Our story

A small beginning.
A clearer way forward.

Blue laboratory workspace with analytical equipment and glassware.
The research standard that shaped Adria Science.

Adria Science began with a frustration: sourcing research peptides could involve too much uncertainty. Inconsistent quality, missing documents and reports that could not be independently verified made it difficult to judge what was actually being offered.

We wanted to build the kind of supplier we would feel comfortable relying on ourselves. That meant looking at the whole process: how the peptides are made, how a batch is tested, how the results are documented and how an order is handled.

So we started small and built around those priorities. Careful sourcing, independent laboratory work, clear product information and reachable support became the foundation of Adria Science.

We have spent a long time working through the practical details, trying and refining the experience from sourcing and documentation to packing, dispatch and support. The aim has always been to make the whole journey dependable, right through to the person receiving the order.

We have grown, but the reason we started has stayed the same. Whether you are comparing products for a new project or returning to something familiar, we want your next order to feel informed, straightforward and well supported.

Manufacturing context

Quality begins
before the finished vial.

Our peptides are produced using solid-phase synthesis by a manufacturer inspected by the FDA, NMPA, EMA, TGA and MFDA, and compliant with cGMP, ISO 9001 and ISO 13485 standards.

Each batch of peptides undergoes rigorous blind and independent third-party testing across multiple laboratories. This connects the manufacturing process with analytical verification and gives our research peptide range a documented basis for review.

For us, manufacturing and testing belong in the same conversation. The production process establishes the starting point; independent analysis provides information about the batch itself. Product identity, batch numbers, analytical methods and measured results help you assess the material in front of you.

That is the approach behind our quality standard: care in production, scrutiny through testing and documentation that researchers can actually use. We bring those elements together across our range, with product-specific reports available through the Test Results Library.

Quality you can review

Look closer.
The details are there.

A Certificate of Analysis connects a named product and batch to a laboratory’s findings. Our library lets you review the available reports before ordering and return to them when you need the details.

Identity, content, purity and additional laboratory checks each answer a different question. Open the topics below to see what the methods tell you, how to read the results and why they matter when comparing research materials.

Start with your product and batch.

The matching report confirms which analyses were performed, their methods and results. The guide below explains the different checks; it does not replace the scope stated in that report.

Identity & molecular confirmationLC-MS / mass spectrometry

LC-MS / mass spectrometry

Identity testing addresses the first question: does the analysed material match the named peptide? Mass spectrometry provides molecular-mass information, often alongside chromatographic separation. The laboratory’s reported identification should correspond to the product and batch you are reviewing.

How to read it

Look for the sample name, identification result and method. For blends, check which components the report identifies; a result for one component does not describe the whole mixture.

Find your batch report
Peptide content & label amountQuantitative content assay

Quantitative content assay

A content assay measures the amount of the target peptide in the submitted sample. It answers a different question from chromatographic purity: how much of the named material was measured? Read the reported amount and units against the product’s labelled quantity.

How to read it

Check whether the result is expressed per vial, per sample or as a concentration. Where the laboratory provides uncertainty or an acceptance range, read that alongside the measured value.

Find your batch report
Purity & impurity profileRP-HPLC / chromatographic analysis

RP-HPLC / chromatographic analysis

Chromatography separates components so the laboratory can assess the main peptide signal and related peaks. The reported purity belongs to that method and sample. An impurity profile can also help identify synthesis-related or degradation-related components.

How to read it

Read the purity result together with the chromatogram and method where provided. Purity percentage, identity and peptide content are separate pieces of information, so review all three rather than relying on a single headline number.

Find your batch report
Microbiology & sterility checksBioburden / report-specific testing

Bioburden / report-specific testing

Microbiological analysis can measure aerobic microorganisms, yeasts and moulds. Sterility testing is a separate assessment. When these analyses are included, the report identifies the test performed and its findings.

How to read it

Check the method, units and acceptance criteria. A bioburden result should not be read as a sterility claim.

Find your batch report
Bacterial endotoxinsEndotoxin assay

Endotoxin assay

Endotoxin analysis checks for bacterial endotoxins, which can affect laboratory work. It is distinct from counting live microorganisms. The corresponding report states the method, result and applicable limit.

How to read it

Read the units and reporting limit alongside the result. Use the matching batch document to confirm whether this analysis was performed.

Find your batch report
Heavy metals & elemental impuritiesICP-MS / AAS where reported

ICP-MS / AAS where reported

Elemental analysis can measure trace metals such as lead, cadmium, arsenic and mercury. The report identifies the elements assessed, the measured amounts and any stated limits.

How to read it

Check each listed element and its units. The scope is the panel actually analysed, so a result for one element does not cover every possible contaminant.

Find your batch report
Stability, storage & handlingProduct-specific conditions

Product-specific conditions

Stability concerns how material changes over time under stated conditions. A meaningful stability result needs that context: the product form, storage conditions, time points and analyses used. A single purity report is a snapshot of the tested sample.

How to read it

Follow the product’s storage and handling information. Where stability data are supplied, check their conditions and duration before applying them to your own laboratory workflow. Contact us if you need help finding those details.

Find your batch report
Traceable batches & consistencyLot records / independent verification

Lot records / independent verification

A useful batch record links the product and lot number to an issuing laboratory, report date and analytical findings. To compare batches, review the same measurements and methods across their respective reports. A previous batch’s result does not replace the current batch’s record.

How to read it

Match the lot on your product, open its report and use the laboratory’s verification link or QR code where provided. Send us the product and batch details if you cannot find the matching record.

Find your batch report
Safety documents & research handlingMSDS / Safety Data Sheet

MSDS / Safety Data Sheet

Safety documentation serves a different purpose from a Certificate of Analysis. It supports handling, storage and other practical precautions; the COA records the laboratory findings for a sample or batch. Both can be relevant when planning your research workflow.

How to read it

Review the product information and available MSDS or Safety Data Sheet together. If a document needs clarification, our team can help locate the relevant record and answer product-specific questions.
