Research-focused product range

Our product range is built to support diverse experimental needs. Peptide vials are available in multiple sizes and concentrations to fit assay development, in vitro studies, and analytical workflows. For studies of delivery routes or formulation stability, we offer premixed pens and nasal sprays in standard research volumes. Topical peptides such as GHK-Cu and Matrixyl are supplied for investigational work in skin biology and wound-healing research. In addition, blended products and stacks enable researchers to investigate synergistic or comparative effects under controlled laboratory conditions.

Quality assurance and documentation

Quality and traceability are central to research reproducibility. Most of our peptides are supplied with a guaranteed minimum purity of 99%, while more complex sequences are offered at a minimum of 98% purity. Batch testing and Certificates of Analysis (COAs) are available to verified research organizations on request; these documents typically include LC-MS/GC-MS and other analytical results that support experimental planning and reporting. If you require specific documentation for institutional compliance or publication, request the COA prior to purchase.

Packaging, quantities and pricing

Products are offered in flexible quantities and pack formats to suit different project scales. Twin and quad pack options enable cost-efficient bulk purchasing for long-term studies, while single vials and smaller pre-mixed formats support pilot experiments and method development. Pricing varies by peptide, formulation and pack size; all options and current prices can be viewed on the product pages at our site.

Formulation types explained (for research context)

Peptide vials provide the most direct format for laboratory assays and analytical work. Pre-mixed pens and nasal sprays are supplied as ready-to-use research formulations for investigators studying stability, dosing comparators, or delivery systems under controlled conditions. Topical formulations are intended for in vitro or ex vivo skin research and formulation testing. Stacks and blends are combinations of peptides prepared to help researchers explore interactions or to create comparative study arms.
