MIT 45 — extract-first reviewed.

Bottom line

MIT 45 is an extract-heavy kratom brand available in every US smoke shop. The Gold Shot is potent and fast-acting. The Super K Extra contains isolated 7-OH — FDA enforcement target, avoid. Usable if you understand extract pharmacology; dangerous as a first-time product.

The 7-OH problem

MIT 45's Super K Extra line contains isolated 7-hydroxymitragynine. As of 2025, this is the exact FDA enforcement target. The product is pharmacologically much stronger than either MIT 45 Gold or standard leaf kratom, and carries significantly elevated dependence risk.

If you are currently using Super K Extra regularly: you are building an opioid dependence. Taper with medical supervision if you\'ve been daily-dosing for more than a week. See the withdrawal guide.

If you\'re considering MIT 45

  • Stick to Gold Shot — skip Black and Super K Extra.
  • Max 1 shot per day — extract tolerance builds fast.
  • Minimum 2 days off per week — non-negotiable for tolerance preservation.
  • Do NOT combine with alcohol, benzos, opioids, or other sedatives.

Better alternatives

For the same underlying desired effect:

  • Leaf powder at 3–5g — 5× cheaper per mg mitragynine, slower tolerance.
  • Capsules of standard Maeng Da or Bali — same principle, easier dosing.
  • AKA-GMP certified direct-to-consumer brands — typically better lab transparency.

FAQ

Is MIT 45 stronger than OPMS?

Roughly equivalent in the extract category. Both brands dominate US smoke-shop retail. MIT 45 leans harder into the extract-only product lineup; OPMS has a broader leaf-plus-extract mix.

What does "MIT 45" mean?

MIT for Mitragynine, 45 for the standardized 45% mitragynine content of the original flagship extract. The name is now the brand identity; specific SKU potencies vary.

Should I avoid MIT 45 Super K Extra?

Yes. Super K Extra contains isolated 7-hydroxymitragynine, which the FDA is actively enforcing against. Dependence develops in days, not weeks. See our 7-OH hub.

Can I travel with MIT 45?

Within kratom-legal US states, yes. Banned states (Alabama, Arkansas, Indiana, Rhode Island, Vermont, Wisconsin) — no. International travel — check the destination's kratom laws; many countries prohibit it.

Is MIT 45 safe to mix with alcohol?

No. All kratom extracts produce additive CNS depression with alcohol. MIT 45's higher concentration makes this more acute than leaf kratom. See our interaction guide.
