Understanding Our Testing Standards
We hold every batch of KO Kratom to rigorous analytical testing protocols to protect our community and ensure clean, unadulterated botanical purity.
Active Alkaloid Verification
UHPLC-DAD profiling of primary and secondary alkaloids ensures consistent potency, complete botanical entourage, and zero synthetic spiking.
- Mitragynine Floor> 1.50%
- 7-OH Natural Ceiling< 0.05%
- Secondary AlkaloidsProfiled
Heavy Metals ICP-MS
Because botanical leaves absorb nutrients from volcanic soils, ICP-MS mass spectrometry confirms our powder is free from heavy metal accumulation.
- Lead (Pb)ND (<0.05 ppm)
- Arsenic (As)ND (<0.05 ppm)
- Cadmium & MercuryND (<0.01 ppm)
Microbial & Biological Screen
State-of-the-art qPCR and plating methods screen for pathogens, coliforms, and fungal spores to ensure human-grade cleanliness and stability.
