Measurement
What is an IU (International Unit)?
A dose unit used for some peptides. Not the same as milligrams.
An IU, short for International Unit, is a unit used to measure certain peptides and hormones. It is based on biological activity rather than weight, which is why it does not convert directly to milligrams.
That distinction trips people up: a label in IU and a label in mg are not describing the same kind of measurement. Conversions depend on the specific substance.
TRKD+ points out where IU shows up so you read a label correctly. It does not tell you what amount to use. A licensed provider or pharmacist is the right source for that.
