RSO Capsules: How to Make and Dose Them at Home

Ask our regulars who’ve been on RSO for a while how they take it, and a surprising number say the same thing: capsules. They got tired of the taste, tired of guessing at a rice grain in the kitchen light, and tired of nights that didn’t match. So they spent twenty minutes one Sunday filling capsules, and they never went back.

Here’s how to do that, including the parts that usually go wrong the first time.

Why RSO capsules are worth the effort

RSO has two real problems for daily use. It tastes like exactly what it is, and it’s nearly impossible to measure precisely from a syringe. A capsule solves both. Once a batch is made, every capsule holds the same amount, there’s nothing to taste, and taking one is as simple as taking a vitamin.

The trade-off is a bit of setup and the same slow onset as any edible. If you need relief within the hour, this isn’t the route. If you want a predictable nightly dose, it’s the best one.

What you need

• Your RSO syringe, with its lab result so you know the THC percentage.
• Empty gel capsules, size 00 or 0. A bag of a few hundred costs very little at any pharmacy or online.
• A small bottle of MCT oil or coconut oil.
• A capsule filling tray, optional but worth it. The cheap plastic kind that holds 24 capsules upright is plenty.
• A dropper or a small syringe for filling.
• A jar, a label, and a marker.

Do the math first

Grams times THC percentage times 1,000 is the total milligrams in your syringe. A 0.5 g syringe at 70% holds about 350 mg. A full gram at 70% holds about 700 mg.

Decide the dose per capsule before you touch anything. If you’re new to RSO, 10 to 15 mg is a sensible capsule. Regulars often make 25 mg capsules and take one or two. Divide the total by the dose to get the capsule count. That 350 mg syringe makes about 24 capsules at 15 mg each.

Write those numbers down now. You’ll want them on the label.

Making the batch

Warm the syringe. Ten minutes in a cup of warm tap water. Cold RSO won’t flow.

Thin it. Squeeze the whole dose you’re using into a small glass, then add MCT oil. For 24 capsules, two tablespoons of MCT is about right; it gives you enough volume to fill each capsule to a consistent line. Stir with a toothpick until the color is completely even, no dark streaks. This step is the difference between a batch where every capsule matches and a batch where one is a monster.

Fill. Stand the capsule bottoms in the tray. Use the dropper to fill each to the same level. Go slowly; the oil is thicker than water even after thinning. Cap each one and give it a gentle twist to seal.

Wipe and label. Wipe the outsides so they don’t stick together. Into the jar they go, with a label that says the milligrams per capsule and the date.

The whole thing takes about twenty minutes once you’ve done it once.

Taking them

One capsule, with a small snack that has some fat in it, about 90 minutes before you want the effect. Then wait. Two hours, not one. Swallowed RSO arrives slowly and lands hard if you double up early.

Hold the same dose for four or five nights before changing anything. If you want more, take a capsule and a half, or make the next batch stronger. Write down how each night went. Two weeks of notes will tell you more than any guide.

Mistakes that waste oil

Filling straight from the syringe without thinning. The doses vary a lot, and the first capsule usually gets half the batch.

Heating the oil too hard to thin it. Warm water, not a microwave, not a pan. Scorched RSO is weaker RSO.

Making capsules too strong to start. A 50 mg capsule sounds efficient until you take one on a Tuesday. Make a modest batch first and adjust.

Storing them warm. Gel capsules soften and stick, and heat fades the oil. Fridge, in a labeled jar, away from anyone who shouldn’t have them.

When capsules aren’t the answer

If you want RSO to work faster, hold it under the tongue instead. If you’re using it for a sore knee, a topical is the better route. And if you’d rather skip the whole project, we carry pre-made capsules and tinctures from local producers with the dose printed on the box. Ask at the counter and we’ll show you what’s in stock.
