Uncompromising Excellence: Explore Our Five Test Process

TEST ONE

Endotoxins Test:
Is it safe from hidden toxins?

See what it looks like
Even in sterile environments, bacterial residues called endotoxins can sneak in. Left unchecked, they can trigger dangerous immune reactions. Our testing ensures levels are well below safety thresholds, protecting both research outcomes and end-users.

TEST TWO

Sterility Test: 
Is it free from microbes?

See what it looks like
Lyophilization (freeze-drying) helps preserve peptides, but it doesn’t guarantee sterility. Independent labs test for bacteria, fungi, and other microorganisms to ensure the peptides are safe for sensitive research applications.

TEST THREE

Heavy Metals Test: Is it free from toxic metal contamination?

See what it looks like
We ensure zero trace of metals that can interfere with research outcomes. This to ensure every vial meets Nexus’s safety and consistency standards.

TEST FOUR

Purity Test: Is it clean and free from unwanted extras?

See what it looks like
Independent labs check that peptides are 95% pure or higher. This rules out impurities like solvents, bacterial fragments, or errors from synthesis that could reduce effectiveness or skew results.

TEST FIVE

Quantity Test: Are you getting what the label promises?

See what it looks like
We verify the exact amount of peptide in every vial. No underfilling, no fillers, no shortcuts—just the precise quantity you paid for, confirmed by unbiased testing.

TEST SIX

Identity Test: Is it really the right peptide?

See what it looks like
First, we confirm the peptide’s exact structure using advanced tools like mass spectrometry and HPLC. This ensures you’re getting the correct sequence—no mix-ups, no mislabels, no surprises.
