Frequently asked questions
Quick answers to the things people ask most. If your question isn’t here, the contact form gets routed to a real human.
Shipping & delivery
How long does EU delivery take?+
Most EU orders arrive within 3–5 business days. We dispatch within 1–2 business days of payment confirmation, with full tracking from the carrier.
Do you ship outside the EU?+
We ship to most countries in Europe and select destinations beyond. If you do not see your country at checkout, contact support and we’ll quote freight directly.
Will my order get through customs?+
Research peptides ship under the appropriate research-use classification. We package discreetly and include the documentation expected for your destination. We cannot guarantee customs decisions in any specific country — local laws vary.
How are vials packaged?+
Lyophilized vials ship in plain insulated boxes with cold-pack inserts where the compound’s stability profile requires it. The label is neutral; nothing on the outside indicates the contents.
Do you offer free shipping?+
Yes — free standard EU shipping on orders over €100, and on bulk packs of 25 vials or more.
Lab testing & COAs
Where can I find the Certificate of Analysis for my batch?+
The most recent batch’s COA is linked from each product page. To request the specific COA matching your shipment, use the lookup form on the Certificates of Analysis page with your batch or order number.
What testing is performed on each batch?+
Independent third-party HPLC purity analysis on every batch, with mass spec confirmation and endotoxin screening on applicable compounds. We publish the raw results, not just a pass/fail summary.
What is your purity standard?+
Our minimum release threshold is 99% purity by HPLC. Batches below the threshold are not stocked.
Storage & handling
How should I store my vials?+
Lyophilized product: −20°C, dry, light-protected. After reconstitution: 2–8°C, used within the timeframe noted on that compound’s COA. Specific storage notes ship inside every box.
What should I reconstitute with?+
Bacteriostatic water is the standard solvent for most lyophilized peptides. We stock it under Lab Supplies; you can also source it locally.
Orders, payments & returns
Which payment methods do you accept?+
All major cards (Visa, Mastercard, Amex), bank transfer for EU orders, and select alternative methods at checkout. All payments are processed via PCI-compliant providers.
Can I return an order?+
Sealed, unopened items are returnable within 28 days for a full refund. Opened or temperature-sensitive items are non-returnable for safety reasons. Email support before shipping anything back so we can issue an RMA.
What if my package arrives damaged?+
Photograph the outer box and the contents and email support within 48 hours of delivery. Damaged-on-arrival shipments are replaced no questions asked.
Account & wholesale
Do I need an account to order?+
No — guest checkout is supported. An account speeds up reorders and gives you order history, batch lookups, and saved addresses.
Do you offer wholesale or white-label?+
Yes. See the Wholesale page for tier pricing, white-label services, and the partner inquiry form.
