TopPep Research Materials supplies catalogue reference materials and custom-synthesised peptides to research institutions, analytical laboratories, contract research organisations and registered commercial buyers.
Being explicit about the boundary is what makes the supply position defensible for a buyer's own compliance file.
Supply catalogue and custom-synthesised peptides for laboratory research and further manufacturing use; issue a Certificate of Analysis and analytical records with every batch; provide quotations and documentation in procurement-ready format; advise on specification, handling, storage and analytical matters.
Supply material for human or veterinary use; provide dosage, administration, stacking or cycle advice; make claims of therapeutic benefit; supply to buyers seeking consumer or personal use; publish or resell customer sequences.
The supply model is built around four functions that buyers verify separately during qualification.
Solid-phase and flow-assisted assembly with purification to the agreed purity target, monitored against the specification fixed at quotation stage.
Identity by mass spectrometry and purity by reverse-phase HPLC, with the method, column and gradient recorded on the release documents.
Certificate, chromatogram, spectrum and batch traceability record assembled and checked against the order before packing.
Condition-appropriate packaging, buyer-specified labelling and international shipping documentation, with the regime recorded on the dispatch note.
