About Peptiko — Laboratory-Grade Peptide Reagents

Our Mission

Peptiko was founded to close a specific supply gap in Eastern European peptide research. For years, qualified researchers working in Moldova, Romania, and the wider CIS region had only two practical options for sourcing peptide reagents: import from distant suppliers in North America or Western Europe, accepting multi-week transit times and steep courier fees, or rely on opaque regional intermediaries with no meaningful analytical documentation. Neither option served the needs of a rigorous laboratory programme.

We supply ≥99% HPLC-verified peptide reagents for in-vitro laboratory research. Our focus is scientific accuracy, analytical transparency, and consistent lot-to-lot quality for the institutions and independent research groups we serve. Every compound we list is sourced from a qualified synthesis partner, independently verified in a third-party analytical laboratory, and released only after the purity and identity data match specification.

Peptiko positions itself as a regional supplier operating to EU-grade analytical standards. By basing operations in Moldova and maintaining direct logistics into Romania and the EU, we compress delivery times from weeks to days for most regional orders. Every compound in our catalog ships with a third-party Certificate of Analysis so research teams can verify identity and purity before any experimental work begins — no guesswork, no trust-by-default.

Our longer-term vision is to become the trusted reagent partner for Eastern European research laboratories: the supplier a principal investigator or lab manager can name without hesitation when asked where their peptide compounds come from. That reputation is earned one verified lot at a time, and we treat every shipment as an opportunity to reinforce it.

Why We Built Peptiko

The state of peptide research supply in Eastern Europe in 2026 is uneven. Academic laboratories in Chișinău, Bucharest, Iași, Cluj, Minsk, and Kyiv routinely run into the same set of obstacles when sourcing reagents: long customs holds on shipments from overseas, suppliers that publish in-house purity claims without independent verification, inconsistent lot documentation, and pricing that reflects intercontinental freight rather than the actual cost of the compound. Researchers adapt, but the friction is real, and it slows down work that should not be slowed down.

We have spoken with enough lab managers and independent researchers to recognise the pattern. The most common pain points are predictable: a shipment sits at customs for three weeks because the HS code on the commercial invoice is wrong; a Certificate of Analysis arrives as a scanned PDF with no third-party signature; a lot that was advertised as 99% pure produces inconsistent results, and no analytical recourse is available. Each of these issues is solvable, and each one is avoidable when the supplier takes documentation seriously.

Peptiko is structured to address each of these pain points directly. We pre-classify all shipments under the correct heterocyclic-compound HS codes so customs clearance is routine rather than exceptional. We commission third-party analytical verification for every new lot, not just a sample drawn at random. We publish lot identifiers and make the corresponding Certificate of Analysis available on request before an order is placed. And we keep our regional focus tight enough that transit times remain measured in days, not weeks.

Underlying all of this is a commitment to scientific transparency. A reagent supplier operates downstream of synthesis but upstream of every experiment the compound will be used in. That position carries responsibility: if the material is misidentified, contaminated, or degraded, every result downstream is compromised. We take that seriously, and the systems we have built are designed to make it as easy as possible for a researcher to verify what they are receiving before it ever enters a pipette.

How Every Compound Is Verified

Third-party verification matters because in-house testing alone is not enough. Independent analytical surveys conducted across the peptide reagent market in 2026 have found that a substantial share of vendors — by some estimates close to 40% — ship material that fails to meet the purity values stated on their own Certificates of Analysis. The gap is not always the result of bad faith; synthesis is difficult, storage conditions matter, and internal QC cannot always catch every deviation. But the practical consequence for a researcher is the same either way: material that does not perform as labelled wastes time, consumables, and experimental credibility.

The distinction between an in-house COA and an independent third-party COA is straightforward. An in-house COA reports the synthesiser's own analytical findings on their own lot — the party with the strongest commercial interest in the result also controls the instruments. A third-party COA is generated by an independent analytical laboratory that has no stake in the outcome, which is why it carries significantly more weight in any rigorous sourcing workflow. At Peptiko, we use third-party verification as the authoritative reference and treat the supplier's own COA as supporting documentation, not as proof on its own.

The core analytical techniques we rely on are well established. High-performance liquid chromatography (HPLC) separates a lot's components by their differential interaction with a stationary phase, producing a chromatogram whose peak areas quantify purity. Mass spectrometry (MS) ionises the sample and measures the mass-to-charge ratio of the resulting fragments, confirming that the compound present matches the expected molecular weight and structural fingerprint. Together, HPLC-MS establishes both how pure a lot is and whether it is actually the compound claimed on the label. A "good" lot produces a single dominant HPLC peak at or above the stated purity threshold with an MS signature consistent with the target compound; a "rejected" lot shows extra peaks, a wrong mass, or degradation products, and never enters our inventory.

Our four-step verification protocol is designed to eliminate the guesswork researchers face when sourcing reagents. From initial synthesis partner qualification through final cold-chain release, each lot is traceable and independently confirmed.

Where We Ship

Peptiko dispatches research reagents to laboratories across four primary regions: Moldova, Romania, the CIS (Russia, Ukraine, Belarus), and the European Union. Our regional focus is deliberate. By concentrating on territories we can reach reliably within days rather than weeks, we keep transit windows short, customs outcomes predictable, and cold-chain integrity intact from dispatch to delivery. Expanding further would mean longer lead times and more variables outside our control, and we would rather serve a defined region well than serve a wider one inconsistently.

Each region has its own customs and logistics profile, and we handle the paperwork accordingly. Moldovan orders dispatch domestically with minimal friction. Romanian and EU orders move through the EU common customs area under standardised research chemical declarations, using DHL and UPS express networks. CIS shipments require more detailed commercial documentation and we prepare each consignment with the appropriate HS codes, commodity descriptions, and supporting COAs to minimise clearance delays. Every shipment is tracked end-to-end, and the reference numbers are shared with the recipient at dispatch.

Language and support coverage matches the regions we serve. Correspondence and documentation are available in English, Russian, and Romanian, and our catalog is localised across all three. A research group in Cluj can order in Romanian, a laboratory in Minsk can request a COA in Russian, and an EU institution can default to English — in each case the response comes from the same underlying quality and documentation system. All dispatches use tracked courier services with customs documentation aligned to research chemical HS codes.

Our Standards

The following specifications apply to every compound we list. They are not aspirational targets — they are the minimum thresholds a lot must meet before it is released for shipment. Lots that fall short are rejected.

• ≥99% HPLC-MS purity. Every lot is verified by high-performance liquid chromatography paired with mass spectrometry, with purity reported as the percentage of total integrated peak area. A value of 99% or higher means essentially all of the material in the sample is the target compound, with any remaining fraction consisting of trace synthesis byproducts below the level of analytical significance.
• Third-party Certificate of Analysis on every lot. We commission independent verification from external analytical laboratories. Janoshik Analytical in the Czech Republic is one example of the class of third-party labs whose reports we reference; the key point is that the verifying party is not the synthesiser and has no commercial interest in the result.
• Lyophilized powder format. Compounds are supplied as freeze-dried (lyophilized) powder rather than pre-reconstituted solution. Lyophilisation removes water from the sample under low temperature and low pressure, which dramatically extends shelf stability and reduces the risk of degradation during transit and storage. Reconstitution at the destination laboratory gives the research group full control over solvent choice and concentration.
• Cold chain handling. Long-term storage is at −20°C under controlled conditions. Temperature-sensitive compounds are dispatched in insulated packaging with cold packs calibrated to preserve the lyophilized state throughout transit to the destination laboratory.
• Compound traceability from synthesis to delivery. Each lot carries a unique internal identifier that links the finished inventory unit back through third-party verification, supplier master batch documentation, and the original synthesis record. If a question arises about a specific shipment, we can trace the full chain of custody.
• Compliance with the REACH research exemption. Our operations respect the research and development provisions of the EU REACH regulation, which exempts substances used in scientific research and development from certain registration requirements when supplied in controlled quantities for non-commercial research use.

Our Transparency Commitment

We publish our quality process publicly because we believe research suppliers have an obligation to communicate clearly, document rigorously, and respect the regulatory environment researchers operate within. A supplier that cannot explain how its material is verified is asking customers to take the most important claim about the product entirely on trust, and trust without evidence is not a reasonable standard in a scientific context. Everything on this page — the verification protocol, the analytical techniques, the cold chain procedure, the customs classification — is published so that a qualified researcher can evaluate our process before committing to an order.

Before placing an order, customers can verify several things independently. The Certificate of Analysis for any listed compound is available on request, and the lot identifier can be cross-referenced with the third-party analytical laboratory that produced the report. Product descriptions cite published pre-clinical literature rather than marketing claims, so the scientific context of any compound can be checked against the primary sources. Shipping documentation, HS codes, and the regulatory framing of each order are stated upfront, so a lab manager or institutional purchasing office can assess the paperwork before committing.

• No misleading marketing claims. We do not make therapeutic, medical, or performance assertions about any compound. All product descriptions are drawn from published pre-clinical literature and presented as research context only.
• COA available on request before ordering. Qualified researchers can request the relevant Certificate of Analysis for any listed compound prior to placing an order, allowing lab-side verification of purity and identity.
• Research use only. Every compound is supplied strictly for in-vitro laboratory research in accordance with EU research chemical regulations. We do not ship to jurisdictions where applicable research reagent rules prohibit import.
• Transparent customs classification. All products are declared under HS codes 2933.99 / 2934.99 (heterocyclic chemical compounds) with full documentation accompanying each shipment.

Failed-lot policy. If a compound arrives with documentation that does not match the verified reference data, or if subsequent independent re-analysis by the receiving laboratory identifies a material discrepancy with the Certificate of Analysis we supplied, we replace the lot at no cost or issue a full refund at the researcher's preference. The cost of a failed sample in a research workflow is far greater than the cost of the reagent itself, and our replacement policy is structured to recognise that asymmetry.
