Why Fine Bio Labs
Quality you can document.
In a credibility-sensitive category, the proof is the product. We keep the posture serious and the documentation available — the same standard that reassures both researchers and partners.

Every compound is characterized for identity and purity, targeting ≥99% by HPLC. Specifications are stated, not implied.
COAs published
Every certificate of analysis is published in full — third-party tested, batch traceable, readable before you order. Not a summary, the document itself.
Research-use posture
Supplied strictly for research and laboratory use. Clear, serious compliance — 21+, no medical claims, no in-vivo use.
Purity figures are transcribed from certificates issued by Accurate Test Labs for batch FLL-0629.
