Frequently Asked Questions

Solyn applies a structured quality evaluation process to support consistency, reliability, and traceability of its research materials. Each production batch is evaluated using analytical methods appropriate for the compound and its intended laboratory application. These evaluations typically include identity confirmation, purity analysis, and quantity or assay verification. Where applicable, additional contamination screening—such as sterility, bacterial endotoxins, or heavy metals—may also be performed.

Acceptance criteria can vary depending on the compound and analytical method. The definitive specifications and test results for each batch are documented on that batch’s Certificate of Analysis (COA), which serves as the authoritative reference. Solyn also reviews and updates testing approaches over time as analytical standards evolve and research needs change.

Yes. Solyn provides a Certificate of Analysis (COA) for each production batch released for sale. COAs are issued on a per-batch basis and document the analytical testing performed on that specific lot. The COA is the definitive source for confirming identity, purity, assay, and any additional testing performed for that batch.

COAs are intended to support transparency and allow researchers to evaluate whether a specific batch meets the requirements of their experimental workflow.

A Solyn COA typically includes confirmation of compound identity, with the analytical method clearly noted. Purity results are commonly reported, often determined by high-performance liquid chromatography (HPLC), and chromatograms may be included when applicable. Quantity or assay information is also provided, indicating the measured amount of active material relative to the labeled claim.

When applicable, COAs may also include sterility testing, bacterial endotoxin screening, or additional analytical panels such as heavy metals. All methods used are listed directly on the COA so researchers can interpret the data within the context of their protocols.

Purity and assay measure different aspects of a compound’s quality. Purity describes how much of the desired compound is present relative to related or impurity compounds. Assay, on the other hand, measures how much active material is present compared to the stated label claim.

A product may exhibit high purity while still deviating from the labeled quantity. For this reason, both values are reported independently on the COA to provide a complete analytical picture.

Solyn may accept returns of unused, unopened, and undamaged products within a defined period after delivery, subject to review. Because Solyn supplies laboratory research materials, returns are evaluated carefully to maintain quality integrity and regulatory compliance. Opened, used, or compromised vials are generally not eligible for return.

Return eligibility is determined on a case-by-case basis once Solyn Support reviews the request.

To request a return, customers should contact Solyn Support and provide their order number along with details of the item(s) they wish to return. If the request is approved, Solyn will issue a return authorization and provide specific shipping instructions.

Returned items must be packaged securely and shipped using a trackable shipping method. Return instructions provided by Support should be followed closely to avoid delays or rejection.

In certain circumstances, exceptions may be considered. These can include shipment errors, transit-related damage, or other issues identified shortly after delivery. Each exception request is reviewed individually based on the facts of the situation and applicable compliance considerations.

Solyn products are supplied strictly for laboratory research and development use only (RUO). They are intended for use in academic, commercial, and scientific research environments and are not approved for human or veterinary diagnosis, treatment, prevention, or cure of any disease or condition.

To remain compliant with RUO requirements, Solyn may request confirmation of intended laboratory use before accepting or shipping certain orders. Orders that appear inconsistent with RUO use may be declined.

No. Solyn products are not approved for medical use and are not intended for human or animal consumption. They must not be ingested, injected, or otherwise administered to humans or animals.

Solyn cannot provide medical or legal advice. Customers are responsible for ensuring that their use of Solyn products complies with all applicable laws, regulations, and institutional requirements.

Most Solyn peptides are supplied as lyophilized (freeze-dried) powder in sealed glass vials. Lyophilization supports long-term stability and helps reduce degradation during storage and shipping.

In some cases, certain compounds may be offered in alternate formats or bulk packaging when noted on the product page and corresponding COA. Researchers should always review product listings and COAs for format-specific details.

In some cases, yes. Solyn periodically expands its catalog and may evaluate requests for compounds that are not currently listed. Customers should contact Solyn Support and provide detailed information such as compound name, sequence (if applicable), desired quantity, testing expectations, and any timeline considerations.

Requested products may require additional sourcing, method development, and third-party verification. As a result, evaluation timelines can range from several weeks to longer, depending on complexity and feasibility. Some requests may ultimately be declined due to quality, compliance, or sourcing constraints.

If your order arrives with damaged packaging or contents, document the issue immediately. Take clear photos of the shipping box (all sides), shipping label, and the damaged items. If internal packaging is damaged, photograph it before removing any contents.

Contact Solyn Support as soon as possible with your order number, photos, and a brief description of the damage. Please retain all original shipping materials until the issue is fully resolved, as carriers may require inspection or additional documentation.

Solyn is a U.S.-based, remote-first organization. Order fulfillment is handled through vetted U.S. logistics and shipping partners. For security and compliance reasons, warehouse and fulfillment addresses are not publicly listed.

If a return is authorized, Solyn Support will provide a return address and instructions as part of the return authorization process.

No. Solyn does not currently offer in-person visits, walk-in pickups, or on-site order collection. All orders are shipped through authorized fulfillment and logistics partners.

Each product vial or package includes a batch or lot code that corresponds to its COA. If a QR code is present on the label, scanning it will retrieve the matching COA. If you are unable to locate your COA, contact Solyn Support and provide your order number along with the batch or lot code.

Support can assist in retrieving the correct documentation for your purchase.

Solyn peptides are often supplied as lyophilized powder and require reconstitution before use in research protocols. Reconstitution should be performed using appropriate laboratory techniques, aseptic handling, and suitable diluents consistent with your protocol.

General best practices include allowing materials to reach room temperature, adding diluent slowly along the vial wall, and gently swirling or rolling the vial rather than shaking. Because reconstitution requirements can vary by sequence and application, researchers should consult relevant literature and internal protocols.

If you are uncertain whether a Solyn product is appropriate for your laboratory workflow, regulatory environment, or analytical requirements, contact Solyn Support before placing an order. Providing details about your intended application allows Support to offer guidance or recommend alternative options when available.
