FAQs
Frequently Asked Questions
Are peptides legal in the UK?
Yes — when supplied strictly for Research Use Only (RUO).
UK legislation permits the sale and possession of peptides for legitimate laboratory research purposes. The regulatory framework is overseen by the Medicines and Healthcare products Regulatory Agency, which governs how such compounds may be supplied and presented.
Peptides are not approved for human consumption, and it is not legally permissible for suppliers to market them with therapeutic, medical, or performance-related claims.
What purity should I expect from a UK research peptide?
In the current UK market, the benchmark for high-quality research peptides is:
≥99% HPLC purity, supported by batch-specific analytical verification
This should be confirmed through an independent, appropriately accredited laboratory, with a Certificate of Analysis linked to the exact batch supplied.
Suppliers quoting lower purity thresholds (e.g. 95–98%), or unable to provide verifiable batch-level documentation, typically fall below modern research standards.
What’s the difference between “research grade” and “pharmaceutical grade”?
Research-grade peptides are supplied exclusively for laboratory use under a Research Use Only designation.
Pharmaceutical-grade refers to substances manufactured under strict regulatory controls for use in licensed medicines, typically within a Good Manufacturing Practice (GMP) framework and approved for clinical or therapeutic application.
In the UK, no supplier can legally sell peptides for human use outside of an approved medicinal pathway.
Any use of “pharmaceutical-grade” terminology in relation to research-use peptides should be approached with caution, as it may indicate misunderstanding or misrepresentation of regulatory standards.
How are peptides synthesized?
Peptides are created by linking amino acids through peptide bonds. In laboratory production, this is typically done using solid-phase peptide synthesis, where amino acids are added step-by-step until the desired sequence is formed. The final peptide is then cleaved, purified, and prepared for research use.
Do your peptides include mannitol?
Yes. All peptides contain trace amounts of mannitol, which helps improve stability, solubility, and handling, and protects against moisture-related degradation.
How should peptides be handled and stored?
Allow vials to reach room temperature before opening. Store unused peptides at -20°C or below in a sealed container with a desiccant. Reconstituted peptides should be kept refrigerated and handled using sterile techniques. Avoid repeated freeze–thaw cycles.
What payment methods do you accept?
We accept bank transfers, Visa, Mastercard, and American Express. Payment options are available at checkout.
What shipping options are available?
UK: Royal Mail 24 (£5) and DPD UK (£5.20)
International: Royal Mail or DPD International, selected for efficiency and reliability. Tracking is provided for all orders.
What should I do if there is an issue with my delivery?
Use your tracking number via Royal Mail or the DPD app for updates. Please allow up to 7 days for delivery before contacting support. International shipments may experience customs delays outside our control.
How are your peptides shipped?
All peptides are shipped in lyophilised (freeze-dried) form and packaged to protect against light and environmental exposure. Store according to guidelines upon receipt.
What happens after I make a payment?
Orders are processed automatically once payment is received. You will receive email confirmation and tracking details once your order has been dispatched.
Can I cancel my order?
Do you offer blended peptides?
No. We do not supply pre-mixed blends, as fixed ratios can limit research accuracy. Purchasing peptides individually ensures precise dosing and experimental control.
Can I obtain a Certificate of Analysis (CoA)?
Yes. Certificates of Analysis are available on each product page and can be downloaded directly. All CoAs are for informational purposes only and must not be altered.
