No. Symax Peptides is a company and brand name. It is distinct from, and independent of, the peptide Semax. Symax Peptides is a dedicated supplier of research compounds for in vitro laboratory research; Semax is a synthetic heptapeptide studied in neuropeptide research. The two names are unrelated, although Semax is available at Symax Peptides as one of the compounds in our catalog.

Store lyophilized material at -20°C, dry and protected from light. Once dissolved for an assay, keep stock solutions at 2-8°C for short-term use or as frozen aliquots at -20°C or below, and avoid repeated freeze-thaw cycles.

All compounds are supplied as lyophilized (freeze-dried) powder in sealed, sterile glass vials, labelled with the batch number that their Certificate of Analysis refers to. The solid form gives the best stability and shelf life; dissolve it in the solvent your protocol calls for before use.

Use the solvent and concentration your protocol specifies. Let the vial reach room temperature before opening, add the solvent slowly along the inner wall and swirl gently rather than shaking until the solid has dissolved, then divide the stock solution into single-use aliquots. Handle all material according to good laboratory practice.

Lyophilized material stored at -20°C typically remains stable for 24 months or more from the date of manufacture. Solutions are less stable: use them within 14 days at 2-8°C or store them as frozen aliquots. Check the label for the batch expiry date.

Due to the nature of our products, we are unable to accept returns on opened items. However, if your order arrives damaged, contains incorrect items, or there is a quality concern, please contact us immediately and we will resolve the issue promptly.

Refunds are reviewed on a case-by-case basis. To request a refund, contact our support team with your order number, a description of the issue, and any relevant photos. Our team will respond within 1-2 business days with a resolution.

We can only reship your package if it is returned to sender. We recommend contacting your local post office to request a reroute, or setting up mail forwarding for the address entered at checkout. Always double-check your shipping address before confirming your order.
