Koi Review: Three Categories, Three Different Risks
Koi sells CBD alongside delta-8 and delta-9 THC gummies, THCA flower and mushroom-infused chocolate bars, mostly in the $59.99 to $99.99 range. These are not one category with one risk profile. Plain CBD, semi-synthetic delta-8, THCA flower and mushroom edibles each raise different questions, and the last of those has a documented safety history that any review owes the reader.
Verified August 25, 2026. Koi sells hemp and cannabinoid products, not medicine. None of it is a weight-loss product. For weight-loss medication see our GLP-1 provider rankings.

Verdict: A visible brand in a category whose regulatory footing is far shakier than its packaging suggests. Koi states third-party lab testing and restricts sales to adults 21 and over, both of which are the right baseline. The problems are structural rather than brand-specific: delta-8 is typically produced by chemical conversion from CBD and the FDA has warned about adverse events and process byproducts; THCA flower is intoxicating once heated and its legal position varies by state; and mushroom-infused edibles are the category where a nationwide illness outbreak occurred. Ask for a batch-matched certificate of analysis before buying anything here.
What Koi Costs
Pricing clusters between roughly $59.99 and $99.99 across categories.
| Plan | What you get | Listed | Real cost |
|---|---|---|---|
| CBD gummies | Non-intoxicating | About $59.99 | Lowest-risk category here |
| Delta-8 / delta-9 gummies | Intoxicating | About $79.99 to $89.99 | Semi-synthetic production concerns |
| THCA flower | Intoxicating when heated | About $84.99 | Legal position varies by state |
| Mushroom chocolate bars | Varies by formulation | About $99.99 | The category with an outbreak history |
Mushroom-infused edibles: what happened in this category
In 2024 the FDA and CDC investigated illnesses linked to a brand of microdosing mushroom chocolate bars. The CDC reported 180 cases across 34 states, 73 hospitalisations and three potentially associated deaths, with symptoms including seizures, loss of consciousness, abnormal heart rate and blood pressure. Testing found muscimol, a compound from amanita mushrooms, and in some bars a synthetic psychedelic. The manufacturer recalled its products. That was one brand and this is a different one — but it demonstrates that the category has shipped undisclosed active compounds at scale, with no meaningful pre-market oversight. If you buy anything in this category, insist on a current batch-matched certificate of analysis naming every active compound, and treat the absence of one as an answer.
Third-party testing is a claim until you have read the certificate. Ask for the one matching the batch number on your package.
Delta-8 is not simply hemp
Delta-8 THC occurs naturally in only trace amounts, so commercial product is generally made by chemically converting CBD. That process uses acids and solvents, and residual reagents or unidentified reaction byproducts can remain in the finished product.
The FDA has warned consumers about delta-8, citing adverse event reports and the fact that these products have not been evaluated for safe use, and has noted concerns about the chemical synthesis involved. Several states restrict or ban it outright.
It is intoxicating, which the marketing sometimes soft-pedals by leaning on the word hemp. Do not drive on it, and understand that dosing in edibles is delayed — the common overdose pattern is taking more before the first dose has taken effect.
THCA flower works on a similar technicality: THCA itself is not intoxicating, but heating it converts it to THC, which is the point of smoking it. Its legal status varies by state and its practical effect does not.
Cannabis and appetite work against a GLP-1
THC increases appetite. That is one of its better-documented effects and it is used clinically for exactly that purpose in some conditions.
If you are taking a GLP-1 to reduce appetite, an intoxicating cannabinoid product is pulling in the opposite direction — and edibles are themselves calorie-dense confectionery, frequently eaten in the context where restraint is lowest.
There is no evidence any cannabinoid product causes weight loss, and this site would not suggest buying one for that.
CBD specifically inhibits cytochrome P450 liver enzymes, which metabolise a long list of prescription drugs. Ask a pharmacist to check your medication list before regular use.
Drug testing and the legal picture
Delta-8, delta-9 and THCA products all produce THC metabolites, and standard workplace panels do not distinguish the source. A positive result is a positive result regardless of how the product was marketed.
State law varies substantially and changes frequently. A product legally shipped to one address is prohibited at another, and the seller's shipping restrictions are the practical guide to where a category stands.
Age 21 and over, not during pregnancy or breastfeeding, and not alongside sedatives without medical advice. Those are the baseline cautions the company itself notes.
Pros and Cons
Strengths
- States third-party lab testing and a 21-plus age restriction
- Named product categories rather than vague blends
- Notes interaction and pregnancy cautions on site
Drawbacks
- Delta-8 is typically semi-synthetic, with FDA warnings about adverse events and process byproducts
- Mushroom-edible category has a documented outbreak history including hospitalisations and deaths
- THC increases appetite, working directly against a GLP-1
- Products produce THC metabolites detectable on workplace tests
- Legal status varies by state and changes frequently
- No weight-loss relevance; not FDA-reviewed for effectiveness
Who Should Pick It — and Who Shouldn't
Good fit
An adult over 21 in a state where the specific product is legal, who has read a batch-matched certificate of analysis and checked interactions with a pharmacist.
Look elsewhere
Anyone taking a GLP-1 for appetite, anyone subject to workplace drug testing, and anyone tempted by the mushroom edible category.
Frequently Asked Questions
Is delta-8 THC safe?
It has not been evaluated for safe use, and the FDA has warned consumers about it — citing adverse event reports and concerns about the chemical conversion process used to make it, which can leave residual reagents or byproducts. It is intoxicating, and several states restrict it.
What happened with mushroom chocolate bars?
In 2024 the FDA and CDC investigated illnesses linked to one brand of microdosing chocolate bars. The CDC reported 180 cases across 34 states, 73 hospitalisations and three potentially associated deaths; testing found muscimol and, in some bars, a synthetic psychedelic. That was a different brand, but it shows the category has shipped undisclosed actives at scale.
Will these products fail a drug test?
Delta-8, delta-9 and THCA products all produce THC metabolites, and standard workplace panels do not distinguish source. Being sold as hemp does not change the test result.
Does CBD or THC help with weight loss?
No. THC increases appetite, which works directly against a GLP-1, and edibles are calorie-dense confectionery. There is no credible evidence any cannabinoid product causes weight loss.
Considering Koi?
Ask for the batch-matched certificate of analysis before buying, and check your state's position. If you are on a GLP-1 for appetite, an appetite stimulant is the wrong purchase.
