Question 1

What is the difference between bacteriostatic water and sterile water?

Accepted Answer

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.

Question 2

How much bacteriostatic water should I use to reconstitute a peptide vial?

Accepted Answer

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.

Question 3

Why should I inject the water slowly against the vial wall?

Accepted Answer

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.

Question 4

Can I freeze bacteriostatic water?

Accepted Answer

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.

Question 5

Do I need a prescription to buy bacteriostatic water?

Accepted Answer

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.

Question 6

Why is bacteriostatic water so hard to find or out of stock?

Accepted Answer

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.

Question 7

Can I buy bacteriostatic water internationally (UK, EU, Australia, Canada and worldwide)?

Accepted Answer

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.

Question 8

How many vials of bacteriostatic water do I need for my peptides?

Accepted Answer

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.

Question 9

Should I buy 3 ml or 10 ml bacteriostatic water vials?

Accepted Answer

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.

Question 10

How do I buy Bacteriostatic Water?

Accepted Answer

Add the Bacteriostatic Water pack size you need to your cart and check out: enter your shipping details, then choose your payment method — cryptocurrency or card — on the next step. Every order ships with its batch Certificate of Analysis (COA). Bacteriostatic Water is supplied strictly for laboratory research use only, not for human or veterinary use.

Question 11

What payment methods can I use to buy Bacteriostatic Water?

Accepted Answer

At checkout you can pay by cryptocurrency (BTC, ETH, SOL, LTC, USDC, USDT and more) or by card, each handled by a dedicated secure payment provider. You choose your method after confirming your order.

Question 12

How fast is shipping, and do you ship worldwide?

Accepted Answer

Yes — we ship worldwide in discreet, unmarked, temperature-stable, tracked packaging. Delivery typically takes 6–14 business days, and shipping is free on orders over $300.
