Questions, answered.

Everything researchers ask about our material, documentation, handling and shipping — all in research-use framing. Search below or browse by topic.

Products & form
All compounds ship as lyophilized (freeze-dried) powder in sealed vials, each labelled with the compound name and a unique batch number you can look up on our Verify page.
Every lot is released against a ≥98% HPLC purity threshold. The exact measured value for your specific batch is printed on its Certificate of Analysis.
No. All PepSynex products are sold strictly as research chemicals for laboratory research use only (RUO) — not for human or veterinary use, diagnosis, treatment, or consumption.
Handling, reconstitution & storage
Sealed vials are best kept cold and dark, in line with standard laboratory practice for lyophilized research peptides. Store according to your institution’s own SOPs.
No. We supply the research material and its analytical documentation only. Reconstitution and experimental design are determined by the researcher under their own validated protocols — we do not provide dosing or usage instructions of any kind.
Lyophilized peptides are generally stable for extended periods when stored correctly and unopened. Handle and assess per your laboratory’s stability and handling guidance.
Verification & COA
Open the Verify page and search your batch number, or use the COA link on the product page. Each certificate shows HPLC purity and mass-spec identity for that specific lot.
Testing is carried out by independent third-party laboratories using HPLC for purity and mass spectrometry for identity confirmation. See About / Quality for our documented process.
Shipping & discretion
Orders ship in plain, secure, temperature-conscious packaging with no product details printed on the exterior — discretion is one of our core pillars.
Orders are processed promptly after payment clears. Transit time depends on the destination and the method selected at checkout; tracking is provided where available.
Returns, bulk & compliance
Because these are sensitive research materials, returns are handled case-by-case — contact us with your order and batch number and we’ll work it through. Full terms live in our Shipping & Returns policy.
Yes. Labs and resellers can request tiered volume pricing through our Bulk / Wholesale inquiry page, with a dedicated contact for larger orders.
