Common questions
Before you order.
How long does delivery take?
Orders dispatch the next business day. United Kingdom 2-3 days, EU 2-4 days, rest of world 3-5 days. Free express shipping on every order. See the shipping tab above for full transit times by country.
How are the pens packaged?
In a discreet, tracked express parcel with a tamper-evident seal. The outer label is plain, with no product references. Refrigerate the pen on arrival.
How should I store the pens after delivery?
Refrigerate at 2 to 8 °C, away from direct light. Once the seal is broken, refrigerate and use within the stability window noted on the product page. Do not freeze.
Do orders include a certificate of analysis?
Yes. Every lot is independently third-party tested. An HPLC purity certificate and a separate aqueous pH certificate are published before each lot ships. Both are linked in the lab certificates tab above.
What if my package arrives damaged?
Send a photo of the box and tamper seal on WhatsApp within 24 hours of delivery. We replace any damage in transit the same business day, free of charge. No return needed.
How do payments work?
Card checkout isn't available on this site for peptides, so every order is confirmed person to person. After checkout we open a short WhatsApp chat, answer anything you want to know, and send a secure payment link where you can pay with Stripe, Apple Pay, Google Pay, PayPal, iDEAL or Klarna, depending on your country. Your order stays on hold until you confirm.
