These materials have legitimate applications within appropriate settings, and responsibility for their correct use rests with the purchaser. Nevertheless, UK Peptides also acknowledged wider concerns about standards across the sector, stating that greater clarity and consistency across the sector would be beneficial in supporting both public safety and industry accountability, particularly where it helps distinguish responsible suppliers from those operating without appropriate standards. UK Peptides emphasised that they place a strong emphasis on quality, consistency and traceability, [and] maintaining these standards is resource-intensive and represents a key distinction between established operators and lower-cost entrants.
