Sterile diluent for laboratory peptide reconstitution

About this compound
Bacteriostatic water is sterile water for injection containing 0.9% benzyl alcohol as an antimicrobial preservative. The benzyl alcohol concentration is sufficient to inhibit microbial growth across multiple withdrawals from the same vial, making it the standard diluent for reconstituting lyophilized research peptides where multi-dose vial use is required.
In a typical research workflow, bacteriostatic water is added directly to a lyophilized peptide vial through the rubber septum using a sterile syringe. The peptide dissolves on gentle swirling. Stored refrigerated, the resulting peptide solution maintains integrity for the published shelf-life of the specific compound.
Sterile filtered, multi-dose vial format. Supplied for in vitro laboratory use only. Not for human or veterinary administration.
Allergen notice: Contains 0.9% benzyl alcohol, a known allergen for some individuals. Researchers should follow standard laboratory safety procedures including appropriate PPE, ventilation, and SDS review before handling.

Effective May 1, 2026
This Shipping Policy describes how Norway Peptides prepares, ships, and delivers Products. By placing an order, Buyer agrees to the terms of this Policy.
Service Area
At this time, Norway Peptides ships only within the United States. We do not ship to U.S. territories or international addresses. We do not ship to P.O. Boxes; a physical street address capable of receiving a cold-chain package is required.
Order Processing
Orders are typically processed and prepared for shipment within one to three business days of order receipt. Processing times may be longer during high-volume periods, holidays, or for orders requiring additional verification.
Cold-Chain Handling
All lyophilized peptides are shipped in temperature-controlled packaging designed to maintain stability in transit. Packaging includes insulated containers and refrigerant gel packs sized to the destination and transit time. Buyer is responsible for inspecting and refrigerating or freezing the Product promptly upon receipt in accordance with the storage instructions on the Certificate of Analysis.
Shipping Methods and Transit Time
To preserve cold-chain integrity, Norway Peptides ships via expedited carrier services, typically overnight or two-day delivery. Standard ground service is not available for temperature-sensitive Products. Estimated transit times are calculated from the date of shipment, not the date of order, and exclude weekends and federal holidays.
Tracking and Delivery
A tracking number is emailed once an order ships. Signature may be required on delivery for some shipments. If no one is available to receive the Product and the carrier holds the package, Buyer is responsible for retrieving the Product promptly to preserve cold-chain integrity.
Damage in Transit
Inspect each shipment immediately upon receipt. If a Product arrives with visible damage, evidence of temperature excursion (e.g., fully thawed coolant where it should remain frozen), or other apparent defect, contact us within seven (7) days of delivery at research@norwaypeptides.com with photographic documentation. We will arrange a replacement at our discretion in accordance with our Terms of Sale.
Lost Shipments
Shipments not delivered within ten (10) business days of the carrier's estimated delivery date may be considered lost. Contact us to initiate a carrier trace. We will work in good faith to resolve lost-shipment claims, including replacement where appropriate.
Shipping Charges and Taxes
Shipping charges are calculated at checkout based on weight, destination, and required service level. Buyer is responsible for any applicable state or local sales taxes.
Address Accuracy
Buyer is responsible for providing a complete, accurate shipping address. Reshipment of orders returned due to incorrect address information is at Buyer's expense.
