30ml (1 fl oz) Ultra-Potency Delta 8 Tincture 12000mg (Hemp-Derived)


One of our most popular products is now available in a new larger size! Our Ultra-Potency Delta 8 tincture was made for those with very high delta-8-THC (D8) tolerances that want to take higher doses of D8 tincture without having to ingest a large amount of MCT oil (too much can cause an upset stomach). This product is extremely potent at 400mg/ml, so only a small amount is needed compared to our 1500mg Delta 8 tincture that has a concentration of 50mg/ml.

Each batch of our D8 tincture is tested for cannabinoid potency and the source distillate used is additionally tested for heavy metals, residual solvents, and pesticides. All product and source cannabinoid COAs can be found here.


  • Serving size: 1 drop (~20mg delta-8-THC)
  • Total delta-8-THC concentration of 12000mg (400mg/ml)
  • Suggested use: Take 1 serving as needed, or as directed by your healthcare provider. It may take several hours for full effect and can vary from person to person. The required amount for full effect can also vary greatly between individuals
  • Ingredients: Organic MCT Oil, Hemp Extract
  • Contains: Tree nuts (coconut)
  • This product is unflavored.
  • Bottle includes graduated dropper with 1ml capacity
  • This product contains a total delta-9-THC concentration that does not exceed 0.3% on a dry weight basis.
  • Warning: As this product contains federally legal hemp-derived delta-8-THC, an isomer of THC, it may cause a positive result on a drug test.
  • Store in a cool dry place away from heat and light. Keep away from children.
  • In order to provide a safe and high quality product, all of our products are produced in a FDACS licensed commercial processing facility that receives periodic inspections and is cGMP compliant. As an additional measure of safety, ethanol is the only solvent used in the entire process from hemp plant to our delta-8-THC tinctures.

    This is basically like the 4000 mg one except a 30 ml container .I would have to say really sets in around the 3rd and 4th hour after doing recommend dosage .please be careful because doing to much can cause a slight stomach ache.I suffer from a twisted pelvic and nerve damage to my neck and lower back and it seems as if it’s not there .I can’t remember the last time I said my body hurt and I’ve only tried this for 2 weeks now . I found this site upon research and was skeptical since all of us react differently ,but nope it’s worth the price, every penny. I will be purchasing again .was not disappointed with it being my first time trying this brand .

    Stunning product. I have an extremely high tolerance and this product does not require a lot of substance to get the desired effect. Approach it with respect and you will be amazed at the physical and mental effects.

    A “high tolerance” doesn’t help the new consumer lol I need numbers. Here’s my numbers review. I’m 5′ 8″ about 215. I used to smoke 20%s flower but ive stopped for a month now. I was also smoking a gram or 2 of dabs a day. Its also been a month now. A good time for me right now in D8 is about 150-200mgs. From the 12k bottle I took 5 20mg drops under tongue waited 30 seconds and put 5 20mg drops in cold milk. Consumed both at same time. Waited 2 hours and it got a great body h**h and it numbed me, eased all pains. Its still going 4-5 hours later but it’s finishing. Its good stuff and intense but its not a spacey, D9 high. Its like 80% of a good rip high. I don’t take opiates now but I did in the past. I would compare it to a 10perc to someone that takes 5mg norcos. I add the pain reference because most are here for pain issues. That being said, don’t take this review light. Dose yourself right. With 10 drops to me is very pleasant and I’m satisfied. I want to give it even more but I realize that a drop or 2 more might have been a bad thing. The other reviewers arent lying though, be careful. I feel it is worth the value that I spent. It arrived in the mail just fine. It does address my “tolerance” with force but I don’t feel like I over did it. I will buy again. If you’re new this is not the option you want, you will have a bad day. Also keep in mind with oral consumption body weight, liquid intake, consistency of liquid, metabolism speed, age etc. also plays a huge factor on the effectiveness of this product. It is strong. I hope this helps!

    Strongest dose of Δ8 I have ever had, it’s freaking amazing for anxiety disorder. In the past I vaped many carts, made so many edibles with disty, and a few drops of this blows all that out of the water. NOT for amateurs, but perfect for frequent fliers like myself.
