Institutional Grade Assurance
Quality Guarantee &
Stability Policy
Purity Specification
We guarantee that every research compound synthesized at our facility meets or exceeds the HPLC-verified 99% purity threshold. If a batch fails to meet the molecular mass requirements specified in its COA, we provide immediate replacement.
Stability Warranty
Our peptides are stabilized via proprietary lyophilization. We warrant that the molecular integrity remains 100% intact during transit when stored in our vacuum-sealed, pharmaceutical-grade glass vials.
The "Hub" Integrity Standard
At Peptide Sciences Hub, our warranty is based on analytical data. Unlike consumer goods, the "warranty" on a research chemical is a guarantee of its chemical sequence and purity.
- Arrival Condition: We warrant that all vials arrive without micro-fractures and with the vacuum seal fully engaged. Any compromised seals must be reported within 24 hours of delivery.
- Sequence Accuracy: Every compound is warranted to match the specific molecular weight verified by our Mass Spectrometry (MS) documentation.
- Stability Window: We guarantee the bio-activity of lyophilized peptides for up to 24 months if stored according to our cold-chain guidelines (-20°C).
Claims & Verification Process
To ensure institutional accountability, all quality claims must follow our scientific verification protocol:
- Submit your Batch Number and Order ID to our technical support team.
- For claims regarding purity, we require a scan of the independent laboratory analysis (HPLC) showing the discrepancy.
- Upon verification of a synthesis error, a replacement batch is dispatched within 24 hours via expedited cold-chain logistics at no additional cost.
