How we work with research peptides
Every Spheres Peptides™ research compound is supplied with an independent third-party Certificate of Analysis (COA). We publish the batch number on every vial, allow customers to verify by batch on our COA Verification page, and ship cold-stored to UK laboratory addresses.
The catalogue is grouped into four research-focused categories — Recovery & Repair, Skin, Hair & Cosmetic, Growth & Metabolic, and Performance — to make finding compounds for a specific line of laboratory study faster. GLP-1 related research compounds are handled separately by direct enquiry only, in compliance with UK prescription-only-medicine advertising regulations.
All products listed here are supplied for laboratory research use only. They are not for human or animal consumption and are not intended for therapeutic, diagnostic, weight-loss or performance use of any kind.
Research peptide FAQs
- How are batches verified?
- Each batch is tested by an independent analytical laboratory. The COA reports purity percentage, test date, and identity confirmation. You can view any batch's COA on our verification page.
- Do you ship outside the UK?
- We currently ship within the UK. EU and international research enquiries can be made via the contact page.
- Why are GLP-1 compounds not listed for purchase?
- UK regulations restrict advertising of prescription-only medicines. GLP-1 research compounds are therefore handled by enquiry only on our GLP-1 Research Enquiries page.
- What payment methods are accepted?
- UK bank transfer and PayPal. All prices are in GBP.
