Research guides
General technical background on research peptides — analytical methods, formats, storage and UK regulation. Education only: these pages are not claims about the material we sell, and nothing here is usage guidance.

Every field on a peptide COA explained — batch numbers, RP-HPLC purity, MS identity — and the red flags that matter.
AnalyticsPurity and identity are different questions. What each technique measures, what it cannot see, and why credible QC needs both.
AnalyticsWhy a 99% purity figure does not mean 10 mg of peptide in a 10 mg vial — counter-ions, water content and mass balance explained.
HandlingWhy freeze-dried peptides are stable, how they degrade, and the temperature, light and moisture conditions that preserve them.
ChemistryFrom resin to lyophilised vial: the Fmoc synthesis cycle, why crude peptides need purification, and where impurities come from.
ComplianceThe regulatory category research peptides actually sit in — and what a compliant UK supplier will and will not do.
BuyingWhat volume buying should require — same batch, HPLC/MS COA, UK stock — before you scale a catalogue order.
ComparisonSequence identity, why one name is unambiguous and the other is not, and the COA evidence that settles which molecule is in the vial.
BuyingA due-diligence checklist for buying research peptides in the UK — batch COAs, MS identity, company records and dispatch practice.
HandlingWhat lyophilised and non-lyophilised actually mean — and why stability, weighing accuracy and shipping favour the freeze-dried solid.
ChemistryThe Fmoc SPPS cycle at protocol depth — resin and linker, piperidine deprotection, coupling reagents, the Kaiser test, cleavage and workup.
ComplianceWhere the Human Medicines Regulations 2012 draw the line between a lawful laboratory reagent and an unlicensed medicine — for buyer and supplier alike.
ChemistryThe classical solution-phase method set against the solid phase — where each wins, how hybrid routes combine them, and what the route does and does not tell you.
