Hangzhou Mandy Biotechnology is a China-based vendor selling both retail and bulk peptides. The catalogue is small — five peptides tracked on this site — and testing documentation is limited, with vendor-hosted COAs rather than third-party lab verification. Community feedback is mixed on shipping experience, with some positive notes on product quality, though all the signal comes from a single source, so the read is still preliminary.
