Transparency report
Short answer
HALO publishes its public COA transparency standard: every active lot should have lot-specific HPLC purity, identity confirmation where applicable, third-party testing, and a batch certificate that ships with the order and is retrievable by SKU and lot number. This page documents the standard HALO holds itself to — not aggregate industry statistics.
What every active lot includes
Compound name, SKU/vial size, lot number, test date, analytical method, HPLC purity result, identity pass/fail, and a certificate of analysis that ships with the order. Product pages summarize documentation standards; digital copies are available on request with your SKU and lot number.
Third-party testing requirement
Analytical documentation is performed by independent laboratories. HALO does not treat supplier self-reported COAs as sufficient for procurement-grade records without third-party verification.
Identity testing standard
HPLC purity alone is insufficient. HALO targets identity confirmation by mass spectrometry (LC-MS, ESI-MS, or MALDI-TOF as appropriate) on peptide batches.
How to audit HALO against this standard
Use the seven-point checklist at /peptide-coa-checklist/, read /hplc-vs-lc-ms/, and match your vial lot to the COA that shipped with your order before entering material into assays.
Direct answers
Does HALO publish fake aggregate statistics?
No. This page documents HALO's COA standard and audit process — not unverified industry-wide claims.
Can institutions request documentation packets?
Yes. See /institutional-procurement/ or email [email protected] with order and lot details.
