TCS NEXUS S.L. supplies cosmetic-grade peptides and bioactive ingredients to formulators, contract manufacturers, and brands across Europe. Every peptide in our catalogue complies with EU Cosmetics Regulation (EC) No 1223/2009, produced with HPLC-verified purity of ≥99%. We stock in Valencia, Spain, so EU delivery takes 5-7 working days instead of the 4-6 weeks typical for direct-from-Asia sourcing.
Our range covers the major peptide categories used in modern skincare: signal peptides (GHK-Cu, Acetyl Decapeptide-3) for collagen stimulation, neurotransmitter-inhibiting peptides (Acetyl Hexapeptide-8, Dipeptide Diaminobutyroyl Benzylamide Diacetate) for expression line reduction, carrier peptides for mineral delivery, and enzyme-inhibitor peptides for targeted skin conditioning. We also supply non-peptide actives that formulators frequently pair with peptides: Ectoin for barrier protection, Ergothioneine for antioxidant defense, Glutathione for brightening, and Carnosine for anti-glycation.
