The receipt is the product

We don't ask you to trust us. We ship the proof.

Every lot is sent to Brown Biology Lab — an ISO-17025-accredited, A2LA-certified independent facility — before it leaves our floor. The CoA on your shipment is the same one anyone can pull from our public library.

  • HPLC purity quantification
  • Mass spec confirmation
  • Endotoxin (LAL) testing
  • Bioburden / sterility
  • Appearance & moisture
  • Sequence verification

Receipts

Researchers don't quote feelings. They quote chromatograms.

“Five suppliers tested over six months. Apex Biohacks comes out the cleanest by HPLC, full stop.”

S. Almeida
Verified buyer · Reform Bio

“MALDI-TOF was within rounding of the calculated mass. Independent verification matched the included CoA exactly.”

Dr. A. Petrov
Independent researcher

“Mass spec on the supplied lot matched within 0.4% of the reference. Reconstitution was clean — no haze, no precipitate.”

Common questions

Before you order.

If you have a procurement-specific question (volume pricing, regulated-substance forms, custom assay panels), email research@apexbiohacks.com — we typically reply same business day.

Every lot is third-party assayed for HPLC purity, mass-spec identity, endotoxin and bioburden. Each shipment is matched to its lot's CoA — that's research-grade.
