The Federal 7-OH Ban: Dates, Scope, What It Means
Pseudo, MGM-15, and MGM-16 are Schedule I as of August 26, 2026. The 7-OH threshold order is still pending. Dates, scope, the closed comment period, and what to do if you're still using.
Kratom Leaf & Mitragynine
Kratom basics, what mitragynine does in the body, how it relates to 7-OH, and why concentrated 7-OH products are not the same thing as leaf.
7-OH (7-Hydroxymitragynine)
Concentrated 7-hydroxymitragynine, how it differs from kratom leaf, why dependence builds fast, and what makes it taperable.
MGM-15
MGM-15 (dihydro-7-hydroxymitragynine), the long-acting reduced 7-OH. The same compound sold under the labels MIT-A and (mislabeled) DHM. Chemistry, the COA-testing problem, regulatory landscape, taper plan, Suboxone induction notes.
MGM-16
The fluorinated analog of MGM-15, a 2014 medicinal-chemistry compound named in scheduling proceedings but not documented in any US consumer product to date.
MIT-A and DHM
Products marketed as MIT-A or DHM contain MGM-15. The full picture lives on the MGM-15 page; this page is a pointer.
7-Pseudoindoxyl / MP (Mitragynine Pseudoindoxyl)
Mitragynine pseudoindoxyl (MP), receptor affinity, why bupe induction is harder, what to watch for.
Cat’s Claw
Products marketed as 'Cat's Claw' or 'Rhynchophylline' at smoke shops and gas stations are being built around corynoxine B, an opioid-active alkaloid that dodges the 7-OH scheduling. What's really in them.
