Are your peptides tested by independent laboratories?

Yes. All analytical verification including HPLC, Mass Spectrometry, microbial testing, and contaminant screening is performed by accredited third-party laboratories.

What purity standards do your peptides meet?

Most research peptides exceed 98% purity. All purity percentages are verified via HPLC and Mass Spectrometry, with supplemental tests performed when required.

Where can I access analytical test results?

All available analytical tests, including HPLC chromatograms and MS verification files, are accessible anytime through the COA & Analytical Testing Portal on our website.

Are these compounds for human use?

No. All compounds are strictly intended for scientific and laboratory research use only and are not approved for human or veterinary use.

Quality Control & Testing Standards

Q: Do you provide Certificates of Analysis?

Yes. Every batch includes a downloadable Certificate of Analysis (COA) containing chromatograms, mass spectrometry results, molecular confirmation, and complete analytical documentation.

Q: How do you maintain consistency between batches?

Batch consistency is maintained with strict QC protocols including HPLC, MS, NMR (where applicable), physical inspection, lot tracking, microbial screening, and documentation review before release.

NuScience Labs is committed to delivering high-purity laboratory research materials backed by rigorous analytical testing, certified third-party verification, and complete scientific documentation. Every batch is reviewed, validated, and tracked to ensure reproducibility, reliability, and accuracy.

Our Quality Mission

We uphold strict acceptance criteria, validated analytical testing, transparent documentation, and continuous process refinement. Our standards support researchers working with research-only materials and advanced scientific compounds.

Quality Control Process

1. Receiving & Quarantine

All incoming raw materials are quarantined and sampled before release. Each batch receives a permanent lot ID for full traceability within our documentation process.

2. Third-Party Analytical Testing

Accredited laboratories validate structure, identity, and purity using multiple analytical methods.

HPLC — Purity & Identity Verification
Mass Spectrometry (MS) — Molecular Weight Confirmation
NMR — Structural Analysis
TLC — Qualitative Identity Check
ICP-MS — Elemental & Heavy Metal Screening
GC-MS — Contaminant Detection
Microbial Panel — Pathogen Screening

3. Supplemental Testing

Certain compounds undergo expanded testing to verify chemical stability and precision.

TGA — Moisture & Thermal Stability
UV-Vis Spectroscopy — Absorption & Identity
FTIR — Functional Group Verification
Titration — Quantitative Composition

4. In-House Verification

Solubility Testing — Solvent Compatibility
Melting Point Analysis — Identity Verification
Organoleptic Review — Visual/Physical Checks
Foreign Material Inspection — Particulate Screening

5. Final Review & Release

Only materials that pass every required step are released. Full analytical data is maintained with batch documentation for researcher reference.

Our Commitment to Researchers

We support reproducible, responsible laboratory research by prioritizing accuracy, verification, and documentation transparency across every release.
