Quarterly Research Update
Imperial Peptides Q3 2026 Update: July–September
Our Q3 update covers the latest additions to the Imperial Peptides UK peptides catalogue, new batch-specific COAs, the return of Bacteriostatic Water, Tesamorelin availability and the launch of our new research peptide bundles.
Expanding Our UK Peptides Catalogue
Q3 saw another addition to the Imperial Peptides research catalogue with the introduction of PT-141 10mg.
Our approach to catalogue expansion remains selective. Rather than continually increasing the number of products available, we focus on additions that complement the existing research range while maintaining our standards around documentation, testing and traceability.
PT-141 10mg
PT-141 10mg joined the Imperial Peptides catalogue during Q3, supported by batch-specific third-party testing and documentation.
New Batch Releases & COA Updates
Independent testing and batch documentation continued throughout Q3, with two new batch-specific Certificates of Analysis added to our public COA library.
| Product | Batch Code |
|---|---|
| PT-141 10mg | PT10-06/28 |
| TB-500 5mg | TB5-07/28 |
For researchers comparing UK peptides suppliers, access to batch-specific documentation provides an additional layer of transparency when reviewing research materials.
Our available Certificates of Analysis remain publicly accessible through the Imperial Peptides COA library.

In our Q2 update, we reported disruption to Bacteriostatic Water supply following the ongoing Hospira shortage and changes affecting imports.
During Q3, we successfully completed our supplier transition and secured a new source, restoring availability of Bacteriostatic Water 10ml through Imperial Peptides.
Supply restored: Bacteriostatic Water 10ml is now available again following the completion of our supplier transition.
Maintaining continuity of supply was important, but not at the expense of our standards. The transition was completed with continued emphasis on product verification, quality control and supply-chain traceability.
Securing the new supplier closes an important operational project from Q2 and gives us a more stable foundation for Bacteriostatic Water availability going forward.

Q3 also saw GHRH (1–44) Analog Amide 5mg become available directly through Imperial Peptides, bringing Tesamorelin research back into our main catalogue.
Consolidating the product within the main Imperial Peptides store makes it easier for researchers to access the product alongside our wider peptides UK catalogue and associated research documentation.
GHRH (1–44) Analog Amide 5mg
Available directly through Imperial Peptides for research use only, with supporting product information and documentation accessible through the product page.
Introducing Research Peptide Bundles
Another Q3 development was the launch of our new Research Peptide Bundles collection.
Selected research products are now available together with an automatic 3% bundle saving, creating a simpler way to order pre-selected combinations from the Imperial Peptides catalogue.
Bundle & save 3%: Our new bundle collection brings selected research products together with an automatic saving compared with purchasing each item individually.
The introduction of bundles is part of our wider effort to improve the purchasing experience while keeping individual product information, batch documentation and research-use-only positioning clear.

Q3 was less about rapidly expanding the catalogue and more about strengthening the infrastructure around it.
Restoring Bacteriostatic Water supply, expanding our public COA library, bringing Tesamorelin research directly onto Imperial Peptides and introducing a simpler bundle system all contribute to the same objective: creating a more reliable and transparent research purchasing experience.
As Imperial Peptides continues to grow, our focus remains on clear documentation, independent testing, product traceability and consistent communication with researchers.
Looking Ahead to Q4
Moving into the final quarter of 2026, our focus remains on strengthening the Imperial Peptides platform rather than expansion for expansion's sake.
We will continue reviewing demand across the catalogue, publishing new batch-specific testing as inventory changes and looking for opportunities to improve the research purchasing experience while protecting the standards that underpin the brand.
Thank you to everyone who has continued to support Imperial Peptides throughout Q3.
