Question 1

What payment methods do you accept?

Accepted Answer

Visa and Mastercard only (no American Express), processed through a trusted PCI-DSS compliant third-party payment provider. Your full card details never touch our servers. A 5% card processing fee applies and is itemised at checkout. We do not accept PayPal, bank transfer or cryptocurrency.

Question 2

Why might my statement show another currency?

Accepted Answer

Prices are displayed in GBP. At payment, the final total is converted to USD using the displayed exchange rate, and your card is charged the exact USD amount shown before you continue to ArgentPlatforms. Your bank may apply its own conversion rate or fees. Stock remains locally held in the UK, dispatched from Central London.

Question 3

Is there a minimum order?

Accepted Answer

No minimum order. All orders ship express overnight nationwide for £9.99 — free on orders over £200.

Question 4

Can I get a VAT invoice?

Accepted Answer

Yes — a VAT invoice is attached to your order confirmation email automatically. If you need a PO-based invoice for an institution, email hello@globalbioresearch.co before ordering.

Question 5

Do you offer bulk or institutional pricing?

Accepted Answer

Yes. Research groups ordering 10+ vials of a single product should contact us for batch-reserved pricing with unified documentation.

Question 6

How fast is delivery?

Accepted Answer

Orders before 2pm (Mon–Fri) dispatch same-day from Covent Garden. Royal Mail Tracked 24 aims for next working day; Special Delivery guarantees next working day by 1pm. A same-day London courier option is available for WC, EC, W1 and SW1 postcodes.

Question 7

How are peptides packaged?

Accepted Answer

Vials are vacuum-sealed, packed with gel cooling in insulated, discreet packaging, and handed to the carrier the same day. Packaging is unbranded externally for discretion.

Question 8

Do you ship outside the UK?

Accepted Answer

We currently deliver within the United Kingdom only. Stock is held locally in the UK and dispatched from Central London. We do not currently offer international delivery.

Question 9

What if my order arrives warm or damaged?

Accepted Answer

Contact us within 48 hours with photos and your order number. Lyophilised peptides tolerate short ambient excursions well, but we replace any order where the cold chain visibly failed — no argument.

Question 10

What does 'lyophilised' mean?

Accepted Answer

Freeze-dried. The peptide solution is frozen and the water removed under vacuum, leaving a stable dry cake. Lyophilised peptides stored at -20°C typically hold specification for 24+ months.

Question 11

How long does a reconstituted vial last?

Accepted Answer

Refrigerated at 2–8°C, most sequences hold for 14–30 days depending on the amino-acid composition. Each product page lists its specific window, and our research library covers aliquoting for longer studies.

Question 12

Do vials come with a Certificate of Analysis?

Accepted Answer

Every order includes the COA for your exact production batch: HPLC purity, MS identity, water content and endotoxin screening. Chromatograms are available on request.

Question 13

What purity are your peptides?

Accepted Answer

Our minimum release specification is 99.0% by HPLC. The rolling 12-month average across all batches is 99.4%. Batches that miss spec are discarded, never discounted.

Question 14

Are research peptides legal in the UK?

Accepted Answer

Yes — when sold and used as laboratory reagents for in-vitro research. They are not licensed medicines and must not be used in humans or animals. Our research library has a full plain-English explainer.

Question 15

Can I buy for personal use?

Accepted Answer

No. Checkout requires confirmation that products are for laboratory research only. We decline orders we believe are intended for human use, and we never provide dosing advice.

Question 16

Do I need to be 18 to order?

Accepted Answer

Yes. All purchasers must be 18 or over. We may ask for age verification on first orders.

Question 17

Is my order confidential?

Accepted Answer

Completely. Discreet external packaging, no product names on the outside, and we never share customer data. See our privacy policy for the full detail.
