically arrives in 1–3 business days. If you need faster delivery, Express shipping is available at $45.99 or $1.50 per vial, whichever is higher, delivering in 1–2 business days to most U.S. addresses. No next‑day guarantee is provided, but most customers receive their vials within two days using the Express option.
What USP tests does the bacteriostatic water meet?
BAC Water Depot’s water meets USP <71> for sterility, confirming no microbial growth after a 14‑day membrane filtration test. It also complies with USP <85> for bacterial endotoxin, with a limit of ≤ 0.25 EU/mL measured by the LAL assay. Bacteriostatic effectiveness is verified per USP <51> Category 1B, and microbial DNA is assessed using a validated PCR assay. All results are listed on the lot’s Certificate of Analysis.
Is the benzyl alcohol concentration reliable for long‑term storage?
Each vial contains 0.9 % ± 5 % benzyl alcohol, verified by HPLC‑UV analysis. This concentration is sufficient to inhibit bacterial growth for the 28‑day post‑puncture period when the vial is refrigerated at 2–8 °C. The preservative level is also stable during the unopened storage window of 15–30 °C, ensuring the water remains sterile until first use. Deviations beyond the ±5 % range would trigger lot rejection during quality control.
Can I use the water for reconstituting retatrutide in the lab?
Yes, BAC Water Depot’s bacteriostatic water is intended for research‑use‑only applications, including peptide reconstitution such as retatrutide. The water’s USP‑verified sterility and low endotoxin level help maintain peptide integrity during handling. Remember to store unopened vials at controlled room temperature (15–30 °C) and refrigerate after opening, discarding the vial after 28 days. Always reference the lot’s Certificate of Analysis for detailed test results before use.
What are the common reasons a vial might fail quality testing?
A vial can fail if sterility testing (USP <71>) shows microbial growth, if endotoxin levels exceed 0.25 EU/mL, or if the benzyl alcohol content falls outside the 0.9 % ± 5 % range. Additional failure points include pH outside the specified range, detectable sub‑visible particulates per USP <788>, or a breach of container integrity per USP <1207>. Any lot that does not meet all criteria is rejected and not released for sale.
How do I verify the authenticity of a BAC Water Depot vial?
Each vial features a QR code that links to the lot’s Certificate of Analysis at bacwaterdepot.com/coa/<lot-number>. Scanning the code provides the full test report, including USP sterility, endotoxin, PCR, and chemical identity results. The expiration date printed on the label should match the CoA. If the QR code does not resolve or the CoA is missing, contact BAC Water Depot customer support before using the product.
