Research-Use-Only Compounds

New-U supplies research peptides strictly as laboratory research compounds . Here's the framing that applies in every market.

For laboratory and research use only

Research peptides such as tirzepatide, retatrutide, BPC-157, TB-500, GHK-Cu, ipamorelin and PT-141 are supplied strictly as laboratory research compounds . They are not licensed medicines and are not sold or marketed for human consumption, which is why every New-U vial ships labelled "for laboratory and research use only - not for human use."

New-U supplies laboratory research compounds direct from manufacturer to qualified researcher, with no human-use, medical or treatment claims. Legality and import rules vary by country - see our per-country pages and guides for local context.
