CertaPeptides Review: Janoshik Reports, Vial Code Lookup and EU 14-Day Returns

CertaPeptides is the store of CERTALAB S.R.L., a limited liability company registered in Bucharest, Romania, in 2026. It sells freeze-dried research peptides and a small range of lab consumables to buyers in 26 EU member states, Switzerland and the UK.

We looked at the homepage, the shop, the quality and COA pages, the About page and the shipping and returns page. The store publishes more company detail than most, and its lab reports name the testing lab and link to that lab's verification page. The main limits are that reports cover selected lots only and do not show identity data.

Who CertaPeptides is and what the catalog covers

The About page lists the company's trade register number, tax ID and EU VAT number, and the site lists a street address in Sector 1 of Bucharest, a phone number and a support email. The site describes its audience as researchers and laboratories doing in-vitro work.

The shop lists 36 products in eleven categories. The range covers single peptides such as BPC-157, GHK-Cu, Epitalon, Thymalin and LL-37, a GLP-1 class group, a few blends, and consumables including bacteriostatic water, acetic acid water and empty storage vials. Prices are in euros, starting at €5.99 for reagents and reaching about €77 for the starting size of the most expensive listing, with larger sizes priced higher.

Testing and certificates: Janoshik reports for selected lots

All independent reports in the COA vault are attributed to Janoshik Analytical. The site cites 56 published reports covering 29 products, with test dates from March to October 2026. Each card shows a report code and links to Janoshik's own verification page, so a buyer can confirm the report with the lab.

What a report shows varies:

• Most cards list a purity percentage and measured content, in milligrams and as a share of the label amount. The 50 mg Epitalon card, for example, shows about 99.5% purity and 49.02 mg measured.
• Some cards show measured content only, with no purity figure.
• A few products have endotoxin results listed as measured values.

Three limits matter. First, the vault states that a report covers one tested size and does not mean every size or shipped lot was tested. Second, seven product lines rely on supplier specifications rather than an independent report. Third, the reports do not name a method or show an observed molecular mass, so identity cannot be checked from the site.

Each vial label carries a code that buyers can scan or enter on a lookup page to see published information and any withdrawal notice. The company says it does no testing in-house. It also says it will investigate, and replace at no cost, any unit from a published lot that a Janoshik test shows below 98% purity.

Labeling and purchase checks

An entry screen asks visitors to tick a box confirming they are 18 or older and using the site for research, and buyers confirm research use again when ordering. Nearly every product page carries a research-only and not-for-human-consumption notice, and no usage directions appear.

Some category names and product descriptions, however, frame compounds by the effects studied in published research and cite preclinical papers. The site adds that these are not medical claims, but the framing falls short of strict research-use labeling.

Ordering, payment and shipping across Europe

Checkout accepts SEPA transfer, Paysera, Visa, Apple Pay and Google Pay. The site states that Mastercard is not accepted. A site banner offers free shipping on orders over €200, a threshold the shipping page itself does not repeat.

Orders leave Romania within 1 to 2 business days, and carriers depend on the destination:

• Sameday within Romania, from €4.99, in 1 to 2 days
• GLS across the core EU road network, standard delivery in 3 to 7 days
• TCE Worldwide for standard delivery to the remaining EU countries, Switzerland and the UK
• DHL Express for faster cross-border delivery

Packaging is described as discreet and temperature-stable, with no mention of cold packs. Buyers outside the EU pay any import duties, import VAT and clearance fees.

Refunds, reships and support

The returns terms follow the EU 14-day withdrawal right. Buyers email support within 14 days of delivery, receive a return authorization within one business day, and send back unopened items in their original sealed packaging. Return postage is the buyer's cost unless the company made an error, and refunds go to the original payment method within 14 days of the withdrawal notice.

Transit damage must be reported within 48 hours of delivery with photos of the box, inner packing and vial labels. Confirmed damage is replaced by the original shipping method. Opened items and items stored outside recommended conditions cannot be returned, and parcels seized by customs are not replaced. Support is available by email and phone.

Verdict: strong company details, selective lot testing

CertaPeptides suits EU, Swiss and UK labs that value a registered company, a named testing lab and clear withdrawal terms. It is a weaker fit for labs that need identity data or a report for the exact lot they receive.

Before ordering:

• Check whether your product and size have a Janoshik report or rely on supplier specifications only.
• Enter the vial code on the lookup page after delivery and compare it with the published report.
• Ask support whether mass spec identity results exist for the lot you will receive.
