Next-day where possible

Most EU orders dispatch within 24 hours. Expedited shipping pushes that to 1-2 day delivery for most addresses across Europe.

Real documentation

Lot-specific CoAs, mass spec traces, and HPLC chromatograms — published and searchable by batch ID, not buried in support tickets.

Researcher community

Optional access to peer protocols, study summaries, and discussion threads with other researchers running comparable work.

5 Quality Checks · 100% EU Verified

The work behind every vial.

Five rounds of testing before a product earns the PX1 label. The same standard applied to your first order and your fiftieth.

The PX1 Spec

One standard. No batch exceptions.

Every lot enters our analytical workflow before it ships. If a single check fails, the whole batch is held until the cause is identified — or destroyed. Your CoA isn't a marketing artifact; it's the record of work we already did.

Verified Potency

Each vial is tested to confirm it contains exactly what the label states, down to the microgram.

Why it mattersNo guessing. The dose printed matches the dose delivered, every order.
Mass Spectrometry

99%+ Purity

Identity and purity confirmed against the target structure. Synthesis byproducts and degradation products screened out.

Why it mattersHigher purity translates to cleaner, more reproducible results.
pH & Stability

Long-Term Stability

Formulation and pH ranges validated so the lyophilized product stays intact across its shelf life.

Why it mattersThe vial you store today behaves the same when you reconstitute it next quarter.
Sterility & LAL

Contaminant-Free

Third-party sterility and endotoxin testing screens for bacteria, fungi, and bacterial toxins.

Why it mattersContamination ruins data. We remove that variable before the vial ships.
QC Verification

Batch Consistency

Precision weighing, sealing, and lot tracking enforce the same quality bar from lot to lot.

Why it mattersComparable inputs are the only way to run comparable studies.
Featured

The compound is only half the story. The paperwork is the other.

Every PX1 vial ships with the chromatogram, mass spec result, and lot ID printed on its own Certificate of Analysis. Nothing to take on faith — verify the math, every time.

FAQ

Common questions.

What purity level are PX1 peptides and how is it verified?

Every PX1 batch is guaranteed at 99%+ identity purity. Each lot is independently tested at accredited European labs using HPLC for purity quantification and mass spectrometry for identity confirmation. A Certificate of Analysis is included with every order showing the exact figures and the lot-specific chromatogram.

What's on a Certificate of Analysis and how do I read it?

The CoA is a signed lab document tied to your specific lot. It includes purity percentage (target 99%+), identity confirmation via mass spec, physical appearance, and endotoxin levels (target below 1 EU/mg). The lot number on your vial matches the lot ID on the document, so you can verify what you received against what was tested.

How should I store the lyophilized product?

Sealed lyophilized vials are stable at room temperature for short-term storage (under 3 months) in a cool, dry, dark place. For longer storage, refrigerate at 2-8°C or freeze at -20°C. Avoid repeat freeze-thaw cycles. Stored correctly, lyophilized peptides typically remain stable for 2+ years.

How fast does PX1 ship?

Orders placed before 2pm CET typically dispatch the same business day; otherwise the next. Standard EU delivery runs 3-5 business days from fulfillment, expedited 1-2. Every shipment includes free shipment protection — if it arrives damaged or doesn't arrive at all, we replace it.

Do you ship internationally?

PX1 Labs ships across all EU member states. Availability outside the EU depends on local customs regulations for research materials; reach out to support with your destination country and we'll confirm what we can do.

What is PX1 Labs and why should I trust it?

PX1 Labs is a US-based research peptide supplier focused on documentation and consistency. Our products are manufactured in-house and independently verified at accredited European labs. Every order ships with a lot-specific CoA, every claim we make is reflected in published test data, and our quality procedures are documented and reviewable.

Are PX1 Labs peptides for human use?

No. All PX1 Labs products are sold strictly for laboratory research and educational purposes. They are not approved for human consumption, veterinary use, or any therapeutic application. Placing an order is a confirmation that you are a qualified researcher and will handle materials in accordance with applicable laws and standards.

What's your return policy?

Every order is covered by free shipment protection. If a vial arrives damaged or a package is lost or stolen in transit, send us photos and tracking details within 48 hours of the delivery date and we'll send a one-time replacement. Reconstituted product is not eligible for return.

Which payment methods can I use?

Checkout runs through our Telegram shop, where you can pay by card or cryptocurrency. Payments are processed over a secure connection and confirmed instantly — no account or subscription required.

Will I get an order confirmation?

Yes. As soon as your order is placed you'll receive a confirmation in Telegram with your order summary and next steps. If you don't see it within a few minutes, message us and we'll resend it.

How is my order packaged?

Discreetly. Vials ship in plain, neutral packaging with no product names, compound names, or PX1 branding visible on the outside. Inside, each vial is protected so it arrives in perfect condition.

How much is shipping, and is it ever free?

Shipping is free across the EU on every order — no minimum. Every shipment also includes free shipment protection at no extra cost: if it arrives damaged or doesn't arrive, we replace it.

Will I get a tracking link?

Yes. Once your order dispatches you'll receive a track & trace link by message so you can follow your package in real time across the EU.

How do I reach support?

The fastest channel is Telegram — message us or the @px1labs_bot shop and you'll usually hear back within a few hours. You can also ask Mara, our on-site assistant, any product or order question directly here on the site, any time.
