All our peptides are manufactured to 99%+ purity standards. Each batch undergoes rigorous third-party HPLC and Mass Spectrometry testing. Certificates of Analysis (CoA) are available for every product on the product page.

Yes, every batch is tested by independent, accredited laboratories using HPLC for purity verification and Mass Spectrometry for identity confirmation. Test results are published on each product page as Certificates of Analysis (CoA).

CoAs are available on each product page. Simply click the "Certificate of Analysis" link to view or download the current batch's test results. You can also request specific CoAs by emailing support@halolaboratories.com with your order number.

Our peptides are synthesized in USA-based, FDA-registered facilities following strict cGMP guidelines. We maintain complete supply chain transparency and never source from overseas manufacturers.

Lyophilized (powder) peptides should be stored at -20 degrees C for long-term storage or 2-8 degrees C (refrigerator) for short-term. Once reconstituted, store at 2-8 degrees C and use within 4-6 weeks. Always protect from light and avoid repeated freeze-thaw cycles.

Lyophilized peptides have a shelf life of 2+ years when stored properly at -20 degrees C. Reconstituted peptides should be used within 4-6 weeks when refrigerated. Each product includes a lot-specific expiration date.

Use bacteriostatic water (BAC water) for reconstitution. Slowly inject the water down the side of the vial, allowing it to gently dissolve the peptide. Never shake vigorously. Detailed instructions are available on each product page and included with your order.

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. It prevents bacterial growth and allows reconstituted peptides to remain stable for 4-6 weeks when refrigerated. We offer pharmaceutical-grade BAC water in our store.

The amount varies by peptide and desired concentration. We provide reconstitution calculators and guides on each product page. A common approach is using 1-2mL of BAC water per vial, but always check the specific product recommendations.
