The Sour Green Apple Extra Strength stick pack is one of six flavours of the same product: a 5g sachet of flavoured kratom extract carrying 200mg of mitragynine, designed to be tipped into water and drunk. It is the strongest format we review and the one that consistently sells best, largely because it solves the two things people actually complain about with kratom powder — measuring it, and drinking it.
Genuinely sour and crisp — the sharpest option here.
What you are actually buying
Each stick contains 5g of product, of which 200mg is mitragynine — the alkaloid that does most of the work in kratom. That is a concentrated extract rather than milled leaf, so the dose per gram is far higher than plain powder and the two are not interchangeable. Anyone moving across from powder should treat one stick as a full serving and nothing more.
The format matters as much as the contents. Pre-measured sachets remove the guesswork that causes most accidental overshoots with loose powder, and they travel without the mess. That is the practical case for stick packs over a bag of powder, and it is a stronger one than most vendors bother to make.
What Sour Green Apple tastes like
This is the only flavour in the range with real acidity to it. Green apple gives it a crisp, tart bite that hits first and clears quickly, and the sourness scrubs the palate in a way the sweeter flavours do not. The finish is clean — arguably the cleanest of the six — with very little lingering. The flip side is that sourness is polarising, and if you do not like sour sweets you will not last a box.
Best suited to: People who want the aftertaste gone quickly, and anyone who finds sweet drinks sickly.
How to mix it
Sharpens as it dilutes, so 12oz or more is comfortable. Cold water only — it turns odd when warm. Stir rather than shake — extract powder clumps if it hits still water all at once, and a clump that does not dissolve is a dose you did not take.
What it costs
- Single sample stick — $11.95
- 15 pack — $149.00, or $9.93 per stick
- 30 pack — $270.00, or $9.00 per stick
Buying a single stick to test a flavour before committing to a box is the sensible move, and at $11.95 it is a cheap way to find out whether you can live with the taste. Shipping is free over $50. The per-stick saving on the 30-pack is real but modest — about 25% against the single — so there is no strong reason to jump straight to the largest box before you know the flavour suits you.
Quality and lab testing
This product is on the site because it clears the same four filters everything here has to clear: a certificate of analysis from a laboratory with no commercial relationship to the vendor, stated alkaloid content that matches what the lab found, screening for heavy metals and microbial contamination, and a vendor that behaves like a real company. That last one is not a throwaway — the documented harms associated with kratom in the United States have overwhelmingly involved contamination rather than the plant itself.
A stated 200mg of mitragynine is a claim that can be checked, and it is checkable precisely because it is stated. Products that decline to put a number on the label are the ones to be careful with.
Dosing and safety
Take one stick pack at a time and do not exceed two servings in any 24-hour period. At 200mg of mitragynine per stick this is an extra strength product, and it is not where a first-time user should start — the standard-strength stick pack exists for that. If you have no tolerance, half a stick is a more sensible first serving.
For adults 21 and over only. Not for use if you are pregnant or breastfeeding. Do not combine with alcohol or other sedatives, and speak to a doctor or pharmacist first if you take prescription medication — particularly opioids, benzodiazepines or antidepressants. Kratom can be habit-forming with regular daily use. Read the full disclaimer.
Where you can buy it
Kratom is prohibited in six states — Alabama, Arkansas, Indiana, Rhode Island, Vermont and Wisconsin — and the retailer also declines to ship to Louisiana and to a number of counties and cities including Sarasota County (FL), Union County (MS), Columbus (MS), Denver (CO), San Diego and Oceanside (CA), and Jerseyville, Alton and Edwardsville (IL). Check the position in your state before ordering.
Frequently asked questions
How much mitragynine is in a Sour Green Apple stick pack?
Each 5g Sour Green Apple Extra Strength stick pack contains 200mg of mitragynine. That is a high dose by any standard — roughly what you would get from several grams of plain leaf powder — which is why this is an extra strength product and not a starting point for a first-time user.
Does the Sour Green Apple flavour change how it works?
No. All six flavours in the Extra Strength stick pack range contain the same 200mg of mitragynine in the same 5g format. Flavour affects taste only. Choose whichever you will actually enjoy drinking, because that is the only thing separating them.
How do you take a Sour Green Apple stick pack?
Empty the stick into water and stir. Sharpens as it dilutes, so 12oz or more is comfortable. Cold water only — it turns odd when warm. Take one stick pack at a time, and do not exceed two servings in any 24-hour period.

The other five flavours
Every flavour in this range carries the identical 200mg of mitragynine in the same 5g stick. The only thing that changes is the taste, so pick on that alone:
- Acai — Dark berry and tart — the best of the six at hiding the leaf.
- Strawberry — Sweet, familiar and uncomplicated — the safe first choice.
- Blue Raspberry — Loud, sweet-tart and the most effective masker in the range.
- Pineapple — Bright and tropical, with enough acidity to do real work.
- Grape — Sweet, syrupy and nostalgic — the heaviest flavour of the six.

We are not the manufacturer and we do not take the vendor's description on trust. Before this product was listed here, it went through the same four checks we apply to everything on this site.
- Independent lab results, obtained and read. We ask for the certificate of analysis from a laboratory with no commercial relationship to the vendor. A product whose results are unavailable on request does not get listed, however good the marketing is.
- Label checked against the lab. Where the product states an alkaloid concentration, we compare it with what the analysis actually shows. A meaningful gap is disqualifying — not because the product is necessarily unsafe, but because it means the vendor's quality control cannot be relied on anywhere else either.
- Contaminant screening. Specifically salmonella and heavy metals. The documented harms associated with kratom in the United States have overwhelmingly involved contamination rather than the plant itself, so absent screening is treated as a serious mark against a product.
- Vendor conduct. Verifiable business details, a returns policy that exists in writing, responsive support, and no claims that kratom treats, cures or prevents any medical condition.
What this is not. We do not run our own laboratory, and this is not a clinical evaluation. We read third-party analyses and check them against what is claimed. We publish no dosage guidance, because appropriate use depends on your physiology, tolerance and any medication you take — none of which we can assess from a web page. That conversation belongs with a qualified healthcare professional.
