Stability & Packaging Protocols

A common concern in peptide research is environmental degradation during transit. Polaris Peptides utilizes industry-leading protective measures:

  1. Lyophilized Stability: Our peptides are shipped in a freeze-dried (lyophilized) state. In this form, the “peptide cake” is highly stable at ambient temperatures for up to 4 weeks, ensuring zero loss of potency during standard shipping durations.

  2. Vacuum-Sealed Vials: Every vial is capped with medical-grade stoppers and vacuum-sealed to prevent oxidation and moisture ingress.

  3. Discreet & Secure Packaging: We utilize plain, durable, and unbranded over-packaging. This ensures both the privacy of your research and the physical security of the glass vials during handling.

Tracking & Delivery Transparency

We believe in full visibility from our lab to yours.

  • Automated Tracking: As soon as your shipping label is generated, a Tracking Number is automatically sent to the email address used at checkout.

  • Delivery Confirmation: For high-value or bulk institutional orders, we require a signature upon delivery to ensure the chain of custody is maintained.

  • Shipping Insurance: Every Polaris Peptides order is backed by our “Arrival Guarantee.” If your package is lost in transit or arrives with compromised packaging, we provide immediate priority replacement.

International Research Shipments

We support the global scientific community. Please note that international transit times can vary (7–14 days) depending on local customs protocols.

  • Compliance: It is the researcher’s responsibility to ensure compliance with local import regulations for in-vitro research chemicals.

  • Documentation: All international orders include the necessary commercial invoices and “Research Use Only” declarations to facilitate smooth customs clearance.
