Full-Panel Testing Beyond Purity

Our Full-Panel Testing Includes:

Identity Testing

Confirms the peptide matches its intended molecular structure.

Purity Analysis

Measures the target compound present within each batch.

Sterility Testing

Confirms the absence of microbial contamination.

Potency Verification

Ensures accurate concentration and consistency.

Heavy Metal Screening

Tests for contaminants including lead, mercury, arsenic, and cadmium.

Screens for solvents remaining from manufacturing.
