This update relates to the availability of bacteriostatic water supplied for laboratory research purposes. Availability and lead times may change as global supply conditions continue to evolve.
Bacteriostatic Water Supply Update
We're committed to keeping researchers informed whenever supply conditions change.
Researchers purchasing peptides in the UK may have noticed reduced availability of bacteriostatic water across a number of suppliers in recent months.
The current shortage is primarily linked to reduced availability of Hospira Bacteriostatic Water together with wider regulatory and customs changes affecting international supply chains.
What's Changed?
Due to the ongoing shortage of Hospira Bacteriostatic Water, our previous manufacturing partners are no longer able to provide consistent supply.
At the same time, recent regulatory and customs changes have increased both sourcing complexity and import costs, affecting lead times across the wider industry.
- Hospira supply remains limited.
- Import lead times have increased.
- International sourcing costs have risen.
- Industry-wide availability continues to fluctuate.
Our Response
Rather than compromising on quality, we have secured a new manufacturing partner to maintain continuity of supply.
Introducing a new supplier requires additional quality checks and batch verification before products are released. Although this has resulted in longer lead times, it ensures our standards remain consistent.
This approach reflects the same principles we apply across our UK peptides range—prioritising documentation, traceability and quality over speed.
We will only release products once they have completed our normal batch verification and quality review process. Maintaining consistency is more important than reducing lead times.
Will Pricing Change?
Unfortunately, yes.
Increased sourcing costs and higher import expenses mean future pricing will be adjusted to reflect the additional costs involved in securing reliable supply.
Our aim is not simply to source the lowest-cost product, but to maintain the quality assurance and batch traceability researchers expect from Imperial Peptides UK.
Thank You
We appreciate the patience and understanding shown by our customers while this transition is completed.
Supply conditions will continue to be monitored closely and further updates will be provided whenever there are significant changes.
Committed to transparency.
Whether discussing testing, documentation or supply chain changes, we believe researchers should receive clear and honest information. Open communication is an important part of maintaining trust.
