Lyophilized (freeze-dried) peptides should be stored at -20°C for long-term storage. Short-term storage at 4°C (refrigerator) is acceptable. Keep peptides away from light and moisture. Reconstituted peptides should be stored at 4°C and used within the timeframe specified on the COA.

Lyophilized peptides stored at -20°C typically remain stable for 2+ years. At 4°C, stability is generally 6-12 months. Reconstituted peptides have shorter stability, typically 2-4 weeks when refrigerated. Always check the expiration date on your COA.

Yes, general reconstitution guidelines are provided with each order. Typically, peptides are reconstituted with bacteriostatic water or sterile water. Specific protocols depend on your research requirements.

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth. It's preferred for reconstituting peptides that will be used over multiple days, as it helps maintain sterility and extends the solution's usability.

Generally, we don't recommend freezing reconstituted peptides as freeze-thaw cycles can cause degradation. If you must freeze, aliquot into single-use portions to avoid repeated freezing and thawing.

Lyophilized peptides are stable at room temperature for short periods during transit (typically several days). As long as the seal is intact and the peptide appears as expected (usually a white powder), it should be fine. Store properly upon receipt.

We accept returns of unopened, undamaged products within 14 days of delivery. Products must be in original packaging with seals intact. Contact us to initiate a return and receive a Return Authorization number.

Contact us immediately with photos of the damage or incorrect item. We'll arrange a replacement or full refund at no additional cost. Please keep all packaging until the issue is resolved.

Refunds are processed within 5-7 business days after we receive and inspect the returned item. Bank transfer refunds may take an additional 2-3 days to appear in your account. Bitcoin refunds are processed at the current exchange rate.

Yes, we accept exchanges for unopened products. Return the original item and place a new order, or contact us to arrange an exchange. Any price difference will be charged or refunded accordingly.

If independent testing shows our product doesn't meet stated purity specifications, we'll provide a full refund or replacement. Please provide documentation of your testing methodology and results.

Shipping costs are refunded if the return is due to our error (wrong item, damaged product, etc.). For change-of-mind returns, original shipping costs are non-refundable and return shipping is the customer's responsibility.
