How to Infuse MCT Oil with a tCheck

On a keto diet? That doesn't mean you can't enjoy infused treats! MCT oil, or medium-chain triglyceride oil, is a dietary supplement made from medium-length chains of fats called triglycerides. It is easily digested and converted into energy, making it a great choice for those following a keto (ketogenic) diet. Want to get high from your favorite low-carb meals?

⚗️ How to Infuse MCT Oil with THC

Before getting into the steps, here is why MCT oil is the preferred carrier for cannabis infusions.

🧬 What Is MCT Oil and Why Is It Ideal for Cannabis?

MCT stands for medium-chain triglycerides — a type of fatty acid derived primarily from coconut oil or palm kernel oil. Unlike long-chain fats found in most oils, MCTs are rapidly absorbed by the body and converted directly into energy by the liver, which is why they're popular in ketogenic diets.

For cannabis infusions, MCT oil offers two key advantages: it's completely flavorless (unlike coconut or olive oil), and its rapid absorption may make the effects of your infusion feel more pronounced. It also has a longer shelf life than many carrier oils and stays liquid at all temperatures, making it easy to measure into capsules or add to beverages without any measuring guesswork.

🌡️ MCT Oil Infusion Temperature Guide

Temperature control is critical for MCT oil infusions. Too hot and you'll degrade THC into CBN (which causes drowsiness rather than the experience most users want). Too cool and your extraction will be incomplete.

• 160°F (71°C): Minimum effective temperature. Slow extraction — works but takes longer.
• 170°F (77°C): Optimal sweet spot. Efficient extraction with minimal cannabinoid degradation. Aim for this.
• 180°F (82°C): Upper limit. Brief spikes to this temperature are acceptable, but sustained temps will start degrading terpenes and THC.
• Above 200°F (93°C): Avoid. Significant THC degradation and terpene loss.

Use a kitchen thermometer or slow cooker with a temperature setting rather than guessing. After infusing, confirm your final potency with the tCheck cannabis testing device — it gives you exact mg/mL in about 2 minutes, so you know precisely how many milligrams are in each dose.

🥥 MCT Oil vs. Coconut Oil for Cannabis Infusions

MCT oil and coconut oil are closely related — MCT oil is actually refined from coconut oil. But they behave very differently in infusions and in your body. Coconut oil is about 54% MCTs by composition, while pure MCT oil is 100% medium-chain fats. This makes MCT oil significantly more bioavailable and faster-acting.

If you prefer the neutral taste of coconut oil but want faster absorption, MCT oil is the better choice. For capsules, tinctures, or adding to coffee and smoothies, MCT oil is almost always the superior option.

What You'll Need

• 1 cup of MCT oil (you can get this from GNC, Walgreens, Amazon, or wholesale retail)
• 1/4 ounce of dried herbs or plant material of your choice (such as cannabis, lavender, or rosemary)
• A slow cooker
• Cheesecloth or mesh strainer
• A tCheck device

Step 1: Decarboxylate your cannabis

To activate the THC in your cannabis, it needs to be decarboxylated. If you're new to the infusing world, no worries — we've explained decarboxylation too.

To properly decarboxylate your weed, preheat your oven to 240°F and place your cannabis on a baking sheet. Bake for 30–40 minutes. This will convert THCa into THC, the main psychoactive compound that'll make you feel lifted and fuzzy.

Step 2: Infusing with Cannabis

In a slow cooker, combine 1 cup of MCT oil with 1/4 ounce of your newly decarbed cannabis. Set the slow cooker to low heat and let the mixture infuse for 4–6 hours, stirring occasionally. Be sure to keep the temperature below 200°F, as higher temperatures can degrade the cannabinoids.

Step 3: Strain the infused oil

Once the infusion is complete, let it cool and strain out the cannabis pulp. You can use a cheesecloth or fine-mesh strainer to ensure that all the cannabis pulp is removed.

Step 4: Test the potency with the tCheck home potency tester

Using a dropper, transfer a small amount of the infused oil into the tCheck syringe. Place a filter on the syringe and put 3–5 drops into your reusable tray. Insert the tray into your tCheck potency analyzer and follow the on-device prompts. If the potency is too low, you can add more cannabis to the infusion and repeat the process. If the potency is too high, you can dilute with more MCT oil.

Final Thoughts

Infusing MCT oil with cannabis is a simple and effective way to create versatile, low-carb cannabis products that fit perfectly into a keto lifestyle. By following the right steps — especially proper decarboxylation, controlled heat during infusion, and careful straining — you can achieve a clean and potent final product ready to use in a variety of recipes.

However, the most important step is knowing your potency. Without testing, it's easy to underdose or overdo it. That's where tCheck comes in, giving you accurate, real-time insights into your infusion so you can adjust as needed. With the right process and reliable testing, you can confidently create consistent, safe, and perfectly balanced cannabis-infused MCT oil every time.

Frequently Asked Questions

Why is MCT oil ideal for cannabis infusions?

MCT oil is rich in medium-chain triglycerides that bind readily to cannabinoids. It has a neutral flavor that won't overpower recipes and a long shelf life.

What temperature should I infuse MCT oil with cannabis?

Keep the temperature between 160–180°F. This range extracts cannabinoids effectively without degrading THC or terpenes.

How long does cannabis MCT oil stay potent?

Stored in a cool, dark place in a sealed container, cannabis MCT oil typically remains potent for 6–12 months.

Can I use cannabis MCT oil for sublingual dosing?

Yes. MCT oil tinctures work well sublingually, with effects typically appearing within 15–45 minutes — faster than traditional edibles.

How do I measure the THC content in my MCT cannabis oil?

Use the tCheck Potency Tester for an accurate mg/mL reading of any MCT oil infusion in about 2 minutes.
