Jetpackkratom BRONZE Liquid Extract is a purified kratom concentrate delivering 40mg of mitragynine per millilitre. Unlike raw kratom powder — which contains dozens of alkaloids in varying ratios — this liquid extract isolates the primary active constituent, giving you precise control over every drop. Available in 5ml, 10ml, and 30ml dropper bottles, it's the most discreet and portable way to dose kratom without scales, capsules, or bitter powder.
| Variant | Volume | Total Mitragynine | Best For |
|---|---|---|---|
| 5 ml | 5 ml | 200 mg | Trying the extract for the first time — roughly 25 doses at 0.2ml |
| 10 ml | 10 ml | 400 mg | Regular use over a couple of weeks |
| 30 ml | 30 ml | 1,200 mg | Best value per ml — lasts weeks to months depending on your frequency |
If you've never used a concentrated kratom extract before, start with the 5ml bottle. You'll know within a few sessions whether this format suits you, without committing to the larger size.
Kratom powder works, but it comes with trade-offs. You need a scale, you need to stomach the taste (earthy, bitter, gritty — not exactly a treat), and the alkaloid content shifts between batches. Jetpackkratom's BRONZE extract sidesteps all of that. The mitragynine has been isolated and standardised to 40mg/ml, so each dropper-full delivers a consistent, measurable amount.
The practical difference is real. A 0.2ml dose under the tongue takes about five seconds. No kitchen counter dusted in green powder, no capsule-filling sessions, no chalky smoothies. We've had customers tell us they switched to the liquid purely for the convenience at work or while travelling — a small dropper bottle in a jacket pocket draws zero attention.
The honest limitation: you're paying more per equivalent dose than you would with plain leaf or powder. That's the trade-off for standardisation, portability, and taste. If you're happy weighing powder at home and don't mind the flavour, raw kratom leaf still does the job. But if accuracy and discretion matter to you, the BRONZE extract earns its place.
Mitragynine is the most abundant alkaloid in Mitragyna speciosa (kratom), typically making up 60-70% of the plant's total alkaloid content. According to a review in the International Journal of Molecular Sciences, "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 research published in Current Pharmacology Reports, "evidence emerging from the initial preclinical findings supports the anecdotal reports that kratom can be beneficial in treating pain and mental health conditions" (PMC10177737).
At lower amounts, kratom users traditionally report stimulating, focus-enhancing effects. At higher amounts, the character shifts toward sedation and relaxation. This dose-dependent duality is one of the reasons kratom has been used in Southeast Asia for centuries — field workers historically chewed the leaves for energy during long days. The BRONZE extract's 40mg/ml concentration lets you navigate that spectrum with a dropper rather than guesswork.
A word on safety: according to a systematic review in Frontiers in Pharmacology, "cardiovascular, gastrointestinal, neurological, and psychiatric effects associated with kratom use were especially notable" at higher doses or with prolonged use (PMC9130800). This is a potent extract. Respect it accordingly.

We've stocked kratom in every format — loose leaf, powder, capsules, extracts — since the early days of the shop. The single biggest pattern we notice: people underestimate liquid extracts because the volume looks tiny. A 0.2ml dose barely covers the bottom of the dropper. But 0.2ml of this BRONZE extract packs the same mitragynine as about 2 grams of dried kratom leaf. That's not a small amount. Customers who jump straight to 0.5ml or 1ml because "it didn't look like much" tend to have a much more sedating experience than they planned for.
The other thing worth knowing: kratom interacts with liver enzymes. According to WebMD's clinical summary, kratom affects CYP2D6 and CYP2C19 pathways. If you're taking any medication metabolised by these enzymes — and quite a few common ones are — talk to your doctor first. We're not being overly cautious here; this is a genuine interaction risk that gets overlooked because kratom is a plant product. "Natural" doesn't mean "no interactions."
If you're new to kratom and the BRONZE extract sounds like too much concentration too soon, Jetpackkratom's Maeng Da Powder or Red Powder lets you start with raw leaf and work out your preferred amount before moving to extracts. Already comfortable with the BRONZE? The Jetpackkratom GOLD 80mg Extract Capsules double the mitragynine concentration in a pre-measured capsule format — no dropper needed.
Jetpackkratom labels the BRONZE extract as suitable for advanced kratom users, and we'd echo that. If you've been using kratom powder or leaf for a while and you know how your body responds to, say, 2-4 grams of dried leaf, the liquid extract is a logical upgrade for convenience and consistency. The 0.2ml suggested dose (approximately 8mg mitragynine) maps to around 2g of powder — a moderate amount for someone with tolerance.
If you've never tried kratom at all, this isn't where to start. A concentrated extract amplifies both the benefits and the risks of getting the dose wrong. Raw kratom powder is more forgiving because the alkaloid concentration is lower per gram, giving you a wider margin. Get your bearings with leaf or powder first, then come back to the BRONZE when you want precision.
Each 0.2ml dose contains roughly 8mg of mitragynine, which Jetpackkratom equates to approximately 2g of dried kratom leaf. The extract is significantly more concentrated drop-for-drop than any powder, so precise measuring matters.
Yes. The BRONZE extract mixes into tea, coffee, and juice without any issues. Citrus juice and strong black coffee mask the taste best. Just measure your dose with the dropper before adding it — don't pour directly from the bottle.
According to a systematic review published in Frontiers in Pharmacology, notable effects at higher doses include gastrointestinal discomfort, nausea, and drowsiness (PMC9130800). Prolonged daily use may lead to dependence. Stick to the manufacturer's suggested dose and take regular breaks.
Yes. Kratom affects CYP2D6 and CYP2C19 liver enzymes, which metabolise many common medications including certain antidepressants and blood pressure drugs. If you take any prescription medication, consult your doctor before using this extract.
Store it upright at room temperature, out of direct sunlight. The liquid extract stays stable for months. If it changes colour significantly or develops an off smell, replace it.
It does look tiny in the dropper, but 0.2ml delivers around 8mg of purified mitragynine — equivalent to about 2g of kratom powder. The concentration is the point. Start there and wait a full hour before deciding you need more.
BRONZE contains 40mg mitragynine per ml. GOLD doubles that to 80mg per ml and comes in capsule form rather than liquid. BRONZE gives you more flexible dosing with the dropper; GOLD is more convenient but less adjustable.
