What we test for
Synthetic peptides can contain deletion sequences, incomplete synthesis fragments, and other process-related impurities. In a research context those impurities are noise — or worse, artefacts that look like real findings. Our minimum bar is designed to keep that noise out of study material.
- HPLC purity ≥99% — high-performance liquid chromatography is the standard purity assay for synthetic peptides. Every batch is checked against this floor before dispatch.
- Identity by mass spectrometry — confirms the material matches the labelled sequence, not a substitution or truncated product.
- Third-party labs — independent accredited laboratories perform verification outside our facility so purity claims are not self-certified alone.
Certificates of analysis (COAs)
Each vial ships with a batch identifier. That ID maps to third-party purity and identity documentation. Researchers who need a COA for institutional records, protocol appendices, or quality systems can request it by emailing support@quantumlabsaus.co with the order reference or batch code.
We treat COAs as part of research hygiene — not marketing collateral. If a batch document is unavailable for any reason, we will say so clearly rather than substitute generic certificates.
Form, packing, and handling
Compounds are supplied as lyophilised (freeze-dried) powder in sealed vials unless otherwise stated. Lyophilisation maximises shelf stability for short room-temperature transit and longer refrigerated storage of unopened stock.
Reconstitution is typically performed with bacteriostatic water (0.9% benzyl alcohol). We stock bacteriostatic water as a research supply, and the free reconstitution calculator helps convert vial size and desired concentration into volume maths. For post-reconstitution dating guidance, use the storage stability tool.
Research-use framing
Every product page, the catalogue, and our site-wide disclaimer reiterate that compounds are supplied for laboratory and pre-clinical research only — not for human consumption and not as prescription medicines. Quality verification supports reproducible research; it is not a therapeutic claim.

Quality FAQ
What purity specification do you use?
Every research peptide batch is verified against a ≥99% purity specification by high-performance liquid chromatography (HPLC). Identity is confirmed by mass spectrometry so the compound on the label matches the material in the vial.
Are certificates of analysis (COAs) available?
Yes. Batch-level certificates of analysis are available on request. Contact support with your order reference or the batch identifier on the vial label and we will supply the matching documentation.
Is testing done in-house or by a third party?
Purity and identity testing is performed by accredited third-party laboratories outside our facility. Independent verification reduces conflict-of-interest risk compared with supplier-only in-house assays.
How should I store research peptides?
Lyophilised (freeze-dried) peptides are stable at room temperature for short periods and longer when refrigerated unopened. After reconstitution with bacteriostatic water, store working solutions at 2–8°C and avoid repeated freeze–thaw cycles. Use our storage stability tool for compound-specific guidance.
