Bacteriostatic Water – Research-Grade Solvent

Bacteriostatic Water – Research-Grade Solvent

Bacteriostatic Water (0.9% w/v benzyl alcohol in sterile 0.9% sodium chloride) is a preservative-containing aqueous solution engineered to support stable, low-microbial-growth reconstitution of lyophilised research peptides and compounds. It has become a standard solvent in preclinical peptide pharmacology due to its extended in-use stability (≥30 days post-penetration), compatibility with hydrophobic peptides (e.g., TB-500, Ipamorelin), and reduced aggregation vs. plain saline. This Bacteriostatic Water is supplied sterile-filtered and endotoxin-tested for research reproducibility and assay integrity.

Supplied in sterile, single-use glass vials to maintain sterility and stability.

What is the Bacteriostatic Water Research Solvent?

Bacteriostatic Water is a 0.9% (w/v) benzyl alcohol solution in sterile 0.9% sodium chloride, conforming to USP <1> Bacteriostatic Water for Injection monograph specifications — for research use only. It is not licensed as a medicinal product in the UK, but supplied under MHRA’s Guidance on Unlicensed Substances for Research (2024) as a laboratory reagent. NovaVitality’s formulation is:

• Filter-sterilised (0.22 µm)
• Endotoxin-tested (<0.5 EU/mL)
• Filled in Type I borosilicate glass vials (USP <660>) with bromobutyl stoppers
• Validated for peptide solubility and stability (see Reconstitution Compatibility Matrix)

Supplied exclusively for laboratory research, assay development, and educational purposes (RUO) — not for human or veterinary therapeutic use.

🔬 Note: While USP-compliant in composition, this product is labelled “For Research Use Only” and does not carry a UK marketing authorisation. It is not a medical device under UK MDR 2002.

Scientific Identifiers

Usage and Reconstitution

Bacteriostatic Water is designed for peptide stock solution preparation in research settings:
✅ Ideal for: TB-500, Ipamorelin, CJC-1295 No DAC, PT-141, Melanotan 2
⚠️ Not recommended for: GHK-Cu (benzyl alcohol may interfere with Cu²⁺), highly hydrophilic peptides (e.g., DSIP, Semax — saline preferred)

Protocol:

1. Swab vial stopper with 70% ethanol.
2. Insert sterile needle, withdraw desired volume (e.g., 1 mL for 10 mg peptide).
3. Add slowly down vial wall — do not inject directly onto lyophilised cake.
4. Gently swirl to dissolve (no vortexing for aggregation-prone peptides).

Post-First-Use Stability:
– 2–8°C, protected from light — ≤30 days (per USP <1> bacteriostatic claim)
– Room temp — ≤7 days
– Discard if cloudiness, particulates, or colour change occurs.

🛒 Auto-paired with peptide orders — adjust quantity before checkout.

Bacteriostatic Water: Key Research Applications

This solvent enables reproducible, low-microbial peptide handling in:

• Long-Term In Vitro Studies
  → Stable peptide stocks for 72h+ cell assays (e.g., cAMP, β-arrestin)
  → Reduced contamination in primary neuron/microglia cultures
• Pulsatile In Vivo Dosing
  → Multi-day ICV/IP dosing regimens without daily reconstitution
  → Consistent pharmacokinetics in GH pulse studies (e.g., CJC-1295 + Ipamorelin)
• High-Throughput Screening
  → 96-well plate-ready peptide dilutions (≤0.5% BA final = non-toxic to cells)
  → Compatibility with automated liquid handlers (low foaming)
• Stability-Critical Peptides
  → Enhanced solubility for hydrophobic sequences (D-2-Nal, D-Phe, fatty-acid moieties)
  → Reduced aggregation vs. acetic acid/saline for cyclic peptides (e.g., PT-141)

⚠️ All vials are for laboratory reagent use only — not medical devices.
