We work exclusively with UK-based suppliers who meet our strict verification criteria: they must be registered UK businesses, provide certificates of analysis (COA) for their products, comply with all relevant UK regulations, have secure payment processing, and maintain transparent pricing with no hidden fees.

Certificates of Analysis are laboratory test results that verify the purity, composition, and quality of peptides. All reputable suppliers provide COAs for their products, typically showing purity percentages (usually 98%+), batch numbers, and testing dates. Always request COAs when purchasing research peptides.

We welcome UK-based peptide suppliers who meet our quality standards. Click 'Vendor Affiliate' in the navigation menu to submit an application. We review all applications within 2-3 business days and will contact you to discuss partnership opportunities, commission structure, and integration options.

Payment methods vary by supplier but typically include credit/debit cards, bank transfers, and sometimes cryptocurrency. Each supplier's accepted payment methods are listed on their individual product pages. All our verified suppliers use secure payment processing.

Delivery times vary by supplier and location but most UK suppliers offer next-day or 2-3 day delivery within the UK. Specific delivery options and timeframes are provided on each supplier's website during checkout. All peptides are shipped in temperature-controlled packaging to maintain integrity.

Return policies vary by supplier. Due to the nature of research chemicals, many suppliers have strict no-return policies once products are shipped. However, most will replace products if they arrive damaged or if there are quality issues verified by COA. Check each supplier's return policy before purchasing.

Most lyophilized (freeze-dried) peptides should be stored at -20°C or colder in a freezer. Once reconstituted, they should be stored at 2-8°C (refrigerated) and used within the timeframe specified by the manufacturer, typically 1-4 weeks. Always follow the specific storage instructions provided by your supplier.
