Peptides 101
Peptides are short chains of amino acids linked by peptide bonds — essentially small fragments of proteins. They occur naturally throughout biology and are widely studied as signalling molecules in research.
The distinction is size. Peptides are short amino-acid chains (typically up to ~50 residues), while proteins are larger, folded chains. The chemistry is the same; the length and structure differ.
In research settings, peptides are used as reference standards and as tools to study biological pathways, receptor activity and cellular processes in vitro and in non-human models. All products are supplied strictly for laboratory and research use only and are not for human consumption.
Many peptides act as signalling molecules: in research they are studied for how they bind receptors or influence specific biological pathways. Mechanisms vary widely between individual peptides and remain an active area of scientific investigation.
Many research peptides can be purchased legally for laboratory research, but legal status varies by country and by specific compound. Buyers are responsible for knowing and complying with the laws and import rules in their own jurisdiction.
Safety profiles differ by compound and are studied in controlled research, not established for general use. Because our products are for laboratory research only, they should be handled by trained personnel following appropriate safety practices. All products are supplied strictly for laboratory and research use only and are not for human consumption.
Peptides are valuable research tools because they are highly specific, structurally defined and can help scientists probe particular pathways. This specificity makes them useful reference compounds in many areas of study.
As research compounds, peptides can be sensitive to heat, light and moisture, may have short stability windows once reconstituted, and require careful handling and storage. Results in research also vary by compound, model and conditions.
Peptides are used by academic and commercial researchers, laboratories, universities and analytical chemists who require defined compounds for study and reference.
Most research peptides are produced by solid-phase peptide synthesis (SPPS), a stepwise chemical process, after which they are purified (commonly by HPLC) and characterised for identity and purity.
It means a product is intended solely for laboratory or scientific investigation and is not approved or sold for human or veterinary consumption, diagnosis or treatment.
Lyophilised means freeze-dried. Peptides are commonly supplied as a dry, stable powder which is reconstituted with an appropriate solvent in the lab when needed for study.
Purity is the percentage of the sample that is the target peptide versus impurities. Higher purity (e.g. ≥99% by HPLC) means more reliable, reproducible research results, which is why we publish testing data.
High-Performance Liquid Chromatography (HPLC) is an analytical technique used to measure the purity and identity of a peptide. It is an industry-standard method for characterising research compounds.
Reconstitution is the laboratory process of dissolving a lyophilised (freeze-dried) peptide in a suitable solvent, such as bacteriostatic water, before it is used in research.

Product Quality & COA
A COA is a document from analytical testing that reports a batch's purity and identity. It lets researchers verify exactly what they are receiving.
Tested batches are supplied with documentation of independent purity and identity analysis. Contact support if you need the COA for a specific batch.
Tested batches are independently analysed by HPLC, with a target purity of ≥99% on tested products. The exact figure for each batch is reported on its COA.
Purity and identity testing is performed by independent third-party laboratories to ensure objective, verifiable results.
We rely on industry-standard methods including HPLC for purity and mass spectrometry for identity confirmation where applicable.
A COA typically shows the compound name, batch/lot number, test method, measured purity percentage and the testing date. The purity figure indicates how much of the sample is the target peptide.
Yes. Each tested batch has a lot number recorded on its COA. Contact support with your order to confirm batch documentation.
Contact support promptly with your order and batch details. We take quality concerns seriously and will investigate according to our quality policy.
We aim for consistency through controlled sourcing and independent testing, but each batch is individually tested and documented so you always have batch-specific data.
Impurities can confound experiments and reduce reproducibility. High, verified purity gives researchers confidence that observed results reflect the target compound.
Storage & Handling
As a general laboratory guideline, lyophilised peptides are best kept cool, dark and dry — often refrigerated or frozen for long-term storage. Always follow the specific storage notes on the product and COA.
Stored correctly (cool, dark, dry — typically frozen long-term), lyophilised research peptides are generally stable for extended periods. Refer to each product's documentation for specifics.
Once reconstituted, peptides are generally less stable and are typically kept refrigerated and used within a shorter window. Follow standard laboratory handling practice for the specific compound.
Bacteriostatic or sterile water is commonly used in laboratory settings, though the appropriate solvent depends on the peptide. We offer bacteriostatic water as a research supply.
Lyophilised peptides are stable at ambient temperatures for typical transit times, so cold-chain shipping is not usually required. Refrigerate or freeze on arrival per the product notes.
Handle research compounds in an appropriate laboratory environment using standard personal protective equipment and your institution's safety protocols.
Repeated freeze-thaw cycles and prolonged heat or light exposure can degrade peptides. Aliquoting and stable storage help preserve integrity.
Dispose of research compounds and materials in accordance with your institution's guidelines and local regulations for laboratory chemicals.
Returns & Refunds
Refunds are available if a product arrives damaged or is significantly different from its description, with photographic evidence submitted within 14 days of delivery. See our Terms & Conditions for full details.
Because these are research compounds with strict quality and integrity requirements, we generally cannot accept returns of correctly supplied products once delivered. Please order carefully.
Contact support within 14 days with your order number and clear photos of the damage. We will review and resolve it under our refund policy.
Contact support promptly with your order number and photos. If we shipped an incorrect item, we will make it right.
Once a refund is approved, processing time depends on the method and network. Crypto refunds are sent to a wallet address you provide and are typically processed promptly after approval.
Yes. Approved refunds are issued in cryptocurrency to a wallet address you supply, since payments are made in crypto.
Correctly supplied products that match their description, items reported after the claim window, and issues caused by improper storage or handling after delivery are generally not eligible.
Email our support team with your order number and supporting photos. We will guide you through the process under our published policy.
