99% purity - 100% money back guarantee- Free shipping worldwide

Shipping Protection covers your order against the two things most likely to keep it from reaching you: customs seizures and carrier mishaps.

What's covered:

  • Customs seizure — if your package is held or confiscated by customs, we'll send a free replacement.
  • Lost in transit — if the carrier's tracking shows your package as lost and it never arrives, we'll send a free replacement.
  • Damaged in transit — if your package arrives visibly damaged, we'll send a free replacement.

How it works: if any of the above happens, contact our support team with your order number (and documentation of the seizure or damage, where relevant). We'll ship a new order at no extra cost — no refund request, no hassle.

Not covered: packages confirmed as delivered by the carrier, orders placed with an incorrect shipping address, and theft after delivery.

Our Purity Promise

Every batch of Peptonia peptides is third-party lab tested before it ever reaches you. We stand behind that testing completely — so much so that we back it with a full money-back guarantee.

If you send your product for independent lab testing and it does not verify at 99%+ purity, we will refund your order in full, and we'll also cover the cost of your lab test.

That's how confident we are in what we sell. No hoops, no fine print — just clean, verified peptides, guaranteed.
