4 Corners Cannabis review: oils, ingredients and testing evidence

Compare 4 Corners Cannabis oils, gummies and topicals, with exact-variant pricing, historical lab reports and separately assessed customer feedback.

Updated October 29, 2026

4 Corners Cannabis offers its 1,000 mg oils with either coconut-based MCT or avocado oil. Both bottles have the same labeled CBD concentration and had the same price when checked. The choice comes down to the carrier oil and flavor you prefer.¹²

The nine products in CBD Diff's catalog include human and pet tinctures, three gummy flavors and two topicals. This review covers those records and selected public sources checked on October 29, 2026. We did not purchase or personally test the products.

Two oils with different ingredient lists

The Original CBD Tincture, sold as Coconut Citrus Oral Tincture on the official site, lists MCT oil, hemp extract and limonene from orange extract. The Avocado Oil CBD Tincture lists virgin organic avocado oil and hemp extract. Its ingredient list has no added coconut or citrus, although that does not establish freedom from cross-contamination.¹²

Both 1,000 mg/30 mL bottles contain a labeled 33.3 mg CBD per mL:

Oil	Labeled CBD	Volume	Calculated CBD per mL	One-time price, USD	Calculated USD per mg CBD
Original / Coconut Citrus	1,000 mg	30 mL	33.3 mg	$59.99	$0.060
Avocado	1,000 mg	30 mL	33.3 mg	$59.99	$0.060

These were the selected variants' displayed prices on October 29, excluding shipping and taxes. Subscription offers were separate. The lower $17.49 starting price on both pages belongs to a 250 mg/15 mL bottle; applying it to the 1,000 mg bottle would understate its cost.¹²

All nine catalog records are classified as full spectrum. The manufacturer uses “complete spectrum” in its ingredient descriptions. Neither term establishes a batch's precise THC content or a zero-THC guarantee. The catalog selection also does not represent everything the company sells.

Gummies and topicals

The three gummy flavors are Elderberry Reishi, Lemon Ginger and Mango Goldenberry. Each lists 25 mg CBD per gummy and 20 servings, giving 500 mg per package. All three include honey, so their listed recipes are unsuitable for someone seeking vegan gummies. Flavor names and the presence of reishi or ginger do not establish additional health benefits.³⁴⁵

Elderberry Reishi CBD Gummies and Mango Goldenberry were both marked “Out of stock” on their official pages during the check. Their presence in the catalog does not confirm availability. We did not verify live availability for Lemon Ginger.³⁵

Original CBD Salve uses a coconut oil and beeswax base and is described as menthol-free. CBD Diff tracks its 250 mg/1 oz option. The lotion record is 500 mg/2 oz, with a longer ingredient list that includes aloe vera juice, coconut oil and glycerin. These are different topical formulations; doubling the package's CBD number does not by itself establish better performance.⁶⁷

The topical specifications came from older retrieved official-page copies. Check the current container's ingredients and size before relying on them.

Comparing the pet formulas

The two pet tinctures use golden hemp seed oil. One lists hemp extract without an added flavor; the other adds organic peanut butter flavor and describes its extract as animal grade. Our catalog tracks 1,000 mg/30 mL for both. Those labels do not make pet and human formulas interchangeable or establish suitability for an individual animal.⁸⁹

A Dogster writer tried both pet formulas and reported that the dogs disliked them on their own but accepted them with food. Peanut butter flavor did not guarantee acceptance in that household. The article discloses supplied products and affiliate commissions, and we could not match the reviewed bottles to our catalog's strength or batch. These taste observations do not establish effectiveness.¹⁰

What the published lab reports show

The official testing index links reports by product and batch. We inspected four documents covering three samples or batches: Original tincture potency, Avocado tincture potency, and Elderberry Reishi gummy potency and pesticides. The report dates span 2019 to 2022.¹¹

The Original report, dated March 2, 2020, lists 1,027.36 mg CBD per 30 mL unit for batch 4_100003. The Elderberry Reishi potency report, dated April 5, 2022, lists 26.90 mg CBD per gummy for batch 55_101, compared with the product's 25 mg label. A separate report for that gummy batch lists passing results for its 13 tested pesticides. These observations apply to the tested samples and panels.¹²¹³¹⁴

The Avocado report needs clarification. Dated June 12, 2019, it lists delta-9 THC as 27.91 mg per unit and 1.01%, while marking THC content “Pass.” We could not reconcile those entries with each other and the current product page's less-than-0.3% THC claim. Both linked copies showed the same entries. This is an unresolved historical document discrepancy, not a finding about the contents or legality of current stock.²¹⁵

These manufacturer-hosted reports were not authenticated with the laboratory or matched to bottles currently shipping. For a purchase decision, ask for a report matching the batch on the bottle; the older results cannot establish its composition.

Product ratings and company feedback

CBD Diff's validated October 29, 2026 snapshot contains three published ratings across three of the nine products: the two pet tinctures and Mango Goldenberry gummies. Their review-count-weighted average is 4.3/5. That small product-rating sample is not a separately submitted brand score, and the numbers alone do not explain buyers' experiences.

The live Trustpilot profile displayed a TrustScore of 4.9/5 from 1,088 reviews on October 29, 2026. It also showed only one review in the preceding 12 months. This is a company profile, separate from CBD Diff product ratings.¹⁶

We inspected the 20 most recent entries, published from July 2022 through December 2025: 13 had body text and seven were title-only. Several described prompt delivery, while one March 2023 reviewer reported an undelivered order and a promised resend. No resolution was visible for that complaint. The sample was mostly old, included off-topic entries, and rarely identified an exact product variant. It supports a limited account of service experiences, not a current product-quality score.¹⁶

Our verdict

4 Corners Cannabis is worth comparing if you have a preference for a particular carrier oil or topical recipe. Its verified 1,000 mg oil offers let you choose between carriers at the same concentration and price. For gummies, honey and availability may narrow the choice before flavor does.

The older testing documents and sparse recent feedback leave questions about current batches. Resolve any inconsistent entries in a matching report before relying on it.
