Research peptides for Swedish laboratories

Sweden punches well above its population in life-sciences research output, with Karolinska Institutet, Uppsala University and Lund University publishing extensively on metabolic disease, neuroscience and regenerative biology. This drives consistent demand for high-purity research peptides for in-vitro and pre-clinical work.

Domestic Swedish suppliers tend to charge significant markups over factory-direct pricing. Peptx delivers factory-direct pricing to Swedish research addresses through multi-source vetted factory sourcing (independent lab testing) and lean EU fulfilment.

Prices are shown in GBP; your bank or card provider handles any conversion.

Peptx ships to research addresses across Sweden via tracked DHL Express or DPD. Standard transit is 4 to 7 business days from dispatch, with deliveries to Stockholm, Gothenburg and Malmö on the faster end of that window.

All packages ship in plain, unbranded outer packaging with desiccant to maintain lyophilised powder stability through transit.

Peptx stock is backed by independent laboratory results, at typically 99%+ purity (HPLC); the guaranteed minimum varies by compound. Our suppliers are not chosen on a single rating. We weigh independent lab testing.

Independent laboratories test our material on a rolling programme: random quality-control checks, tests on stock we buy in, and testing as part of vetting every new supplier. Certificates are published openly in the COA Library rather than issued per order, so you can read the laboratory's report before ordering, not after. Independent verification is expanding across the catalogue, with further tests in progress across September and October. If you want your specific batch independently checked, send a sample to one of the labs on our testing page (/testing): a result you commission yourself carries more weight than one handed to you by a seller. Any independent lab result below the product's stated guaranteed minimum purity, or a sealed-vial endotoxin or sterility failure, raised within 14 days of delivery, is reviewed under our Purity Guarantee and, where verified, refunded or re-shipped.

All compounds are supplied as sterile lyophilised powder in sealed vials, packed with desiccant, and stored at controlled temperature throughout the supply chain.
