We supply academic institutions, biotechnology companies, diagnostic laboratories, and independent researchers conducting pre-clinical work. Buyers are required to represent that they hold certified chemical or academic researcher credentials, and that the compounds will be used strictly within a laboratory setting.

We do not supply individuals for personal use under any circumstances.

No. Every product we distribute is classified for in-vitro and laboratory research use only.

Yes. Multi-vial and repeat-batch arrangements are quoted per project rather than through a fixed price list, because lead time depends on sequence complexity and the purity threshold requested.

Send your target sequences, quantities, and required purity floor through our contact page and a technician will return a written quote.

Custom solid-phase peptide synthesis is available for research sequences. We will need the full amino acid sequence, any required modifications, the target quantity, and your purity requirement.

Custom work carries a longer lead time than catalog items, and every custom batch ships with its own third-party analysis.

Our stated floor is >99.8%, with an average batch purity of 99.87% across recent production. Maximum residual free acid (TFA) is held at 0.05%.

Two independent methods are used on every batch:

• HPLC — high-performance liquid chromatography establishes the integrated area of the target peak against total detected area.
• MALDI-TOF mass spectrometry — confirms the exact isotopic parent mass, verifying the amino acid sequence rather than only its purity.

Analysis is performed by an independent third-party laboratory, not in-house, so the certificate is not self-issued.

A Certificate of Analysis is the third-party chromatography sheet for the specific batch your vial came from. It records peak retention time, integrated area, impurity percentage, and confirmed molecular mass.

Each vial carries a batch identifier printed on the label. Quote that identifier in an enquiry and we will return the matching certificate for your records.

Receptor binding models are highly sensitive to impurity ratios. A variance of even 1% between lots can produce anomalous activation responses, which means results from two batches are no longer directly comparable.

This is the reason our synthesizers are calibrated for identical molecular weight and sequence alignment across production runs, rather than being tuned per batch.

All compounds ship as a dry, lyophilized (freeze-dried) cake. They are not sterile-reconstituted prior to dispatch.

Research models therefore require preparation with a bacteriostatic liquid before use in an assay.

Peptide bonds degrade far faster in solution than in a dry state. Freeze-drying under strict vacuum parameters removes moisture, which maximises peptide bond lifetime and allows the material to survive standard shipping cycles without loss of molecular integrity.

A vial shipped in solution would begin degrading in transit, and its stated purity at dispatch would no longer describe what arrives.

Concentration is determined by vial mass and diluent volume. Total peptide in micrograms equals vial size in milligrams multiplied by 1,000; dividing that by your diluent volume gives concentration per millilitre.

Our Precision Reconstitution Calculator performs this conversion and expresses the result in U-100 syringe units for measured laboratory draws.

Guidance varies by sequence, so always follow the storage line on your batch certificate. As a general rule:

• Unopened lyophilized vials remain stable longest when kept cool, dry, and shielded from light.
• Once reconstituted, material should be held under refrigeration at 2–8°C.
• Repeated freeze-thaw cycling degrades peptide integrity and should be avoided.
• Sanitize vial stoppers before every draw to prevent contamination of the remaining volume.

If your protocol requires a specific stability window, request the batch-specific data before you plan the assay schedule.

Three preparation tiers are offered at checkout or quote stage:

• Ambient dry lyophilized — standard, no additional charge.
• Cold pack (2–8°C thermo shield) — standard for temperature-sensitive sequences.
• Dry ice (−78°C carbon dioxide courier) — for extended transit or specialist requirements.

Because material ships dry, ambient transit is appropriate for most catalog sequences. If you are unsure which tier your protocol needs, ask before ordering.

Standard processing runs 5–7 working days. Urgent priority compounding is available for time-boxed studies, and flexible academic scheduling is offered where a delivery window is not critical.

Custom sequences take longer than catalog items because synthesis and third-party analysis both have to complete before dispatch.

Do not use the material in an assay. Photograph the vial, the label, and the packaging as received, then contact us with your batch identifier and order reference.

Compromised transit means the purity on the certificate can no longer be assumed to describe the vial in front of you, which makes any data generated from it unreliable.

All compounds are synthesized in the USA. International availability depends on the destination country's own rules for research chemicals, and on your institution being able to receive them lawfully.

Enquire with your destination and institutional details before ordering so we can confirm whether we are able to ship to you.

No. Our compounds are research chemicals, not approved drugs. They have not been evaluated or approved by the FDA for any therapeutic, diagnostic, or preventive use, and no such use is implied by anything on this website.

Our Nevada facility operates to ISO 9001:2015 manufacturing criteria, with ISO 5 (Class 100) sterile cleanrooms for vial filling and automated high-throughput solid-phase synthesizers for production.

Batch analysis references American Gerontology Association standard reference codes.

All pathway and mechanism descriptions on this site are derived from published medical journals and pre-clinical models. They describe what has been observed in research literature.

They are not claims about outcomes in humans, and should not be read as such.

Resale requires a written wholesale arrangement with us. Onward distribution carries the same restriction that applies to the original purchase: research use only, never for human or veterinary application.

If you intend to distribute rather than consume the material in your own studies, contact us so the terms can be agreed in writing first.
