Quality assurance

Our commitment to purity isn't just a promise - it's a protocol verified with every batch.

The purity promise

99%+ verified purity

Every compound we distribute is tested to confirm minimum 99% purity. We accept nothing less, and neither should you.

Third-party testing

Independent laboratory analysis using HPLC and mass spectrometry ensures unbiased verification of every claim we make.

Batch-specific COAs

Your Certificate of Analysis corresponds to your exact lot number. Not a generic document - your specific batch, verified.

How to read your Certificate of Analysis

Every COA includes critical information about your specific batch. Here's what to look for:

Lab technician performing HPLC analysis
HPLC purity analysis in progress
Certificate of Analysis document
Batch-specific COA documentation
Temperature-controlled storage facility

Our testing process

1
Supplier qualification

We vet every supplier against strict quality criteria before accepting any materials.

2
Incoming inspection

Every shipment undergoes visual inspection and documentation review upon arrival.

3
Third-party testing

Independent labs perform HPLC purity analysis and mass spectrometry identity confirmation.

4
COA generation

Batch-specific Certificates of Analysis are generated and linked to inventory.

Storage and handling standards

Proper storage is essential for maintaining peptide integrity.

Temperature control

-20°C freezer storage for all inventory

Light protection

UV-protected storage containers and facility lighting

Humidity control

Desiccant protection and climate-controlled environment

Cold chain shipping

Insulated packaging with ice packs for all orders

Quality questions answered

Purity percentage indicates the proportion of the sample that is the intended compound, as measured by HPLC analysis. 99%+ means less than 1% of the sample consists of impurities, solvents, or related compounds.
Every COA includes a unique lot number that matches your product label. You can also search our COA library using your lot number to access your specific certificate.
Our peptides are research-grade, meaning they meet 99%+ purity standards verified by third-party HPLC testing. They are intended for research applications and are not FDA-approved pharmaceutical products.
Store lyophilized (powder) peptides at -20°C, protected from light and moisture. Once reconstituted, use promptly or store at 2-8°C for short-term use (typically 1-2 weeks).
We primarily use HPLC (High-Performance Liquid Chromatography) for purity analysis and Mass Spectrometry (MS) for identity confirmation. All testing is performed by independent, accredited laboratories.
