Yes. Every single lot is independently tested by a certified external laboratory before it ships. Identity, purity, and potency are all confirmed, and the Certificate of Analysis is available for each batch.

Our peptides are manufactured to a minimum of 99% purity. This is documented in the Certificate of Analysis for each lot — not a general claim, but a specific, measured result for every batch we produce.

The lot number on your product label maps directly to a published Certificate of Analysis on our site. You can verify the exact lab report for your vial at any time.

Our peptides are sold strictly for in-vitro research and laboratory use. They are not intended for human or veterinary consumption, clinical use, or any application outside a controlled research setting.
