Quality & Testing
What purity standard do your peptides meet?
Every compound we distribute is required to meet a 99%+ purity threshold, confirmed by HPLC prior to release.
Who performs the analytical testing?
Testing is conducted by an independent third-party U.S. laboratory, separate from our own facility, for each batch we distribute.
What documentation is published for each product?
A Certificate of Analysis (COA) is available for every lot, covering purity, identity, and endotoxin results.
How do you maintain consistency between production lots?
Each batch follows the same weighing and quality-control checkpoints, so results stay aligned from one lot to the next.
Can I access COA reports?
Yes — batch-specific Certificates of Analysis are available on our website for every product we distribute.
