Frequently Asked Questions
Peptides are short chains of amino acids joined by peptide bonds. They are smaller than proteins and are widely studied because their sequence and structure influence how they interact in biological systems.
Lyophilized means freeze-dried. Water is removed after the material is frozen and placed under vacuum, producing a dry powder that is more stable during storage.
Reconstitution means adding the specified compatible liquid to a lyophilized powder to prepare a solution at a chosen concentration. Peptique’s reconstitution calculator converts vial amount and water volume into concentration and syringe units.
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. Peptique includes one complimentary 3 mL vial with each peptide order.
HPLC separates the components of a sample and estimates relative purity from the detected peaks. ≥99% means the main peptide peak accounts for at least 99% of the integrated signal under the reported method. Identity and measured quantity should be read alongside purity.
Janoshik is an independent chemical-analysis laboratory regarded as the gold standard for testing peptide identity, measured quantity and purity. When a report is available, open it from the product page and use its verification link or QR code to confirm it directly with Janoshik.
Follow the storage instructions shown on the relevant product page. Before reconstitution, keep the vial sealed, dry and protected from light. After reconstitution, follow the listed refrigeration range and use-by period.
Peptique delivers free across the UAE. Dubai orders placed before 6 PM usually arrive the same day, typically within four hours. Other Emirates receive next-business-day delivery when ordered before 2 PM, or delivery within one to two business days when ordered later.
