Every compound is synthesized by GMP-equivalent manufacturing partners and released against a written specification. Each lot is tested for identity and purity by HPLC and mass spectrometry before it ships, and only material above 99% purity is released.
Every lot ships with a certificate of analysis, a chromatogram, and a mass confirmation issued under the YGIS quality standard. The analytical record travels with the lot, so you can review the data before use.
We also encourage every customer to verify independently. Reputable third-party labs such as Janoshik or Freedom will test a sample for you directly.
