Good to know

Questions, answered

Where does Hulu Kapuas Kalimantan fit on the strain spectrum?

The bag prints Mixed Strain. Our kratom strain spectrum runs White, Aged, Mixed, Green, Yellow, Orange, and Red, so Mixed is third of seven, just before Green, and many people keep it for the afternoon.

How should I start?

Start low, go slow. Take them with water and wait at least an hour before deciding on more. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

Which bag size should I pick?

The 10 capsule bag is the smallest size, a simple way to try Hulu Kapuas Kalimantan. The 30, 90, 180 and 360 capsule bags cost less per capsule as they get bigger, and you can subscribe and save on deliveries every 7, 14 or 30 days.

Is Hulu Kapuas Kalimantan lab tested?

Yes, as part of our green kratom testing. Murray-Brown Laboratories, an independent lab, tested a sample described as Korthals Green Kratom for its alkaloid content; the certificate is dated December 2025. Our Test Results page lists that same certificate for several strains, including Hulu Kapuas Kalimantan, so it is not a test of No. 411 alone. It is also linked on this page.

How do I store Hulu Kapuas Kalimantan capsules?

Reseal the bag after opening and keep it in a cool, dry place out of direct sunlight, away from children and pets.

What is kratom?

Kratom comes from the leaves of the Mitragyna speciosa tree, native to Southeast Asia, where it has been part of daily life for centuries. The leaf is dried and milled into powder, then packed into capsules, brewed, or made into extracts. Its natural leaf compounds are called alkaloids, and mitragynine is the most abundant one.

How should I start with kratom?

There is no single answer, because everyone responds differently. Start low, go slow, and give it time before deciding on more. A small kitchen scale helps if you are using powder. Like caffeine and sugar, kratom may be habit-forming. Use kratom responsibly and only as directed.

How long should I wait before taking more?

Everyone responds differently, so there is no set timeline. Start low, go slow: wait at least an hour after capsules, and at least 30 minutes after other formats, before taking more.

Can you ship kratom to my state?

We cannot ship kratom to Tennessee. Kratom is also restricted in a handful of other states and in some counties and cities. Our checkout will flag an address we are not able to ship kratom to, and the current list of restricted areas is in our site footer. If you are in a restricted area, our stores and our non-kratom selection are still open to you.

Can I pick it up in store?

Many kratom items are available for in-store pickup, and shelf selection can differ from what is online. Choose the pickup option on this page or at checkout to see which nearby locations have it in stock.
