In its own words: “We are a professional manufacturer focusing on the research and development, production, sales and service of peptides, pharmaceuticals and cosmetic raw materials. We have professional laboratories, researchers and high-quality factories with long-term mass production.”

We found no test results or certificates anywhere on HK Fat Cat's site.

No prices are published. You have to ask over messaging before you can compare cost against another supplier. Payment is by cryptocurrency and credit card.

Worth knowing before you order: consumer email only, no published COAs, and no research-use-only notice. Every contact address is a free consumer mailbox ([email protected], [email protected]) rather than an address on the company's own domain. There is no registered business identity behind the contact route.
