How Bloom Vitality Sources and Tests Its Products

For researchers procuring peptides and research compounds, supplier quality and transparency are not secondary considerations — they are foundational to the integrity of any research protocol. Compound purity, accurate labelling, and reliable documentation directly affect experimental outcomes. This article explains Bloom Vitality’s approach to sourcing, quality control, and documentation.

Our Supplier Standards

Bloom Vitality sources research compounds from manufacturers with established track records in peptide synthesis for research markets. Our selection criteria prioritise:

• GMP-aligned manufacturing — Suppliers operating under Good Manufacturing Practice principles, with documented quality management systems
• Synthesis purity standards — We target ≥98% purity by HPLC as a minimum threshold for compounds supplied to researchers
• Batch consistency — Each batch is treated as a discrete supply event, with independent testing conducted on each batch before it is offered for sale
• UK-based stock and dispatch — All stock is held and dispatched from the UK, ensuring rapid fulfilment and reducing transit-related degradation risk

Independent Third-Party Testing

Every batch of research compound supplied by Bloom Vitality is independently tested by Janoshik Analytical — a specialist third-party laboratory for research compounds. Testing is conducted independently of our supply chain: samples are submitted directly to Janoshik, analysed by their staff, and results are recorded on Janoshik’s own systems.

Standard testing for each batch includes:

• HPLC purity analysis — Quantitative determination of compound purity as a percentage by high-performance liquid chromatography
• Mass spectrometry (MS) identity confirmation — Confirmation that the molecular weight of the tested compound matches the expected value for the stated peptide

Certificate of Analysis Documentation

A batch-specific Certificate of Analysis is generated for every product batch. Janoshik CoAs include a unique verification reference that allows any researcher to independently confirm the results at verify.janoshik.com — providing assurance that CoA documentation has not been altered between the laboratory and the end researcher.

CoAs are available on request via our Testing & Quality page. We are working towards making batch-specific CoA documentation directly accessible on each product page.

Storage and Dispatch

Lyophilised peptides are stable at a range of temperatures but benefit from controlled storage conditions to maintain integrity over time. Bloom Vitality stores all stock in appropriate conditions and dispatches orders with next-day delivery as standard within the UK, minimising transit time between our warehouse and the researcher’s laboratory.

What We Do Not Do

We do not conduct in-house testing and present those results as independent verification. We do not reuse CoAs across batches. We do not supply compounds that have not passed third-party testing. Transparency in documentation is a non-negotiable part of how we operate.
