About MCR Peptides

Founded in 2025, MCR Peptides was created to meet the growing demand for reliable, high-purity peptides backed by transparent lab testing and responsive customer service. We’re not just a supplier—we’re a partner to researchers across the UK and beyond.

Built for Labs. Trusted by Professionals.

MCR Peptides started with a simple but overlooked need in the research community: consistent access to clean, verified peptides that don’t come with delays, question marks, or quality concerns.

We saw too many researchers relying on unreliable suppliers, vague test results, or generic compounds with no transparency. So, we decided to change the standard.
