About BluePeak
A UK research chemical supplier built around one idea: publish the paperwork and let the buyer decide.
What we do
BluePeak Peptides supplies lyophilised peptides, blends and laboratory consumables to researchers in the UK and internationally. We hold stock in a UK warehouse rather than drop‑shipping from overseas, which is why orders placed before 2pm leave the same working day.
How we source
We buy from a small number of vetted synthesis partners rather than spot‑buying from whoever is cheapest in a given month. Every incoming lot is checked independently before it is released to stock, and a lot that fails is rejected rather than relabelled and quietly sold on.
Why we publish every COA
A purity figure printed on a label is a claim. A Certificate of Analysis naming the lot, the method and the laboratory is evidence. Our full COA library is open — no account, no email capture — so you can read the report for the exact lot before you spend anything.
- HPLC purity analysis on every incoming lot
- Mass spectrometry to confirm identity against the specification
- Endotoxin and sterility screening as separate tests
- Fill and appearance checked before picking
What we will not do
We do not describe what these compounds do in a living organism, we do not recommend quantities, and we do not supply anyone who tells us they intend human or veterinary use. Those are not disclaimers bolted onto the footer — they are the terms on which the business operates.
