Rick Simpson Oil, better known as RSO, has become one of the most talked-about cannabis products for people who want something stronger, longer-lasting, and more full-spectrum than a standard edible or THC tincture.
RSO is usually thick, dark, and highly concentrated. It contains THC along with other cannabinoids, terpenes, and plant compounds, which is why many people reach for it when they want a more complete cannabis product.
You’ll find it in syringes, gummies, capsules, tinctures, and other formats, depending on the company and the state you’re in.
The challenge is that not every RSO product works the same way. Some products give you strong high-THC dosing. Others focus on convenience, flavor, medical access, or smaller serving sizes.
If you’re comparing your options in 2026, it helps to look at potency, format, ease of use, and who the product actually makes sense for.
Below are five RSO products worth knowing about, with RickSimpsonOil.com ranked first for its direct focus on authentic, high-THC RSO products.

RickSimpsonOil.com
Product Type: RSO gummies
Potency: 50mg THC per gummy, with other cannabinoids from real RSO
Pros: Strong dose, multiple flavors, sugar-free options, bulk options, and no bitter raw RSO taste
Cons: Too strong for low-tolerance users if you start with a full gummy
Best For: You want potent RSO in an easy edible format
RickSimpsonOil.com takes the top spot because its RSO gummies are built around the core reason people look for RSO in the first place: potency. Each gummy contains 50mg of THC, which is much stronger than many dispensary edibles that sit around 5mg to 10mg per piece.
That higher dose makes RickSimpsonOil.com a better fit for people who already understand THC or need a stronger cannabis edible. These gummies aren’t the kind of product you casually take without thinking. You need to dose carefully, especially if you’re newer to RSO.
RickSimpsonOil.com offers a strong edible format without the bitter taste or sticky texture of raw RSO oil. The gummies come in 12 or more flavors, and you can find sugar-free and bulk options. That gives you more flexibility than a single syringe or one-flavor gummy.
Grassroots
Product Type: Full Spectrum RSO syringe
Potency: Often around 70% or higher THC, depending on the batch and dispensary listing
Pros: Strong, versatile, full-spectrum, and easier to measure than loose oil
Cons: Availability depends on your state, your dispensary, and the current batch
Best For: You want traditional full-spectrum RSO and you’re comfortable measuring small amounts from a syringe
Grassroots is a well-known cannabis company with full-spectrum RSO syringes sold through dispensaries in several markets. Grassroots RSO is closer to the classic RSO experience because it comes in a syringe and gives you more direct control over the amount you use.
Many Grassroots RSO listings show THC percentages in the 70% range, with small amounts of other cannabinoids like CBD, CBG, or CBN depending on the batch. That’s important because RSO buyers usually want more than isolated THC. They want a product that keeps more of the plant’s original profile.
Grassroots RSO is strong, versatile, and familiar to people who already use cannabis concentrates. You can take it orally, use it sublingually, or add it to food. The syringe format also lets you adjust the serving size more carefully than a pre-made edible.
Encore Edibles
Product Type: RSO gummies
Potency: 100mg THC per 10-pack, with 10mg THC per gummy
Pros: Lower-dose edible, familiar gummy format, easier starting point, and fruit flavor
Cons: Less potent per piece than many RSO products
Best For: You want to try RSO in a familiar edible format without starting at a heavy dose
Encore Edibles offers RSO gummies in a more approachable format. The Concord Grape RSO Indica Gummies are one of the better-known options, with 10 gummies per pack and 100mg THC total. That gives you 10mg THC per gummy.
This product works well if you’re interested in RSO but don’t want to jump straight into a 50mg edible or a high-potency syringe. Encore Edibles keeps the experience simple. You take one gummy, wait for the effects, and adjust from there.
Encore Edibles gives you a lower-dose RSO gummy that’s easier to work into a normal edible routine. The pectin-based texture and fruit flavor also make it more pleasant than raw oil.
Dr. Solomon’s
Product Type: THC Rich RSO syringe
Potency: 1g full-spectrum RSO syringe, with potency varying by batch
Pros: Medical-focused, flexible use, full-plant extract, and strong dose control
Cons: Can be intense for beginners and may not be available in every market
Best For: You want a medical-style RSO product and prefer a syringe over a gummy
Dr. Solomon’s leans into the medical side of cannabis. Its RSO products use full-plant extract and are positioned for people who want potent, flexible relief. The company’s RSO can be swallowed, held under the tongue, mixed with food, or applied topically, depending on your needs and guidance from a cannabis professional.
The THC Rich RSO format is best suited for experienced cannabis users or medical cannabis patients who need something stronger than gummies or tinctures. Because it’s concentrated, even a small amount can feel powerful.
Dr. Solomon’s gives you a serious RSO option with flexible use. The syringe format helps with careful dosing, and the full-spectrum profile appeals to people who want cannabinoids, terpenes, and other plant compounds in the same product.
Texas Original
Product Type: RSO oral syringe
Potency: 410 to 412mg THC per 0.5g syringe, with 8mg THC per 0.01mL
Pros: Medical-grade, full-spectrum, precise dosing, and simple ingredient profile
Cons: Restricted to qualified Texas medical cannabis patients
Best For: You’re a qualified Texas patient and want a regulated full-spectrum RSO syringe with clear dosing
Texas Original’s RSO Oral Syringe stands out because it serves medical cannabis patients in Texas, where access works differently than in many adult-use states. Its 0:1 RSO Indica 0.5g syringe contains about 410 to 412mg THC per syringe and uses full-spectrum cannabis extract.
Texas Original also makes the product with one ingredient: full-spectrum cannabis extract. That clean formulation may appeal to you if you want to avoid added dyes, flavors, sugar, or unnecessary ingredients.
Texas Original offers precise, medical-grade dosing in a regulated program. The smaller 0.5g size may also feel more manageable than a full 1g syringe for patients who need careful control.
How To Choose the Right RSO Product
The best RSO product depends on your tolerance, goals, and preferred format. If you want strong edible dosing and more flavor options, RickSimpsonOil.com is the best overall pick. If you want a classic syringe, Grassroots and Dr. Solomon’s both make sense.
Encore Edibles is better if you want a lighter starting point. Texas Original is the better fit if you’re in Texas and need a medical cannabis product through a regulated program.
You should also pay attention to local laws. RSO products with THC are not treated the same in every state. Some products require a medical card, some must be purchased through licensed dispensaries, and some may not be legal where you live.
Start low, go slow, and give RSO time to work. Edible and oral RSO products can take a while to kick in, and the effects can last longer than smoking or vaping cannabis.
