Pepceuticals

What Pepceuticals does

Pepceuticals Ltd. is a UK-based peptide synthesis specialist and antibody supplier founded in 1998, headquartered in Enderby, Leicestershire. The company manufactures custom synthetic peptides ranging from research-grade reagents through to cGMP-grade material for pharmaceutical clinical and commercial use, and supplies polyclonal and monoclonal antibodies to life-science and academic customers. Its technology base rests on proprietary synthetic methods, most notably the CLIPS peptide synthesis platform developed by in-house Research Teams, which enables preparation of complex peptide molecules with shorter delivery times while preserving quality, and supports specialized modifications including stapled and cyclic peptides. The company also produces peptide libraries for drug discovery, neoantigen peptides for cancer immunotherapy research, and GMP diagnostic and theranostic peptides.

Pepceuticals operates a B2B sales motion through direct phone (UK and US toll-free) and an online quotation and ordering system hosted on the Biosynth Group's e-commerce platform. Pricing is quote-based and varies by length, complexity, purity, and regulatory grade; the published minimum order value is $250, while cGMP manufacture is contracted at multi-year terms scoped to project scale and regulatory requirements. Customer segments span pharmaceutical companies (primary), biotechnology and diagnostic manufacturers, and academic and research institutions, served nationally and internationally.

In September 2023, Pepceuticals was acquired by Biosynth Group, becoming a wholly-owned subsidiary whose peptide manufacturing capability — including multi-kilogram GMP capacity — extends the parent's broader chemical and biological products portfolio. As a sub-scale private CDMO within a larger specialty chemicals platform, the unit's strategic value lies in peptide-specific technical depth and cGMP manufacturing infrastructure rather than independent market scale.
