Precision is not optional.

Built for reproducibility

Scientific research demands consistency. At Bad Witch Labs, we prioritize purity, structural integrity, and batch reliability across every compound we offer. Each product is handled under controlled laboratory conditions to support stable storage and accurate research outcomes. We do not compromise on testing standards or sourcing protocols.

High-Performance Liquid Chromatography (HPLC)

Purity verification is performed using High-Performance Liquid Chromatography (HPLC), a validated analytical method used to assess compound integrity and detect impurities. HPLC testing allows us to confirm:

• Purity percentage
• Retention time consistency
• Molecular identity confirmation
• Absence of significant contaminants

Whenever applicable, purity levels exceed 99%.

Compound verification

In addition to purity analysis, select compounds undergo identity confirmation through appropriate analytical methods, including mass spectrometry and peptide mapping techniques where applicable. These measures help confirm:

• Correct amino acid sequencing
• Expected molecular weight
• Structural consistency

Maintaining structural accuracy is critical in peptide research applications.

Controlled batch standards

Every production batch is documented and traceable. We maintain internal quality records to ensure:

• Batch-to-batch consistency
• Standardized manufacturing procedures
• Proper lyophilization protocols
• Accurate labeling and documentation

Batch numbers correspond with Certificates of Analysis when available.

Lyophilized for stability

All peptide products are supplied in lyophilized (freeze-dried) form to promote stability and extended shelf life under proper storage conditions. Each vial is:

• Sealed with a sterile rubber stopper
• Secured with an aluminum crimp cap
• Labeled clearly for laboratory identification

Storage & handling

To preserve compound stability:

• Store lyophilized peptides at recommended temperatures
• Avoid excessive light exposure
• Minimize repeated freeze-thaw cycles after reconstitution

Bad Witch Labs is not responsible for degradation resulting from improper handling after delivery.

Certificates of Analysis (COA)

Certificates of Analysis are available for select batches. Each COA includes:

• Product name
• Batch number
• Purity percentage
• Analytical method used
• Date of testing

For COA requests, please contact support with the batch number listed on your vial.
