Nupex Peptides Review – A Cautionary Note for UK Researchers

We’ve recently received numerous emails from individuals who mistakenly believed they had placed an order with UK-Peptides.com, only to realise it was through a different website with similar branding.  

To be absolutely clear, UK-Peptides.com is not affiliated with Nupex, peptidestore.co.uk, or any company operating under the name Research Scientific Ltd. These websites are entirely distinct and have no connection to our team, products, or manufacturing processes. Some of these sites appear to employ SEO tactics and imitate layouts to confuse customers.

What Makes Our Products Different?

  • Lyophilised peptides only: We supply research peptides that have been properly freeze-dried, resulting in a solid, stable “puck” formation at the bottom of each vial. This process is crucial for maintaining peptide integrity.  
  • No raw powders: If a product arrives as a loose or fluffy powder, it has likely not undergone a proper lyophilisation process. This may indicate that it is a raw ingredient rather than a completed peptide vial suitable for controlled research.
  • The mannitol myth: Some companies claim their products are “purer” because they don’t contain mannitol. In reality, mannitol is commonly used as a stabilising agent during freeze-drying and helps protect peptide structure. It is not a filler — it’s part of proper peptide formulation.

How to Avoid Imitation Sites

With the growth of the research peptide industry, new suppliers appear regularly. While some may be legitimate, others may lack proper manufacturing protocols or experience. Here’s how to protect yourself:  

  • Verify the supplier’s track record and years in business  
  • Check for batch-specific test data or COAs  
  • Examine the packaging for lyophilised puck consistency  
  • Always double-check the website domain: uk-peptides.com  

If you’re ever unsure, please feel free to email us with a picture of the product and packaging, and we’ll be happy to confirm whether it came from our facility.
