Cold Chain & Shipping
Q01 How are peptides shipped to maintain stability?
A01 All peptides are shipped as lyophilized (freeze‑dried) powder, which is stable at ambient temperatures for short periods. For international orders, we use cold‑pack insulated packaging to maintain temperatures below 8°C throughout transit. For long‑distance shipments, dry ice may be used upon request.
Q02 How long can peptides remain stable during shipping?
A02 Lyophilized peptides can typically withstand ambient temperatures for 7‑14 days without significant degradation, depending on the specific peptide. Our packaging is designed to accommodate standard international shipping times. Upon receipt, store immediately at −20°C.
Q03 What if my order arrives warm or partially thawed?
A03 Lyophilized peptides that have been exposed to brief temperature excursions during shipping are generally still viable. Contact us immediately with photos of the packaging. We will assess on a case‑by‑case basis and reship if product integrity is compromised.
Q04 Do you offer tracked shipping?
A04 Yes. All orders are shipped with full tracking. You will receive a tracking number within 48 hours of dispatch. We use DHL, FedEx, and regional courier partners depending on the destination country.
Reconstitution
Q01 How do I reconstitute a lyophilized peptide?
A01 Add bacteriostatic water (preferred) or sterile water to the vial slowly, directing the liquid to the side of the glass — do not inject directly onto the lyophilized powder. Gently swirl to dissolve; do not shake vigorously. Allow 5‑10 minutes for complete dissolution.
Q02 What solvent should I use for reconstitution?
A02 Most peptides reconstitute well in bacteriostatic water (0.9% benzyl alcohol in sterile water). For poorly soluble peptides, a small amount of acetic acid (10‑30%) or DMSO can be used to aid dissolution before diluting with water. Each product CoA includes specific reconstitution guidance.
Q03 How should I store a reconstituted peptide?
A03 Reconstituted peptides should be stored at 2‑8°C (refrigerator) for up to 28 days, or aliquoted and stored at −20°C for longer‑term use. Avoid repeated freeze‑thaw cycles as this degrades peptide integrity.
Q04 What concentration should I target for reconstitution?
A04 Common concentrations for research use are 1‑2 mg/mL. Add the appropriate volume of solvent to achieve your desired working concentration. Refer to the Certificate of Analysis for the net weight of each vial.
Customs & Import
Q01 Will my order clear customs?
A01 Research peptides are legal to import in most countries for scientific purposes. We use discrete, professional packaging and accurate customs documentation. Clearance rates are high, but we cannot guarantee customs outcomes as policies vary by country.
Q02 What happens if my package is seized by customs?
A02 In the rare event of customs seizure, contact us with documentation and we will evaluate a reship on a case‑by‑case basis. We take no responsibility for seizure due to local regulations, but we will work with you to find a solution.
Q03 Do I need to pay import duties?
A03 Import duties depend on your country's regulations and the declared value of the shipment. Buyers are responsible for any applicable import duties or VAT. Contact us before ordering if you have specific concerns about your country's customs regulations.
Q04 Can you mark packages as 'gift' or undervalue them?
A04 No. We declare accurate contents and values on all customs documentation. Misdeclaration is illegal and compromises the legitimacy of your research supply chain. We ship with professional documentation that reflects the scientific nature of the contents.
Orders & Payment
Q01 How do I place an order?
A01 Contact us via WhatsApp or Telegram to discuss your requirements. Our team will provide pricing, availability, and payment instructions. We process orders within 24 hours of payment confirmation.
Q02 What payment methods do you accept?
A02 We accept cryptocurrency (USDT, BTC, ETH), bank transfer (for verified research institutions), and other payment methods discussed on inquiry. Contact us for the current list of accepted payment options.
Q03 Do you offer bulk or wholesale pricing?
A03 Yes. We support both retail small‑volume orders and tiered bulk‑order discounts. Volume discounts are available starting from 10g quantities. Contact our team to discuss pricing and custom synthesis requirements.
