Kratom tinctures
by Jetpackkratom
Jetpackkratom GOLD Liquid Extract is a concentrated kratom tincture standardised to exactly 80mg of mitragynine per millilitre — the equivalent of roughly 8g of dried powdered leaf in a single ml. Where loose powder leaves you guessing with kitchen scales and inconsistent batches, this liquid extract removes the uncertainty entirely. Measure your dose with the included pipette, place it under your tongue, and you know precisely what you're getting.
Three bottle sizes, same concentration. The difference is simply how long they last.
| Variant | Volume | Total Mitragynine | Best For |
|---|---|---|---|
| SM0396 | 5 ml | 400mg | First-timers wanting to test the waters — enough for 10 doses at 0.5ml |
| SM0236 | 10 ml | 800mg | Regular users who know their dose and want a couple of weeks' supply |
| SM0231 | 30 ml | 2,400mg | The best value per ml — a solid month-plus for most people |
If you've never tried kratom extract before, we'd grab the 5ml bottle first. Once you've dialled in your sweet spot, the 30ml makes far more sense economically.
Powdered kratom leaf varies wildly in mitragynine content — anywhere from 1% to 2% depending on the harvest, the drying process, and how long it's sat on a shelf. That means your "5 gram dose" could contain 50mg of mitragynine one week and 100mg the next. With Jetpackkratom GOLD, every batch is lab-tested to confirm 80mg per ml, so you're not playing a guessing game with your body.
There's also the taste. Let's be honest: kratom powder is bitter. Properly, aggressively bitter. Toss-and-wash veterans know the drill, but it never gets pleasant. The liquid extract is still bitter — no one's managed to make mitragynine taste like mango — but you're dealing with a fraction of a millilitre under your tongue rather than spoonfuls of green powder. It's a different order of magnitude in terms of convenience.
The one honest limitation: liquid extracts cost more per equivalent dose than raw powder. You're paying for the extraction, the standardisation, and the lab testing. If you're already comfortable with powder and a decent scale, you might not need this. But if consistency and convenience matter to you — and they should, especially with a dose-dependent botanical — the GOLD extract is the cleanest way to get there.
Kratom (Mitragyna speciosa) has been used in Southeast Asia for well over a century, with the first documented reports of its traditional use dating back to 1836, and mitragynine — its primary active alkaloid — first isolated in 1907. The body of modern research is still catching up with that history, but some findings are worth knowing.
According to a review in Current Pharmacology Reports (2020), "in addition to its opioid-like analgesic effects, mitragynine appears to block pain signalling through other mechanisms as well, suggesting a multimodal approach" (PMC7203303). And according to a 2023 clinical review, "evidence emerging from the initial preclinical findings supports the anecdotal reports that kratom can be beneficial in treating pain and mental health conditions" (PMC10177737). That said, a separate systematic review noted that "cardiovascular, gastrointestinal, neurological, and psychiatric effects associated with kratom use were especially notable" at higher doses or with prolonged use (PMC9130800).
The takeaway: kratom is pharmacologically active, dose-dependent, and not something to be casual about. Low amounts and high amounts produce distinctly different effects. Start conservatively, pay attention, and don't stack it with other substances — especially anything that affects the same liver enzymes (more on that below).
Kratom alkaloids — particularly mitragynine — interact with liver enzymes that process a wide range of other substances. Research has shown that kratom extracts inhibit CYP2D6 by approximately 90% and CYP2C9 by approximately 65% at tested concentrations (PMC12084173). In plain terms: if you're taking anything metabolised by those enzymes — and that includes many common medications — kratom could cause those substances to build up in your system to unpredictable levels.
Do not combine kratom extract with alcohol, benzodiazepines, opioids, or other CNS depressants. Don't mix it with MAOIs. If you're on any prescription medication, speak to your doctor or pharmacist before using this product. We know that sounds like a standard disclaimer, but CYP2D6 inhibition at 90% is not trivial — that enzyme processes codeine, tramadol, many antidepressants, and more.
Regular use can lead to tolerance and dependence. According to StatPearls (NCBI), kratom has "physiological effects similar to opioids" and withdrawal symptoms have been documented with sustained daily use (NBK585120). Use it occasionally, not as a daily habit. We've seen customers over the years who started with "just weekends" and gradually crept into daily territory — keep yourself honest about frequency.

Pair it up: If you're weighing up liquid extract versus traditional powder, we also carry Jetpackkratom's dried kratom powders and capsules. Capsules are a solid middle ground — pre-measured, no taste, though not as precisely standardised as the GOLD extract. And if you're looking for a precision milligram scale to double-check your liquid doses by weight, a digital scale accurate to 0.01g is worth having in your kit.
We've sold kratom in various forms for years — loose powder, crushed leaf, capsules, extracts. The single biggest issue customers run into with powder is inconsistency. You find a dose that works, you reorder the same strain, and suddenly it hits completely differently because the alkaloid content shifted between harvests. With a product standardised to 80mg/ml and batch-tested, that variable disappears.
The pipette dosing also matters more than people realise. At 80mg per ml, each 0.1ml increment represents 8mg of mitragynine — roughly a gram of leaf equivalent. That kind of granularity lets you fine-tune in a way that's genuinely difficult with powder, even with a good scale. Powder clumps, sticks to the scoop, absorbs moisture. Liquid doesn't have those problems.
The honest trade-off is cost. Millilitre for millilitre, extract is more expensive than buying bulk powder. If you go through large amounts regularly, the maths may not work in your favour. But for precise, occasional use — where you want to know exactly what you're taking every single time — the GOLD extract is the best kratom dosing method we've come across.
At 80mg mitragynine per ml, a 0.5ml dose delivers 40mg of mitragynine. That's roughly equivalent to 4g of average dried kratom leaf. It's a moderate starting point — enough to gauge your sensitivity without overdoing it.
No. Kratom and alcohol both depress the central nervous system, and combining them increases the risk of excessive sedation and respiratory issues. Keep them well apart — ideally not even on the same day.
This is common. Some people need 2–3 sessions before the effects become noticeable. Your brain's opioid receptors may need initial exposure to respond to mitragynine. Don't increase the dose after one try — repeat the same 0.5ml dose a few times first.
Yes, it's bitter. Less unpleasant than choking down spoonfuls of powder, but still distinctly bitter. Dropping your dose into black coffee or a strong citrus juice masks it well. Holding it under your tongue for 30 seconds is the fastest route to absorption, though.
Keep it in a cool, dark place — a cupboard or drawer away from direct sunlight and heat. The extract is concentrated and stable, but UV light and warmth degrade mitragynine over time. No need to refrigerate, but it won't hurt if you do.
We'd strongly advise against daily use. Research documented in StatPearls (NCBI) confirms that sustained daily kratom consumption can lead to tolerance, dependence, and withdrawal symptoms. Treat it as an occasional tool, not a daily supplement.
Yes, significantly. Kratom inhibits CYP2D6 and CYP2C9 liver enzymes, which metabolise many common medications including certain antidepressants, painkillers, and blood thinners. If you take any prescription medication, consult your doctor or pharmacist before using this product.
Jetpackkratom's GOLD line is standardised to 80mg mitragynine per ml and batch-tested for consistency. "Gold" typically refers to a blend or specific drying process that produces a balanced alkaloid profile. The key differentiator here is the lab-verified concentration — you know exactly what each ml contains.
