HOW EVERY BATCH IS TESTED
01
Synthesis: peptides are made by solid-phase peptide synthesis in the USA and supplied as lyophilized powder.
02
Independent testing: each batch is tested by Freedom Diagnostics, an accredited US lab, using HPLC for purity.
03
Purity: only high-purity batches are released for sale. Our average peptide purity exceeds 99%, and is verified by HPLC for each tested batch.
Our peptides are synthesized, lyophilized and tested in the USA, and we ship only to researchers within the United States. That means orders reach US laboratories quickly and without international customs delays. Same-business-day dispatch on qualifying orders helps research teams keep projects on schedule. Free shipping on orders over $200 makes it easier to stock the peptides and peptide blends your work requires. We also offer overnight shipping to ensure projects are maintained on the strictest possible time schedule.
Our online catalog is built for laboratory and in-vitro research, but others are available upon request. Our team is available by phone, email and online to answer questions about orders, documentation and shipping. Whether you run an academic lab, a private research laboratory or an independent research program, MMK Peptides aims to be a reliable, US-based source of high-purity research peptides.
