About 4th Quarter Labs
Built for researchers who don't compromise.
We exist to remove guesswork from the bench. Every compound we distribute is verified for identity and purity through independent third-party laboratories before it is ever assigned a batch ID.
4th Quarter Labs was founded on a simple standard: no material ships on a supplier's word alone. Incoming lots are quarantined, independently assayed by HPLC and mass spectrometry, and released only when purity clears our ≥99% threshold.
Materials arrive lyophilized, vacuum-sealed and stable — ready for reliable, reproducible in-vitro work. Fulfillment is handled domestically in discreet packaging, with batch documentation traceable from the vial in your hand back to the assay that released it.
All products are intended solely for research and laboratory purposes. They are not for human or animal consumption, medical treatment, or therapeutic use.
