What is 7-hydroxymitragynine? Botanical origin, how it differs from mitragynine, why extracts standardize on it, and where the published research stops.

How 7OH tablets are made, from botanical sourcing through extraction, purification, geometric blending, compression and finished-product lot testing.

7OH labeling standards explained: what a compliant kratom label must declare, how state requirements differ, and the six checks that protect buyers.

Why geometric micro blending decides whether a 7OH tablet is genuinely standardized: staged dilution, why single-stage mixing fails, and how RSD proves it.

Microbial safety testing for botanical tablets: total aerobic counts, yeast and mould, pathogen screening and why tablets are not exempt from testing.

Residual solvent testing in 7OH extracts: why extraction requires solvents, how they are removed, which are regulated and what an untested extract hides.

Heavy metal testing in kratom extracts: how plants take up lead, arsenic, cadmium and mercury, why extraction concentrates them, and what limits mean.

How to read a 7OH certificate of analysis field by field: lot numbers, test methods, specification limits, RSD, lab accreditation and the red flags.
