Quality You Can Verify
Every batch is tested by independent labs. See the results yourself.
Strength Verification
Every batch is checked to confirm it delivers exactly what’s on the label – no guesswork, no inflated claims. We test for actual concentration, not just what the paperwork says it should be.
Composition Check
We run HPLC analysis on every batch to confirm what’s actually inside the vial. If it’s not 99%+ clean, it doesn’t leave our warehouse.
Contaminant Screening
Beyond purity, we screen for heavy metals and residual contaminants that standard tests often skip. Research-grade means research-safe.
Sterility Assurance
Every batch is tested for microbial contamination before it’s cleared for shipping. Nothing goes out until it passes.
What Sets Keystone Apart
A smaller, more disciplined operation – built around consistency, communication, and accountability at every step.
Small Batches, Full Attention
We don't mass-produce and hope for consistency. Every batch gets checked individually before it's cleared.
