Koi Extra Strength Delta 9 THC Gummies
Koi Extra Strength Delta 9 THC Gummies
25mg of hemp-derived delta-9 THC with 25mg of CBD per gummy, in Strawberry, Watermelon or Blue Razz, in 20, 40 and 100 counts from $79.99 for the 40-count.
This is the strong end of Koi’s delta-9 line and it is roughly half the cost per milligram of THC of the standard gummy. The 1:1 ratio with CBD is the detail that matters: it is not just more THC, it is proportionally less CBD holding it down.
Quick Verdict: Who Is This For
Buy this if you have real tolerance and you are buying THC rather than a THC-and-CBD blend. At the 40-count it works out to about 8 cents per milligram of THC against 15 cents for the standard gummy — close to half the price for the same molecule.
Do not start here. If you are new to hemp delta-9, buy the standard Koi Delta 9 gummies at 10mg with 20mg of CBD, and take half of one.

What This Does Well
Honest two-number labelling
Koi prints both the THC and the CBD per gummy. A lot of this category quotes only the THC figure, which tells you less than half of what you need to know about how a gummy will feel.
Roughly half the cost per milligram of THC
1000mg of delta-9 for $79.99 against 600mg for $89.99 in the standard jar. If THC is what you are buying, this is the efficient way to buy it.
Only two restricted states
Unlike Koi’s delta-8 products, which are blocked in 26 states, the delta-9 line ships almost everywhere.
Pros and Cons
Pros
- 25mg delta-9 with 25mg CBD, both declared on the label
- About half the cost per milligram of THC of the standard gummy
- Three flavours and three jar sizes
- Restricted in only two states
- Batch COA behind a QR code
- 90-day refund window
Cons
- A strong dose — not a beginner product
- Less CBD relative to THC than the standard gummy, so it hits harder than the numbers suggest
- Will show on a drug test
- Not shipped to California or Oregon
Will These Get You High?
Yes. 25mg of delta-9 THC is a substantial dose for most people, and the 1:1 CBD ratio moderates it less than the 2:1 in the standard gummy. Treat one whole gummy as a real commitment to an evening.
On drug testing
Yes, this will produce a positive drug test. There is no ambiguity here. If you are tested at work, buy Koi’s broad-spectrum PRIZM products instead — see hemp THC and drug tests.
Where to Buy
Direct from Koi. Start with half a gummy even if you have tolerance, and wait a full two hours before deciding about more. Our dosing guide covers the timing.
Koi’s published refund policy gives a full refund on returns started within 90 days of purchase, and 50% back between 91 and 150 days. Shipping is free on orders over $69, and current discount codes are on our Koi coupon page.
FAQ
How much THC is in a Koi Extra Strength Delta 9 gummy?
25mg of delta-9 THC plus 25mg of CBD.
How is this different from the standard Koi Delta 9 gummy?
The standard is 10mg THC with 20mg CBD — a 2:1 ratio. This is 25mg with 25mg, a 1:1 ratio. It is 2.5 times the THC with proportionally less CBD, so the step up is larger than the numbers alone suggest.
Is it better value?
Yes, on THC. About 8 cents per milligram of delta-9 against 15 cents for the standard jar.
What flavours are available?
Strawberry, Watermelon and Blue Razz.
Which states cannot receive these?
California and Oregon.
Will they show on a drug test?
Yes. These contain real delta-9 THC in meaningful amounts.
