How to Tell an Original Peptide Product from a Counterfeit

Short answer: check the code on the box with the manufacturer's own website, make sure the batch number and expiry date match on the box and the vial, look closely at the print and seals, expect the order to arrive cold, and buy from a seller who shows a real address and clear product data. A price far below the market is a warning sign.

Why this matters

Counterfeits of popular compounds are not rare. In June 2024 the World Health Organization warned about falsified semaglutide pens, sold under a well-known brand name, found in Brazil, the United Kingdom and the United States, some of it in the regulated supply chain. The U.S. FDA reports counterfeits of the same brand in the U.S. supply and warns that semaglutide and tirzepatide sold illegally online may contain the wrong ingredient, the wrong amount, or no active ingredient at all, and that some labels name pharmacies that do not exist.

The checklist

1. Use the manufacturer's own code check. Many manufacturers print a code under a silver coating on the box. Enter it only on the company's official site. For ZPHC this is validation.zphc.com, and ZPHC states that no other website is authorised to check its products. A code that was already used, or a check page on another domain, is a warning sign.
2. Match the batch number and expiry date. The batch (lot) number and the expiry date should be printed clearly and be the same on the outer box and on the vial or pen.
3. Look at the packaging. Blurred print, spelling mistakes, a different colour or font from the brand's usual box, or a broken seal are all reasons to stop and ask.
4. Expect cold delivery. Peptides are usually kept refrigerated (follow the storage line printed on the label). An order that arrives warm, without ice packs, was not handled the way it should be.
5. Check the seller. A real seller shows a company name, an address, a phone number and its own product photos with the strength written clearly, and answers your questions before you pay. Be careful with sellers who promise results.
6. Compare the price. A price far below other sellers for the same brand and strength often means the product is not what the box says.

What regulators advise

For medicines, the FDA and the WHO advise buying only from licensed pharmacies. The products in our store are listed for laboratory research use only; they are not sold as medicines and we give no dosing or usage instructions.

How we handle it at Egypt Peptides

Each product page shows the brand, strength and a photo of the label, and, where the manufacturer offers it, a link to its own code check. We deliver orders ourselves with ice packs so they arrive cold. If anything about a box looks wrong, send us a photo on WhatsApp before you open it. See also our guide to original peptides.
