- 7-OH (7-hydroxymitragynine)
- An alkaloid linked to the kratom tree. Kratom leaf has only trace amounts; 7-OH products contain a measured, concentrated amount. What is 7-OH? →
- Alkaloid
- A naturally occurring compound found in plants. Kratom leaf contains dozens; mitragynine is the most abundant.
- Kratom (Mitragyna speciosa)
- A tree in the coffee family native to Southeast Asia. Its leaves are sold as powder, capsules and teas. 7-OH vs kratom →
- Mitragynine
- Kratom's main alkaloid. The body converts some of it into 7-OH, and 7-OH products are generally made from it.
- COA (certificate of analysis)
- A lab's report of what's in one batch of a product: potency and contaminant results. How to read a COA →
- Batch (lot) number
- The code that identifies one production run. It should be printed on your pack and match the COA.
- Third-party lab
- An independent testing lab with no stake in the product — not the brand testing itself.
- ISO/IEC 17025
- The international accreditation standard for testing laboratories. Look for it on a COA.
- Potency
- How much of an active compound a product contains — for 7-OH, usually in mg per tablet or as a percentage.
- Heavy metals panel
- Lab tests for lead, arsenic, cadmium and mercury.
- Residual solvents
- Chemicals left over from extraction. A COA should show them below safe limits.
- Microbials
- Lab tests for mold, yeast and bacteria such as E. coli and salmonella.
- mg per tablet
- The amount of 7-OH in one tablet — the headline strength on a pack. Strengths explained →
- Total mg
- All the 7-OH in a pack: number of tablets × mg per tablet.
- Serving
- The amount the label defines as one use. It can be smaller than a whole tablet.
- Price per mg
- Pack price divided by total mg — the fair way to compare value across products.
- Scored tablet
- A tablet pressed with a line (or a cross, if quarter-scored) so it breaks into equal parts.
- Chewable tablet
- A tablet made to be chewed, usually flavored.
- Blister pack
- Packaging that seals each tablet in its own plastic bubble with a foil back.
- Restricted state
- A state that bans or regulates 7-OH. We don't ship to them. Where we can't ship →
- 21+
- 7-OH is sold only to adults 21 and over. Buyers confirm their age at checkout.
