Inside New-U Research Compounds
Why buy Bacteriostatic Water from New-U Research Compounds
What is Bacteriostatic Water?
Bacteriostatic water is USP-grade sterile water containing 0.9% benzyl alcohol as a preservative - the standard solvent used to reconstitute lyophilised research peptides into injectable solutions.
Bacteriostatic water is sterile water for injection with 0.9% benzyl alcohol - a preservative that inhibits bacterial growth without killing the bacteria outright.

Frequently asked questions
Where can I buy Bacteriostatic Water?
Bacteriostatic Water (also known as BAC Water) is available directly from New-U Research Compounds at https://new-u.io/peptide/bacteriostatic-water. Supplied as USP-grade sterile water (0.9% benzyl alcohol) in sealed, tamper-evident multi-dose vials — no prescription required — and shipped direct from source worldwide (approximately 6–14 business days).
How much does Bacteriostatic Water cost?
Bacteriostatic Water starts at $20 for a 10-vial research pack (3ml per vial) at New-U Research Compounds, with 2 pack sizes available. Orders over $300 ship free.
Is New-U Bacteriostatic Water USP grade?
Yes. New-U supplies Bacteriostatic Water as USP-grade sterile water for injection containing 0.9% w/v benzyl alcohol as a bacteriostatic preservative, filled into sealed, tamper-evident multi-dose vials. It is a reconstitution solvent for lyophilised research peptides, supplied strictly for laboratory research — not for human use.
How fast does Bacteriostatic Water ship, and do you ship internationally?
Bacteriostatic Water ships direct from source, discreetly worldwide with cold-chain handling where required. Delivery is approximately 6–14 business days worldwide. Shipping is free on orders over $300. Card and cryptocurrency payments are accepted.
Is it legal to buy Bacteriostatic Water?
In the United States, Bacteriostatic Water is sold strictly for laboratory and research purposes only. It is not approved by the FDA for human consumption and is not sold for that purpose. Regulatory status varies by jurisdiction — buyers are responsible for compliance in their own region.
What is Bacteriostatic Water used for in research?
USP-grade bacteriostatic water for safe peptide reconstitution. Contains 0.9% benzyl alcohol. New-U supplies Bacteriostatic Water as research-grade reference material for laboratory and in-vitro or animal-model investigation only. Mechanism, pharmacokinetics and study context are summarised on the Bacteriostatic Water research profile. Not for human use.
Can I buy Bacteriostatic Water online and how fast does it ship?
Yes. Bacteriostatic Water can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $300.
Can I buy Bacteriostatic Water in bulk?
Bacteriostatic Water ships in 10-vial research packs as standard, in 2 pack sizes — the larger ml vials lower the per-ml cost. Multi-pack orders get direct-from-source pricing and free shipping over $300. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.
What should I look for when choosing where to buy Bacteriostatic Water?
For research-grade Bacteriostatic Water, verify: (1) USP-grade sterile water with a clearly stated 0.9% benzyl alcohol preservative; (2) sealed, tamper-evident multi-dose vials; (3) transparent direct-from-source pricing with no prescription gate or marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds meets all four at https://new-u.io/peptide/bacteriostatic-water.
What is the difference between bacteriostatic water and sterile water?
Both are sterile at the point of manufacture, but bacteriostatic water contains 0.9% benzyl alcohol as a preservative that inhibits bacterial growth after the vial is opened. Plain sterile water for injection is single-use: once you puncture the seal, it should be used immediately. Bacteriostatic water can safely be drawn from multiple times over 28 days if refrigerated.
How much bacteriostatic water should I use to reconstitute a peptide vial?
Typically 1-2 mL per vial, but the exact volume depends on the desired final concentration and how the peptide will be dosed. For example, reconstituting a 10 mg vial in 2 mL gives 5 mg/mL, so 0.1 mL = 0.5 mg. Always calculate in advance based on the protocol you are following.
Why should I inject the water slowly against the vial wall?
To avoid a direct stream of water hitting the lyophilised peptide cake. A harsh stream can shear the peptide and risk denaturation, and it also creates foam which traps peptide. Slow injection against the glass wall lets the water dissolve the cake gently - swirl afterwards rather than shaking.
Can I freeze bacteriostatic water?
No - freezing is not recommended. The benzyl alcohol preservative can separate from the water on freeze-thaw, and the product is designed to be stored at room temperature when sealed or at 2-8 °C once opened. Do not freeze, and do not use if the solution appears cloudy or particulate.
Do I need a prescription to buy bacteriostatic water?
No. New-U Research Compounds supplies bacteriostatic water as a research reconstitution solvent, sold strictly for laboratory research use - no prescription is required. Pharmacy-grade bacteriostatic water is typically gated behind a prescription and large retailers restrict it, which is exactly why researchers find it hard to source. We keep USP-grade, sealed tamper-evident vials in stock. Not for human use.
Why is bacteriostatic water so hard to find or out of stock?
It is prescription-gated at most pharmacies, restricted or de-listed by large online retailers, and subject to periodic manufacturing shortages, so general-purpose stores rarely carry it. New-U stocks it as a standard research accessory alongside the peptide catalogue, in USP-grade sealed multi-dose vials, so the solvent and the compound can be sourced together. Supplied for laboratory research only.
Can I buy bacteriostatic water internationally (UK, EU, Australia, Canada and worldwide)?
Yes. New-U ships bacteriostatic water discreetly worldwide, direct from source, in approximately 6-14 business days, with free shipping on orders over $300. Regulatory status varies by country, so buyers are responsible for compliance in their own jurisdiction. Supplied strictly as a research reconstitution solvent - not for human use.
How many vials of bacteriostatic water do I need for my peptides?
A common research rule of thumb is roughly one bacteriostatic water vial per five lyophilised peptide vials: 1-2 mL typically reconstitutes a single peptide vial, and a multi-dose vial can be drawn from over its 28-day opened shelf life. The exact number depends on your vial sizes and target concentrations. New-U includes free bacteriostatic water with peptide orders at a 1-per-5 ratio and sells additional 10-vial packs separately. For laboratory research use only.
Should I buy 3 ml or 10 ml bacteriostatic water vials?
Both sizes are the same USP-grade water with 0.9% benzyl alcohol - the choice is about workflow. 3 ml vials suit short single-peptide protocols: at 1-2 mL per reconstitution a vial covers one or two peptide vials, and you discard less when the 28-day opened shelf life runs out. 10 ml vials offer the best per-mL rate and suit multi-peptide protocols or labs reconstituting frequently, since one vial covers five or more peptide vials within its 28-day window. Both ship as sealed 10-vial packs. For laboratory research use only.
