I’m looking for the formula to mix distillate with MCT oil to dose 10mg THC capsules.
What’s the starting tcc% of the distillate.
Heres an example.
Say you have a 90% tcc distillate. If you make 10 edibles (evenly), you’ll have 10x 90mg edibles.
A week or so ago, this was asked, and I gave pretty much the same answer. A quick hit and words typed into that magical search icon would pull up a vast assortment of clues, tips, and answers.

Take a shot stating which variables are necessary for this calculation and I’ll write out/explain the equation to calculate what you need

You will need a potency on your distillate to figure that out…
Eg: if you’ve got 83% THC, there are 830mg of THC in every gram of distillate. So you could make 83 of your 10mg caps.
If you’re dealing with 92% distillate, then you can make 92, because 0.92 x 1000mg/g == 920mg THC per gram of distillate.
How much MCT?
That’s up to you!
Either determine how much fits in a capsule. Or decide how much you’re going to put in there. A 1ml syringe will probably help you figure out this number, and might help you get the same amount in each cap if you chose not to just fill the larger “half”.
Let’s imagine you decide that your 00 caps should have 0.2ml in them.
So how much MCT for those 92 or 83 caps?
Don’t forget to adjust for the gram of distillate you used. You can look up the density of crude around here, or take my word for it that the number is close enough to 1g/ml (1kg/liter) that most approximate it thusly.
Got everything you need?
Or are you going to have to guess at the potency of your input material?
If you guess 95%, and you were sold 82%, what are your customers going to get for dosage?
How about if you guess 82% and received 95%?
Wrapping your head around that math should help you understand the problem, and help inform your guesstimate should you be going that route…

OP is looking for formula.
Your spoon is not needed here…

Ah ok. I was just saying the spoon you gave him was a whopper. Didn’t mean to upset anyone.

I have 86% THC distillate. Capsules will hold 400mg of liquid. Im trying to make 10mg THC in each capsule. Im thinking the math for 1 capsule. Is 11.65mg of the distillate and 388.37mg of mct oil.
So im thinking for 1000 capsules at 10mg. I would need 12grams of distillate and 388 grams of mct oil

I dont know how to check my numbers but this is what I came up with. 86%THC distillate. Capsules hold 400mg of liquid. Im thinking for 1000 capsules ill need 12 grams distillate and 388 grams mct oil. Hoping this works out to 1000 capsules at 10mg each
how you check your work depends on how you did your math.
which you didn’t show.
but lets take a look anyway.
12grams of distillate == 12,000 mg.
x 0.86 => 10320mg of THC
which will give 1000 caps at 10.32mg.
which is close to your target, but you could do better.
you want a total of 10,000 mg THC in your 1000 caps
10,000mg THC / 0.86 => 11,627 mg. you could round that to 12g, but 11.6g would a be better approximation.
0.4g is a significant chunk of 12g (3% as shown by the 10.3mg vs error 10mg earlier)
also wondering about that 400mg/cap. how did you generate that number?
did you use a scale? or should those units be ml?
edit: sorry. then saw your answer to @SidViscous

that will depend on the density of the liquid.
how much MCT do they hold?

Good starting point but you definitely want to do your own pack stats based on filler and active ingredient. Microcrystalline vs Lactose for example pack a lot different.

No doubt. But if you know the powder (or liquid) density, you should be able to calculate everything.
| Size | 000 | 00 | 0 | 1 | 2 | 3 | 4 |

| 2. Capacity | |||||||
| Volume in ml | 1.37 | 0.91 | 0.68 | 0.50 | 0.37 | 0.30 | 0.21 |
| Powder Density - Capsule capacity mg | |||||||
| 0.6 g/ml | 822 | 546 | 408 | 300 | 222 | 180 | 126 |
| 0.8 g/ml | 1096 | 728 | 544 | 400 | 296 | 240 | 168 |
| 1 g/ml | 1370 | 910 | 680 | 500 | 370 | 300 | 210 |
| 1.2 g/ml | 1644 | 1092 | 816 | 600 | 444 | 360 | 252 |
Here is a tool I’ve used to better understand the tincture creation process, for this example we can think of a capsule as essentially just a tiny tincture.
Spreadsheet is attached Blending.Tool.xlsx (11.6 KB)
Some notes for reference / usability
This is a batch constrained perspective, what that means is that you first need to decide how many units you want to make. For this example we will make 2000 capsules of size 0, these hold .68ml, those values are then entered into cells C2 and C3.
The second step is to enter the potency/concentration values from your COA into cells D9:D13, D14 will calculate organic matter automatically based on these values (F4).
The 3rd step is to use the tool to fine-tune how many grams of distillate you need, this is done using F2 to tune the values in J9-J14, which is your end-game desired potency of 10mg. The amount/grams of MCT you need to add to this distillate in provided in cell C17.
There are a few assumptions in this tool - it does not account for transfer losses and assumes that no distillate will be absorbed into the MCT volume. Essentially, the total batch volume is additive.
We also assume a resulting homogeneous mixture and I would recommend heating both your MCT and distillate to 150f and then mixing for 1 hour over low heat before filling the capsules.
@Jc715 Hope this helps, open to any ideas or insights from @cyclopath or anyone else interested in dilution blending.

Thanks for sharing! I modified it a bit to be able to adjust for density of the distillate since I’m often using stuff that’s already been homogenized in some MCT. It’s a handy tool.
