Bacteriostatic Water

Dragon Pharma Bacteriostatic Water — Sterile Solvent for Injection

Dragon Pharma Bacteriostatic Water is a sterile, pyrogen-free solution containing 0.9% benzyl alcohol. This specialized solvent is engineered for the safe reconstitution and dilution of lyophilized peptides, growth hormones, and other parenteral medications.

The antimicrobial preservative inhibits bacterial proliferation in multi-dose vials after initial puncture. This makes it an essential safety component for any protocol involving reconstitutable compounds.

Overview

Bacteriostatic Water consists of sterile water for injection combined with 0.9% benzyl alcohol. This preservative system prevents microbial growth without interfering with the stability of most peptide and protein molecules.

Lyophilized compounds such as human chorionic gonadotropin, growth hormone, and healing peptides require dissolution before administration. Plain sterile water lacks preservative protection and becomes a bacterial breeding ground within hours of vial access.

The benzyl alcohol content maintains solution integrity for up to 28 days after the first needle penetration. This supports accurate, repeated dosing across extended protocols without contamination risk.

Dragon Pharma manufactures this solvent under strict aseptic conditions. Each batch meets pharmaceutical standards for sterility, pyrogenicity, and preservative concentration.

Benefits

• Antimicrobial Protection: The 0.9% benzyl alcohol content inhibits bacterial colonization, safeguarding multi-dose vials against contamination between administrations.
• Peptide Stability: Gentle solvent chemistry preserves the structural integrity of fragile peptide molecules during reconstitution and storage.
• Multi-Dose Safety: Supports repeated vial access over 28 days without the rapid degradation associated with unpreserved sterile water.
• Versatile Application: Compatible with human growth hormone, gonadotropins, insulin-like growth factors, and virtually all lyophilized injectable compounds.
• Precision Dosing: Enables accurate concentration calculations, allowing users to achieve exact micro-dosing with standard insulin syringes.

Main Features

• Sterile, pyrogen-free water for injection
• 0.9% benzyl alcohol preservative system
• Designed for multi-dose vial reconstitution
• Compatible with peptides, hormones, and biologics
• 28-day stability window after initial vial puncture
• Pharmaceutical-grade manufacturing and packaging

Ingredients

Each milliliter contains sterile water for injection and 9 mg of benzyl alcohol as the antimicrobial preservative.

The solution contains no additional active pharmaceutical ingredients, buffers, or salts that could interfere with peptide stability or biological activity.

All production batches undergo sterility testing, endotoxin screening, and preservative efficacy validation prior to release.

How to Use

Cleanse the rubber stoppers of both the solvent vial and the lyophilized compound vial with isopropyl alcohol. Allow the surfaces to air dry.

Draw an amount of air into the syringe equal to the volume of solvent required. Inject this air into the Bacteriostatic Water vial to prevent vacuum formation during withdrawal.

Draw the desired solvent volume into the syringe. Slowly inject the solution down the inner glass wall of the peptide vial, avoiding direct stream contact with the lyophilized powder.

Swirl the vial gently until complete dissolution occurs. Never shake vigorously, as mechanical agitation can denature delicate peptide structures.

Store reconstituted products under refrigeration at 2–8°C unless otherwise specified. Label the vial with the reconstitution date and discard after 28 days.

Dosage

Bacteriostatic Water is not pharmacologically active and carries no therapeutic dosage. The volume used determines the final concentration of the reconstituted compound.

Adding 1 mL to a 5000 IU vial of human chorionic gonadotropin yields 500 IU per 0.1 mL. Adding 2 mL yields 250 IU per 0.1 mL.

Select the dilution volume based on the desired injection volume and dosing precision. Lower concentrations permit finer micro-adjustments with standard insulin syringes.

Side Effects

Benzyl alcohol hypersensitivity is rare but possible. Discontinue use immediately if rash, pruritus, or respiratory symptoms develop.

Improper aseptic technique during reconstitution can introduce pathogens despite the preservative. Always use sterile needles and avoid touching exposed rubber surfaces or needle tips.

Using plain sterile water instead of bacteriostatic solution for multi-dose applications creates significant infection risk. This is the primary safety concern in home reconstitution protocols.

Safety Information

This product is intended exclusively for the reconstitution of injectable medications by qualified adults under appropriate supervision. It is not suitable for intravenous injection in neonates or individuals with benzyl alcohol sensitivity.

Always employ strict aseptic technique during vial access and reconstitution. Wash hands thoroughly, utilize alcohol swabs, and never reuse needles or share vials.

Discard any reconstituted product that appears cloudy, discolored, or contains particulate matter. Do not use beyond 28 days after initial vial puncture.

Store unopened vials in a cool, dark environment. Avoid freezing or exposure to excessive heat, which can compromise sterility and preservative efficacy.

Keep out of reach of children and pets. Benzyl alcohol ingestion can be toxic.
