Detailed information regarding our compliance policies, analytical testing methodology, institutional ordering, and cold-chain logistics.
Purivo Biolabs Ltd is a UK-based B2B supplier of analytically characterised peptides. We were founded to bridge the gap between high-volume generic suppliers and highly restrictive, slow-moving institutional chemical catalogues. We supply high-purity, independently tested reference materials to universities, CROs, and commercial research labs.
Yes. All compounds in our catalogue are supplied strictly as analytical reference standards and research reagents (in-vitro). They are not medicinal products, not food supplements, and not intended for human or veterinary administration. As such, they do not fall under the Human Medicines Regulations 2012 when used appropriately in a laboratory setting.
For the compounds currently listed in our standard catalogue, no specific Home Office controlled drug licence is required. However, purchasers must be affiliated with a verified research organisation and assume full responsibility for complying with their institution's COSHH and ethical guidelines.
No. Supply is strictly restricted to verified research organisations, academic institutions, and registered commercial entities. We do not accept orders intended for personal use or human administration, and any account found violating this policy is immediately terminated.
We source our raw peptides globally from synthesis facilities that operate under strict cGMP (current Good Manufacturing Practice) or ISO 9001 guidelines. We do not manufacture compounds in-house. Our value lies in our rigorous independent UK testing, cold-chain logistics, and strict batch-rejection criteria.
We mandate that every batch is independently tested upon arrival in the UK before it is released for sale. We partner with UKAS-accredited analytical laboratories and specialist peptide analysis firms (e.g., Janoshik Analytical). The specific testing laboratory for a given batch is always named on its Certificate of Analysis.
Every batch undergoes Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) to determine purity (minimum ≥98.0% specification), and Mass Spectrometry (MS) to confirm exact molecular identity. Depending on the compound's application, we also perform Karl Fischer titration for water content and LAL assays for endotoxin levels.
Yes. Representative CoAs are available upon request, and you can look up the live CoA for any specific batch using the Batch Lookup tool on our homepage. Every order ships with a physical copy of the batch-specific CoA.
First-time buyers must complete the verification form on our website using a valid institutional email address (e.g., .ac.uk, .edu, or a verifiable corporate domain). Our compliance team reviews these requests within 1 business day.
We accept BACS / Bank Transfer for all institutional orders. For approved accounts, we operate on Net-30 invoicing terms against an official institutional Purchase Order (PO).
We do not enforce a minimum order quantity for verified institutional buyers. You may order a single vial for assay validation before scaling up to larger batches.
Lyophilised peptides are generally stable at ambient temperature for short periods (up to 3 weeks), but we take no risks with degradation. All orders are shipped in insulated EPS shippers with validated cold packs to maintain a stable, cool environment during transit.
UK orders placed and verified before 15:00 GMT are dispatched the same day for next-business-day delivery via tracked courier. International shipping typically takes 3–7 business days depending on customs clearance.
Upon receipt, all lyophilised vials should be immediately transferred to a freezer at −20°C or colder for long-term storage. Detailed handling and storage instructions, along with Safety Data Sheets (SDS), are provided with every shipment.
