The detail

What you should know.

Description

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, used to reconstitute (dissolve) lyophilised peptides.

The benzyl alcohol lets a reconstituted vial be used over multiple days. A research supply, not a therapeutic product.

How it works: The benzyl alcohol is bacteriostatic — it stops bacteria multiplying — so a mixed peptide vial stays usable for around 28 days when refrigerated.

Researched to support: reconstitution, bacteriostatic, essential kit.

Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.

How to use

Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.

Administer: Diluent, usually with an insulin syringe.

Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).

Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.

Research dosing protocols

Used to reconstitute peptides for research:

  • Add slowly down the inside wall of the peptide vial; do not shake.
  • Let the powder dissolve for 10–15 minutes.
  • Refrigerate the mixed vial and use within about 28 days.

Side effects & safety

Frequently described

  • Injection-site stinging (from benzyl alcohol)

Less frequently described

  • Local irritation

Precautions / risks

  • Not for neonates (benzyl alcohol)
  • Keep sterile / capped between uses
  • Research use only

Digestive effects are the most common and usually ease with gradual titration. Scientific reference only, not usage instructions.

FAQs
What are peptides?

Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.

What's included in my order?

The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.

How do I reconstitute the peptide?

Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.

How should I store it?

Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.

How are peptides administered?

Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.

When do effects appear?

It varies by peptide and protocol. Some are researched over a few days, others over several weeks.

Do I need to see a doctor?

A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.

Are your peptides tested?

Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: you are welcome to have a vial independently tested — contact us first so we agree the laboratory. If the result doesn’t match the label, we reimburse the cost of the test and either replace the product or refund it.
