All peptides ship in insulated packaging with cushioned vial protection. Lyophilized peptides are shelf-stable and require no cold chain in transit. Discreet exterior packaging — no product branding on the outside.

All peptides are manufactured to 99%+ purity. Every batch undergoes independent HPLC purity analysis and mass spectrometry identity confirmation by accredited US laboratories. Certificates of Analysis are available for every product.

Lyophilized peptides: −20°C for long-term, 2–8°C for short-term under 3 months. Once reconstituted with bacteriostatic water: store at 2–8°C and use within 4–6 weeks. Avoid repeated freeze-thaw cycles and protect from light.

Lyophilized peptides have a 2+ year shelf life when stored properly at −20°C. Reconstituted peptides: use within 4–6 weeks when refrigerated. Each vial includes a lot-specific expiration date.

Use bacteriostatic water (BAC water). Inject the water slowly down the side of the vial — never directly onto the peptide cake. Allow it to dissolve gently. Swirl gently if needed. Never shake or vortex.

Pharmaceutical-grade sterile water containing 0.9% benzyl alcohol as a preservative. It prevents bacterial growth and keeps reconstituted peptides stable for 4–6 weeks when refrigerated. We sell pharmaceutical-grade BAC water in our accessories section.

Depends on your desired concentration. A common starting point is 1–2 mL per vial. Each product page includes specific reconstitution guidance. Contact our support team if you need help calculating your concentration.

Yes. Every batch is tested by independent, accredited US laboratories using HPLC for purity and mass spectrometry for identity. All results are published as Certificates of Analysis accessible via your batch reference number at verify.orvantalabs.com.
