Quality Assurance Tabs

Verified Potency

HPLC Verified

Every vial is tested by HPLC to confirm the actual peptide content matches what's on the label, measured against a calibrated reference standard — nothing here is left to guesswork.

Why it matters: Research data depends on knowing exactly what's in the vial. A vial that's underfilled can throw off results and cost valuable research time.

Independently Verified Purity

Mass Spec Confirmed

Our compounds go through thorough mass spectrometry screening to catch impurities, degradation byproducts, and leftover synthesis materials before anything ships.

Why it matters: Higher purity means more reliable, repeatable research outcomes. Every batch is required to clear a 99%+ purity threshold.

Proven Shelf Stability

pH & Stability Verified

We run formulation and pH testing on every batch to confirm it holds up for the entirety of its labeled shelf life.

Why it matters: A properly lyophilized product should perform the same on day one as it does months later.

Screened for Contaminants

Sterility & Endotoxin Tested

Independent sterility and endotoxin testing confirms our products are free of bacteria, fungi, and other unwanted contaminants.

Why it matters: So contamination is never a variable you have to account for in your research.

Reliable Batch Consistency

QC Verified

Precise weighing and quality-control checks at every production stage keep each batch aligned to the same exacting standard.

Why it matters: The same dependable quality whether it's your first order or your fiftieth.
