Answers to the questions we are asked most often about our research peptides, purity testing, certificates of analysis and delivery. If your question is not covered here, our scientific team is happy to help.
Are research peptides legal to buy in the UK?
Research peptides are not controlled drugs, and buying or holding them as reagents for genuine laboratory research is not restricted in the way medicines are. Supplying or promoting them for human use is restricted: an unlicensed product marketed for people falls under the Human Medicines Regulations 2012. Everything we supply is sold strictly as a laboratory reagent for in-vitro research.
What purity are Peptivitalis research peptides?
A minimum of ≥98% by reverse-phase HPLC unless the listing states otherwise. Identity is confirmed by mass spectrometry, and lyophilised material is checked for water content by Karl Fischer titration.
Do you provide a certificate of analysis?
Yes, for every batch. Certificates are available on request.
How is purity verified?
Purity is verified across independent laboratories rather than relying on a single in-house result. We also source across multiple manufacturers for each compound so that the highest-purity batch available can be selected for release.
How fast is UK delivery?
Orders confirmed before 15:00 GMT on a working day are dispatched the same day. UK deliveries typically arrive within one to three working days, and UK tracked delivery is free on orders over £120.
Do you ship worldwide?
Yes. International orders are dispatched on a tracked service. Customers are responsible for confirming that import of research reagents is permitted in their jurisdiction, and for any duties or import charges applied on arrival.
How should material be stored?
Lyophilised peptides should be stored at 2°C to 8°C and protected from light. Store away from moisture and avoid repeated temperature cycling. Storage guidance specific to each compound is given on the product listing and the certificate of analysis.
