The Science of Sourcing

Independent Certification

Every batch is sent to a certified third-party laboratory. We screen for alkaloid content, heavy metals, and microbiological contaminants so you can trust what's on the label.

Sustainable Harvesting

We work directly with indigenous farmers in Southeast Asia who use wild-crafting and sustainable plantation methods. This protects the ecosystem and ensures consistent quality from harvest to harvest.

Quality at Every Step

From raw material to finished product, every step of our process happens in our own cGMP certified facility. No outsourcing, no shortcuts, full control from start to finish.

Common Questions

What makes Club13 different?

We've been a primary manufacturer since 1999, not a reseller. We control sourcing, production, and testing in-house, which means better consistency and full accountability.

Are your products lab tested?

Every product includes a lot number you can look up on our lab reports page to view the full Certificate of Analysis. We test for alkaloid content, heavy metals, and contaminants.

How should I store my products?

Keep products in a cool, dry place away from direct sunlight. Seal packaging tightly after each use. Proper storage helps maintain freshness and quality over time.

Shipping & Legality

We ship to all locations where our products are legally permitted. Check our shipping policy for details on restricted areas and delivery timelines.

Kratom Capsules vs. Powder

While powder offers versatility for tea-making, capsules provide unparalleled convenience and taste-neutrality. Each Club13 capsule is measured for exact dosage, making it the preferred choice for those with an active lifestyle or on-the-go needs.

The Alkaloid Profile

Our extraction methods focus on preserving Mitragynine and 7-Hydroxymitragynine. By maintaining the full spectrum of secondary alkaloids, we ensure an entourage effect that provides a more nuanced and beneficial experience.

Safety & Quality Standards

Club13 exceeds industry standards for cGMP compliance. Our facility is sanitized daily, and our staff follows rigorous safety protocols to prevent cross-contamination and ensure the purity of every capsule we ship.
