How can you improve? Send the right stuff people pay for. I payed for a bottle of NanoRevive and received a bottle of random shit made in China named Docteat, not FDA approved and not intented to cure anything… So, 57$ direct in the trash can, cause useless to say l’ll never try to ingest that stuff. Never again, and l didn’t even try to return it cause you made it so complicated that l decided to avoid the hassle.
