Research Return Policy
All analytical peptide orders may be cancelled prior to synthesis or cold-chain dispatch.
Return requests must be logged within 14 days of receipt of lyophilized peptide vials, subject to laboratory temperature monitoring and integrity verification standards.
To submit a return inquiry, please provide your analytical batch number and formal authorization statement.
Direct notices to: qa@purepeptides.com
Refunds are processed within 14 days following quality-control spectroscopic validation of returned vials. Approved credits are issued back to the institutional payment method or original purchasing account.
Return Eligibility
To qualify for authorized return, peptide vials must satisfy the following:
Vials remain factory-sealed under vacuum
Storage integrity verified
Non-returnable peptide materials:
Custom peptide sequences synthesized specifically to institutional order specifications.
Reconstituted peptide solutions or vials with breached crimp seals and septa.
Materials compromised by non-compliant temperature handling or cold-chain interruptions.
Peptide standards cross-contaminated or stored past specified chemical stability dates.
We reserve full technical discretion to decline items compromised by improper environmental exposure or handling.
Sample Return
Institutions assume shipping transit liability and must preserve cold-chain standards to our analytical laboratory:
QC Research Lab 4B
SynthLab assumes no liability for vials lost or degraded during transit. Cold-pack insulated shipping with continuous tracking is mandatory for return acceptance and subsequent laboratory verification.
Grants
Orders billed to university departmental grants or institutional research budgets are credited directly back to the active research grant ledger or replaced with equivalent analytical-grade batches upon confirmation.
If procurement was processed via a third-party laboratory supplier or sponsor, reimbursement credits will route strictly through the designated purchasing entity.
