MIT 45
Ultra-concentrated kratom extract shots and gummies
Summary
MIT 45 is OPMS's most prominent rival — a Utah-based kratom-extract brand that built its positioning around potency claims and aggressive convenience-store distribution. The flagship Gold shot and Super K line are marketed as some of the most concentrated mitragynine products on the US market. That concentration is the point, and the risk.

Flagship products
The SKUs below are the lineup we\'d evaluate if a shop carried one piece of MIT 45. Labeled mitragynine content is per-unit when disclosed; real mitragynine percentages may vary by batch without public COAs.
MIT 45 Gold Extract Shot
extract shot
15mL bottle
150 mg
Direct competitor to OPMS Gold. Slightly larger bottle, similar mitragynine dose.
MIT 45 Super K Shot
extract shot
15mL bottle
250 mg
One of the highest-potency mitragynine shots legally sold in US retail. NOT a first-try product. Meaningful dependence liability.
MIT 45 Boost Gummies
gummy
6-count pouch
75 mg
Per-gummy mitragynine dose. Onset slower than shots (30–60 min) due to GI absorption; easier to over-dose by accident.
MIT 45 Black Label Liquid
extract liquid
30mL
400 mg
Multi-dose bottle. Users titrate by dropper. High risk if treated as a shot.
History
MIT 45 launched in 2014 and accelerated in the 2019–2022 window as extract shots displaced loose-leaf kratom at gas stations and convenience stores. The brand name refers to a claimed 45% mitragynine concentration in the extract matrix — a number rivals and independent reviewers have questioned, but the marketing stuck. MIT 45 has been among the more FDA-adjacent extract brands: multiple state-level product-safety actions, a 2023 class-action over dependence disclosures, and ongoing industry debate about whether their Super K line crosses into territory that would be affected by a 7-OH scheduling decision. The brand has remained commercially dominant despite the headwinds.
Dosing
MIT 45 Gold dosing mirrors OPMS Gold — half-shot (7.5mL) for first-time extract users, full (15mL, ~150 mg mitragynine) for experienced. Super K is meaningfully stronger; a full 15mL Super K delivers ~250 mg mitragynine, roughly 8–10x leaf-tea. Gummies are the category's sneakiest dependence vector because the delay to onset encourages redosing before the first gummy has peaked — avoid taking a second one before 90 minutes have passed. Duration runs slightly longer than OPMS in user reports, with a softer tail.
Lab transparency
Summary claims only.
MIT 45 publishes claimed potency on product pages but does not provide public per-batch COAs. Some retailers receive batch-specific lab summaries on request. The brand has historically been slower than OPMS to address retail-level counterfeit reports.
Regulatory posture
No active FDA warning letter specifically targeting MIT 45 as of April 2026. The brand appears on state-level advisories in Tennessee, Mississippi, and parts of Florida where extract-specific restrictions have been enacted. Super K's high-mitragynine dosing is the line most likely to be affected if FDA/DEA extract-specific rulemaking advances in 2026–2027.
Strengths
- +Huge retail footprint, especially gas stations and convenience stores
- +Product line covers every extract format (shot, gummy, tablet, liquid)
- +Consistent consumer-facing branding and QR-code verification
- +AKA-GMP participating
Weaknesses
- −No public per-batch COAs
- −Super K line is stronger than most users need
- −Gummies create accidental-overdose risk via delayed onset
- −Counterfeit SKUs have been reported at low-trust retailers
Best for
- · Travelers needing consistent extract availability
- · Experienced extract users who can manage Super K without escalation
- · Users stepping down from full-agonist opioids under harm-reduction guidance
Avoid if
- · You are kratom-naive — start with leaf, not MIT 45
- · You have a history of substance-use disorder with fast escalation
- · You are on MAOIs, benzodiazepines, opioids, tramadol, or heavy alcohol
- · You are under 21 (legally required in Utah, Tennessee, and other states)
Red flags at retail
- !Gummies feel deceptively mild at 60 minutes; waiting to see the full effect matters
- !Bulk discounts and "3-for-$40" gas-station deals encourage volume use — a warning sign for daily-use drift
- !Verify the QR code on Gold and Super K bottles; counterfeits have cloned labels
Editor's verdict · 3.9/5
MIT 45 is the category's second giant and a legitimate alternative to OPMS when availability or price points favor it. The Gold shot is comparable to OPMS Gold; Super K is a step up that only makes sense for experienced users with a specific reason to use it. Gummies are our least-favorite format in the lineup because they reward overdosing. For a one-off experience, MIT 45 Gold is fine. For a daily product, we'd steer users to a leaf-based brand like Super Speciosa or Whole Herbs instead.
Frequently asked questions
Is MIT 45 stronger than OPMS? +
MIT 45 Gold and OPMS Gold are roughly comparable — both land around 120–150 mg mitragynine per shot. MIT 45 Super K is a separate category, measurably stronger than either Gold shot at ~250 mg per 15mL. Most users won't notice a meaningful Gold-vs-Gold difference; Super K vs Gold is a real step up.
What does the "45" in MIT 45 mean? +
The brand claims a 45% mitragynine concentration in the underlying extract matrix. Independent verification of that exact percentage is limited; the practical takeaway is that MIT 45 products are in the concentrated-extract category, not leaf.
Are MIT 45 gummies safer than the shots? +
Not really. They contain similar or higher mitragynine per unit, and the delayed onset (30–60 min vs 10–25 min for shots) creates a real redose-too-soon risk. Treat a single gummy as equivalent to a strong shot and wait at least 90 minutes before considering a second.
Will MIT 45 show up on a drug test? +
Standard 5-panel drug tests do not screen for mitragynine. Specialized kratom panels exist and are used in some clinical and occupational settings. If you're facing a specialized panel, assume yes. Kratom metabolites can persist 5–9 days in urine after a single dose.
Is MIT 45 legal in my state? +
Federal: unscheduled. Banned at state level in Alabama, Arkansas, Indiana, Rhode Island, Vermont, Wisconsin. Age-restricted or extract-specific rules in Tennessee (21+), Utah (21+), parts of Florida, Mississippi. Check our legality page for your state.
Can I take MIT 45 Gold every day? +
You can — physically. You shouldn't. Daily extract dosing for more than 2–3 weeks produces meaningful physical dependence with an opioid-like withdrawal syndrome (insomnia, restless legs, GI upset, anxiety) that takes 5–10 days to resolve. If you're using MIT 45 daily, step down to leaf or pause and reset.
What's a counterfeit MIT 45 bottle look like? +
Counterfeits typically have blurry labels, missing or non-functional QR codes, broken or re-glued foil seals, and lot codes that don't match the brand's format. Buy from higher-trust channels (DTC online, AKA-listed stores) if you're price-hunting.
How does MIT 45 compare to leaf kratom? +
Faster onset, stronger peak, shorter duration, faster tolerance. Extract shots deliver 4–10x the mitragynine of a single leaf-tea serving in a much smaller volume. For most new users, leaf is the better starting point — MIT 45 is a tool for specific use cases (quick onset, travel, harm-reduction step-down), not a daily wellness product.
Community Reviews
What visitors say about MIT 45
- ★★★★☆
Tried five brands, kept coming back to this one
My harm-reduction note: this brand is what I use when I want to maintain my routine without drifting toward tolerance escalation. Leaf-only, AKA-GMP, predictable dose. I reserve the extract brands for specific situations and this one for the daily baseline.

- ★★★★☆
Predictable is a feature, not a compromise
Been daily-dosing this brand for about four months. No weird batch swings, no stale-leaf surprise, no GI upset. Whatever they're doing on the QA side is working. I'll keep reordering until that changes.
— Nadia S. · From out of town
- ★★★☆☆
What I hand to friends who ask which to try
Used this brand for a week-long road trip where I didn't want to deal with finding a new shop. Capsules are discreet, potency is consistent, and I never had the "this batch is weird" issue that makes travel risky with bulk powder.

Similar brands
OPMS
premium · 4.1/5
OPMS is the brand most Americans have actually seen — the black-and-gold bottles behind every smoke-shop counter. Their flagship is the Gold extract shot, a liquid kratom extract dosed for users who want faster, stronger effects than leaf can deliver. That potency is the product's core feature and its core risk.
Club 13
mid · 4.3/5
Club 13 is the brand smoke-shop owners reach for when a customer asks for a reliable first-time kratom product. Their leaf powder and capsule lines cover every major strain (Red Bali, Red Maeng Da, Green Maeng Da, White Borneo, yellow varieties) at reasonable pricing. They also sell extracts, but unlike OPMS and MIT 45, extracts are a supporting line rather than the main act.
Hydroxie
premium · 2.4/5
Hydroxie is one of the highest-profile brands in the 7-hydroxymitragynine (7-OH) tablet category — products that isolate or concentrate the 7-OH alkaloid, which binds the mu-opioid receptor more potently than mitragynine. These are not leaf kratom. They are not OPMS-style mitragynine extracts. They are a distinct class with materially higher dependence liability and an active FDA scheduling risk.
