Quality Assurance
Independently verified. Meticulously documented.
Every batch produced for HK Compounds undergoes independent third-party analysis before release. We publish a Certificate of Analysis for every lot covering identity confirmation, HPLC purity, mass spectrometry, and quantitative mg content — so your experiments rest on data you can defend.
Products are lyophilized into sealed borosilicate vials, stored under controlled conditions, and shipped in insulated packaging to protect integrity in transit.

Frequently asked
Answers to the questions researchers ask most often.
What makes HK Compounds different from other suppliers?
Our focus is purity (typically ≥99%), documentation, and consistency batch-to-batch. Every lot carries an independent Certificate of Analysis covering identity, purity, and quantitation.
Are HK Compounds products suitable for clinical or human use?
No. Every product we sell is labeled and distributed strictly for laboratory research. Our products are not intended for human or veterinary use, clinical trials, or therapeutic application.
How should I store products upon arrival?
Store lyophilized peptides at −20 °C for long-term stability (or 2–8 °C short-term). Once reconstituted, refrigerate at 2–8 °C and protect from light.
Where does HK Compounds ship?
We currently ship to research facilities throughout the United States. International availability is under review.
