The composition helper will only help populate MedPacks for which composition has not been set already. Click the "Composition Helper" button and select all the MedPacks for which a given composition applies. E.g. We need to set the composition to 2 vials for Cycle 2 - 6 and 10: select the relevant cycles in the composition helper, set the quantity to 2 and click "Confirm". --- **![further](https://support.axiosint.com/hubfs/further.svg)Going Further** Learn more about MedPacks in the [MedPack](https://support.axiosint.com/knowledge/medpack?hsLang=en) and [MedPack Release](https://support.axiosint.com/knowledge/medpack-release?hsLang=en) articles.   -
