Where to Buy Research Peptides
The question „where to buy research peptides“ is rarely about who sells them — there is no shortage of sellers. It is about how to tell that what arrives in the envelope is what the label says. This page is the procedure you can run against any supplier, including us.
Six things to check before a first order
- A certificate of analysis for your batch, not a sample one. The difference matters. A sample certificate proves a lab once tested something. A certificate tied to the batch number printed on your vial says something about the contents of your vial.
- The name of the laboratory. „Lab tested“ without naming the lab is a marketing line, not a data point. If the manufacturer issued the certificate itself, that is not independent testing — it is the manufacturer’s own claim in a nicer format.
- Two methods, not one. HPLC speaks to purity (what share of the total peak area the main peak occupies). Mass spectrometry speaks to identity (whether the compound has the expected molecular weight). HPLC alone cannot separate the right compound from a wrong one with a similar retention time.
- Who the seller is. Look for a company name, a registration number and an address — not just an email and a contact form. A seller who does not identify itself leaves you with nobody to raise a complaint against.
- Where the goods physically ship from. „EU delivery“ is not the same as „EU stock“. A parcel from Asia clears customs: duty and import VAT are added to the price, weeks to the timeline, and whether it arrives at all is an open question.
- What happens when something is wrong. Check that the shop publishes written return conditions with a stated window. „Money back“ with no conditions attached is not a commitment.
The certificate of analysis: what to look for
A certificate is not a quality seal, it is a measurement report. When you receive one, check four things:
- Batch number — it must match the number on the vial label. If it does not, the certificate describes different goods.
- Date of analysis — it should fall in the period the batch was produced, not years earlier.
- Measured purity as a figure — „>99 %“ in the website copy and „98.4 %“ in the report is a gap worth noticing.
- Molecular weight from mass spectrometry — it should match the theoretical value for that compound to within a fraction of a dalton.
The full walkthrough, including how to confirm a report is genuine with the laboratory itself, is on the batch verification page.
Where orders ship from, and how long they take
We dispatch from stock held in Slovakia, inside the EU. Parcels to EU addresses therefore clear no customs border — no duty, no import VAT, no hold at the frontier. Orders placed before 16:00 CET go out the same working day.
- Packeta pickup point: €3.90
- Courier to your address: €7.90
- Free shipping on orders over €100
- Transit: typically 1 – 3 working days within central Europe
One practical note: put the house number at the end of the street line („Main Street 12“). With the number in front, the carrier cannot generate a shipping label and the parcel is delayed.
Payment and paperwork
The shop is operated by Vexio j. s. a., company ID 54214530, registered in Banská Bystrica, Slovakia. Every order comes with an invoice from a registered company — not a payment confirmation from an unnamed party. The company is not registered for VAT, so no VAT appears on the invoice and the price you see is the price you pay.
You can pay by SEPA bank transfer, cryptocurrency or cash on delivery. Transfer and crypto are discounted, cash on delivery carries a fee — the exact terms are shown at checkout before you confirm.
Legal framing: what these compounds are and are not
These are chemicals supplied for in-vitro laboratory research. They are not medicines, food supplements, cosmetics or medical devices. They have not been through any approval process for human use and are not intended for administration to humans or animals. They are sold strictly for research and analytical purposes.
Responsibility for what a compound is used for, and whether that purpose is permitted in a given country, rests with the buyer. If you need a legal view on your specific situation, seek qualified advice — this page is not a substitute for it.
Quick checklist
| What to check | Good answer | Warning sign |
|---|---|---|
| Certificate | Tied to the batch number, sent within 24 h on request | Sample certificate only, or none |
| Laboratory | Named, independent of the manufacturer | „Lab tested“ with no name |
| Methods | HPLC (purity) + MS (identity) | A percentage with no report behind it |
| Seller | Company name, registration number, address | Email and a contact form only |
| Stock | Held in the EU, no customs clearance | Dispatched from Asia |
| Returns | Written conditions with a stated window | Nothing, or an empty page |
Common questions
Can I see the certificate before ordering?
Yes. Tell us which compound you are interested in and we will send the certificate for the current batch — so the decision rests on data rather than on a promise.
Why is the same compound much cheaper elsewhere?
Price reflects purity, testing every batch, and holding stock inside the EU. A price without testing and without EU stock is necessarily lower — and that is precisely what is missing from it.
What is the difference between a pickup point and a courier?
Only the delivery method and the price. A Packeta pickup point is €3.90, a courier to your address €7.90. Both are free over €100.
How should the compounds be stored on arrival?
Lyophilised powder is stable at room temperature and needs no cold-chain transport. Once reconstituted, it belongs in the refrigerator.
