QUALITY STANDARDS
EVERY LOT. EVERY TEST. EVERY TIME.
LONE STAR's quality program is built around one principle: anything we won't publish, we won't ship. Every compound is verified by third-party reverse-phase HPLC at ≥99% purity, confirmed by mass spectrometry, lot-numbered at fill, and shipped with a signed Certificate of Analysis that lives at a permanent public URL.
