Frequently asked

Is Borneo kratom legal? ↓
Kratom is federally legal in the US but banned in six states (Alabama, Arkansas, Indiana, Rhode Island, Vermont, Wisconsin) and regulated under the KCPA in five (Arizona, Georgia, Nevada, Oklahoma, Utah). Check our state legality tracker for your jurisdiction.
What is a standard serving size? ↓
Harm-reduction guidelines typically describe 2–4 grams as a low-to-moderate amount and 5+ grams as higher. Start with the smallest amount possible and wait 45 minutes before redosing. Tolerance builds quickly with daily use.
What does Borneo feel like? ↓
Borneo is a moderate-potency strain. Red Borneo: calm, long-duration sedation. White Borneo: gentle energy. Green Borneo: balanced.
Is it safe to mix with other substances? ↓
No. Combining kratom with opioids, benzodiazepines, alcohol, or other CNS depressants significantly increases the risk of respiratory depression and death. Do not combine with MAOIs or CYP3A4-inhibiting medications.
