No. 537 is made with full spectrum kratom extract, as printed on the can. Each 16oz can holds 75mg mitragynine, and the label serving is half a can (8oz) at 37.5mg. Pace yourself: start with half a can, wait at least 30 minutes, and only then decide on the rest.

When

When Should I Drink It?

Reach for No. 537 when you want more flavor than sparkling water: a social night out without the hangover, a slow afternoon, the walk home, or a quiet evening in. Serve it cold, over ice if you like. Half a can (37.5mg) is an easy first pour. The full can is 75mg, so save it for when you know how kratom sits with you.
