10ml (1/3 fl oz) Ultra-Potency Delta 8 Tincture 4000mg (Hemp-Derived)


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 only 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

  • This product is unflavored.
  • Bottle includes graduated dropper with 1ml capacity

    Order was processed in a timely manner with friendly customer service.

    Product is great. Can be dangerous if not careful with dose being in drops and not 1/2 mL so use caution and judgment. Taste is nonexistant to bitter with a spicy feel on the back of the throat which I am finding to be common with d8. Effects normally hit me around the 2 hr mark with a stimulating body high. Fantastic product that will be reordered. I love being able to dose drops and not mL.

    Excellent stuff. Starts working faster than others and I love the ultra concentrate!

  3. Joshua morales

    Amazing and I mean amazing product. It works extremely well. Two drops and my day is perfect. My only complaint is it’s out of stock right now because I want to order more.
    Awesome product !!

  4. Nicholas (verified owner)

    Let me start off by saying I know my tolerance and I do not recommend anyone else take the same dose as me. I was looking forward to this but sadly it never worked for me. I started with 0.5 and felt nothing. So I moved up to a whole dropper full..still nothing. By the time I was finished the bottle I was taking a dropper full plus 0.5 and didnt feel any difference. I use other delta 8 products regularly and enjoy the results with less of a dose then this. I used it all in less then a full week. This isnt to trash this product by any means this is just my experience.

    Top shelf stuff, it’s saved me a ton of cash not having to pay the ridiculous tax my state charges for D9. The effects are very similar but at a much more affordable rate.

  6. nick_placker (verified owner)

    This will knock your socks off!
    I take 20 drops and I am good to go. Completely relaxed. I take 10 drops for a more chilled out effect.
    I can find no discernable taste and I really like that it is so potent because I don’t need much.
    Highly recommended!

  7. JJ (verified owner)

    If this product were in stock more often it would be my go to for sure. Very therapeutic without all of the bad side effects that come with having to dose multiple times with less potent tinctures. Please keep this in stock more often! <3

    Harbor City Hemp has safe and effective D8 tinctures. I bought my first bottle due to the 3rd party full spectrum CoAs, their cGMP (Good Manufacturing Practices certification subjects the facility to inspections), and a Florida Dept. Agriculture Hemp Food Permit. Their ease of doing business with HCH and the owner’s passion for their business and their customers has made being a return customer a no-brainer.

    Wow! This knocked my socks off after experimenting with dosing. Started with two drops, then upped to four drops under my tounge. Didn’t really feel anything. So I decided to try 0.5 ml under the tounge and after about 4-5 hours I felt it real good. I suspect my dose will be reduced to 0.25 ml so it doesn’t hit me to heavy. This product is potent indeed!

    I have tried other brands of D8 tincture and this one works the best for me. There is little to no flavor and it doesn’t upset my stomach like the others would. Definitely will be purchasing again

  11. Blake (verified owner)

    Very good tincture. I think delta 8 tolerance shoots up much faster than delta 9 so I went through this thing super fast. Would love a larger amount than 10ml

  12. Bill (verified owner)

    Great product! I recommend this to anyone looking for a quality D8 tincture.

  13. Chris (verified owner)

    Absolutely phenomenal product. This is the best deal for Delta 8 tincture i’ve been able to find.

  14. Jon

    I have to agree with the other ‘not so great’ review on this tincture. If the 20mg per drop were true, then two hours ago I took 800mg and my tolerance is around 145 – 175mg and I feel absolutely nothing. Nada, no pain relief, no head high, no body high, absolutely nothing.

      Jon, I am very sorry to hear that you did not have a great experience with your tincture! While results and effects can definitely vary, due to a litany of factors, we stand by our product, both in potency and consistency. I have found for myself, the biggest hurdle in tincture bioavailability, which is how well the cannabinoids absorb into the bloodstream and process through the liver, is both what time of day I take it, whether I take it on an empty or full stomach, or if my indigestion is bad, and my stomach acids destroy most of the precious noids before it reaches my liver! It can definitely be a trial and error thing with edibles in general. If I take 800mg of our tincture, I can’t get out of bed for awhile! 🙂 If you would like, please reach out to me directly: [email protected] Take care!

    Apparently everyone reacts to this product differently. I did NOT heed the advice to limit the initial dose, which was a big mistake. How powerful could it be, right? I took a dropper full, and was wiped out for a day and it took another day before I was totally over it. I am now using only a drop or 2 to deal with chronic hip arthritis. Lesson learned!

  16. Martel (verified owner)

    This is a great tincture. Just find your dosage and be careful because it sneaks its powerful medicine. Package came in a timely fashion.A-1 shipping .

  17. Dino (verified owner)

    Powerful relief. Take heed of this product being ultra potency. I don’t use it daily and give myself time to enjoy the effects on the weekends. Highly recommended

  18. Lance Whisenant (verified owner)

    Great product and timely shipping! Highly recommend to anyone needing relief.

  19. Ronice Smith (verified owner)

    Finally, I have severe R/A and trying this has helped the pain, I’ve had cancer twice and this has help me to relax. Thank You so much !!! This is way better than smoking.

  20. Brandon Rhodes (verified owner)

    My wife and I enjoy two drops each, just about every day. :]

  21. Jimboh (verified owner)

    Great tincture! If you have not used this high potency before, be advised to go slowly. I’m used to it, and usually start off with 4 drops to relax. It’s very strong, and helps me to sleep soundly every night that I take it.

  22. SM (verified owner)

    This is an outstanding tincture from an amazing company. I firmly believe that this product is unrivaled by anything else on the market. Keep up the great work, Harbor City Hemp!

    Nobody here is really stretching the truth when they’re saying this stuff is strong. One thing to keep in mind as always with Delta-8 is that it’s a very different high from Delta-9, but it’s nonetheless very pleasant and relaxing. However, this was probably the strongest high I’ve had yet under 8, so this is worth a shot. It’s also somewhat of a different high from Delta-8 vapes or edibles, but the convenience of this means of ingestion is definitely something to consider. I just sometimes found myself being significantly more under its effects than I’d realized when compared to edibles or vaping, so be cautious not to overdo it.

    I’m honestly impressed with the folks that say they can casually drop this stuff in their coffee and get along perfectly with their day, but more power to them because this will take the edge off of everything. I got quite a lot of use out of the 4000mg bottle here, so the price point is definitely a fair one. Whether you’re looking for a way to take the edge off without too much visibility, vapes trigger your asthma or you’re just not a fan, or maybe you’re just looking to experiment beyond vapes or edibles, this is nice to have even if it doesn’t turn out to be your favorite method. Great to keep in the medicine cabinet, one drop under the tongue is all you need to calm down in case of emergency.
