Understand the format
Freeze-dried products are supplied in a dry form. Some packs include a separate solution; others use a dual-chamber ampoule. Review the contents of the pack before opening it.
Follow the supplied instructions
Use the mixing method, quantities and solution supplied for that product. A method used for one formula should not be assumed suitable for another.
Check storage and use-by information
The packaging for your batch is the reference for storage and use-by guidance. If the online listing and label differ, contact support before use.
