I cap all my orals, but I suppose if your scale will read that low its possible to just swallow the powder. I think capping would be more convenient, though.

Nope, you can just swallow it. If you got a scale that measures that accurately and you dont mind weighing out multiple doses daily, go for it. But unless you have a lot of time on your hands, capping or an oral solution is a lot less time consuming.

You do need a very accurate Scale.
I have a cpping powders articles somewhere.. I'll see if I can find it

first.. you will have to rework the numbers of course
but you get the idea
from SV-1.
Although there are easier methods out there when it comes to capping orals they produce results that are somewhat less than accurate. I (SV-1) decided to write this article to show you step by step how to produce caps with a high level of accuracy. Credit goes to AnabolicMaster, ColdStone and Lozgod who helped make this possible.
Things you will need to make your caps.
1. A capping device and empty gel caps. The two most popular capping devices are the "Cap-M-Quick" and "The Capsule Machine". The cap-m-quick does 50 caps at a time but you have to manually join the caps by hand. The capsule machine only does 24 caps at a time but automatically joins them for you. Both of these devices can be purchased to use either size "0" or "00" caps (size "0" caps are smaller than size "00"). I prefer the capsule machine and size "0" caps, but either device in either size is fine.
2. A scale to weigh the powders you'll be using to make your caps. I recommend either the Palmscale 5.0 which is accurate to 0.1g and has a capacity of 200g (cost approx $60), or the GemPro-50 which is accurate to 0.002g and has a capacity of 10g (cost approx $150).
3. The powdered version of the compound that you plan on capping. Oral compounds such as Anavar, DNP, Clomid, Dbol, Nolva and Winny make good capping choices. However compounds such as Clen, T3, Femara and Arimidex should never be capped because of their small dose amounts and the inherent inaccuracies of the capping process.
4. A powdered filler that will be used to take up the space in the caps that the active compound doesn't. Almost anything can be used as a filler, Protein Powder, Baking Soda (Sodium Bicarbonate), Corn Starch, Flour, Creatine, Lactose, Glutamine, etc.
5. A mortar and pestle to thoroughly mix the active compound and filler together. Many compounding pharmacies use a mortar and pestle to mix their ingredients together for capping and if it's good enough for them it's good enough for me.
Now that we have everything necessary to make our caps here's how we do it. For the example below I'll use the capsule machine to make 48 caps with 100mg of Aspirin (active compound) and Baking Soda (filler).
1. Load 24 empty caps into the capsule machine, then fill all 24 caps with Baking Soda (tamping powder if final caps will be tamped).
2. Empty all the Baking Soda out of the capsule machine and weigh it. Total weight = 17,160mg
3. Divide that weight (17,160mg) by the number of capsules (24) to get the total weight per cap. 17,160mg / 24 = 715mg a cap.
4. Repeat these steps with the Aspirin powder. Total weight = 11,760mg / 24 = 490mg a cap.
5. Now we need to figure out the ratio of Aspirin to Baking Soda.
100mg Aspirin = Unknown mg of Baking Soda
490mg Aspirin = 715mg Baking Soda
(100mg Aspirin x 715mg Baking Soda) / 490mg Aspirin = 146mg of Baking Soda (this is the Unknown mg of Baking Soda, and how much must be removed to make space for 100mg of Aspirin)
715mg Baking Soda - 146mg = 569mg Baking Soda (this is how much Baking Soda to use per cap)
569mg Baking Soda x 48 caps = 27,312mg Baking Soda
100mg Aspirin x 48 caps = 4800mg Aspirin
So to make 48 100mg Aspirin caps we need 4800mg of Aspirin powder and 27,312mg of Baking Soda.
This is where the simpler methods fail and give inaccurate results. Different compounds (like Aspirin and Baking Soda (Sodium Bicarbonate)) weigh different amounts for the same volume. If we had simply subtracted 100mg from the Baking Soda we would not have had properly dosed caps, because to fit in 100mg of Aspirin we needed to subtract 146mg of Baking Soda.
Now that we know how much active compound and filler to use (Aspirin and Baking Soda) we need to mix them together. To do this we'll use a mortar and pestle with the geometric dilution method, which was introduced to me by pharmguy24 on AU. What's the geometric dilution method you ask? It's a method used when a small amount of powder needs to be *thoroughly* mixed with a larger amount of powder. To do this you mix all of the smaller powder with an approximately equal amount of the larger powder, this blend is called "mix 1". Then combine all of your "mix 1" with an equal amount of the larger powder and blend again, this is "mix 2". Keep going like this until all the powders have been mixed together.
So we place all of the Aspirin powder (the smaller amount of the two different powders) in the mortar and add an equal amount of the Baking Soda (approximately 4800mg), then blend them together with the pestle for a couple of minutes. This combination is our mix 1, and it is now 9600mg (4800mg Aspirin + 4800mg Baking Soda). After it's been blended for a few minutes add an equal amount of Baking Soda (9800mg) to your mix 1 and blend for a couple more minutes. This combination is our mix 2 and is 19,200mg (9800mg from mix 1 + 9800mg Baking Soda). After it's been blended for a few minutes add the remaining Baking Soda (12912mg) to your mix 2 and blend for a couple more minutes.
Why go to this extra trouble? Because even though we know the amounts of Aspirin and Baking Soda we're using are dead on, our caps will not be dosed properly if the powders are not mixed together very thoroughly.
Now we're ready to make our caps.
1. Load both the base and top of the capsule machine with the empty gel caps (the bottom should already be loaded from weighing the powder for mixing).
2. Place the base on its stand and pour the mixed powder over the empty caps, then spread it around using the supplied plastic card so all the caps are filled.
2a. Optional: At this point you can tamp the powder down and add more powder to the caps increasing the amount they can hold. But because what we want to cap fits fine without doing that we didn't calculate for it and wont be doing it.
3. Attach the top of the capsule machine (which contains the other halves of the caps) to the base.
4. Remove the capsule machine from its stand and press it down on your work surface applying even pressure to join the caps.
5. Remove the top from the capsule machine and press against the spring loaded plate on its back to eject the finished caps.
6. Repeat these steps until all your caps are made.
Follow these guidelines and you too can make your own accurately dosed caps.

Capping 101
From Lozgod At AnabolicReview Forums
This thread will give a simple version of capping along with a method for the more mathmatically inclined. Credit goes to Coldstone, SV-1, and Anabolic Master for the information. Official sticky info compiled in to one nice package by Lozgod.
Simple Version by Coldstone:
Capping is very easy...first you need to get a capping machine...Mr T has one that is very nice...just do a search for caps...i get 1000 for like 9.99 or something like that...00 size is the way to go also...
I myself and sv-1 i know prefer the "capping machine"...it only does 24 at a time, but it makes it super fast...jut do a yahoo search and you can find em...
you wont be able to cap L-dex, arimidex, or clen...but winny, nolva, clomid, var, d-bol, drol, DNP, even primo are all "capable"...here are the steps as easy as i can explain.
step 1- figure out what your gonna use for a filler...i like corn meal, and protein powder personally...but you can use things like corn starch, creatine, glutamine and stuff like that...
step 2- fill the bottom of a 0 or OO cap with filler and then dump it out on a scale to see how much each cap holds...ie. a 00 cap holds .39 grams of protein.
step 3- math...say your useing Mr. T's capper that holds 50 caps...multiply .39 times 50 and you get 19.5 grams.
step 4- say were making nolva @ 10mg caps...so 50 caps times 10mg = 500mg...or .5 grams.
step 5- subtract your powder weight (.5g's) out of your filler weight (19.5g's) and you get 19 grams of filler, and .5 grams of powder...that mix will make you 50 caps @ 10mg.
step 6- mixing...mix the powder and filler real good in a ziplock baggie for 5-10 minutes...then heres my personal trick...get a flour, or powdered sugar sifter at wally world and sift the powder into a dish of some sort...
step 7- fill your capper with the bottoms of the empty caps...then pour your powder over the top of them.
step 8- work the powder into the caps with the plastic "credit card thingy"...and tamper the caps full untill all of the pwder is inside the caps...
step 9- put the top half of the caps on, and BAM! you have 50 Nolva caps @10mg per cap.
This applies to all gear...say you want 50 winny caps @ 25mg pre cap...same thing- (.39 x's 50= 19.5) and thats your filler weight. (25 x's 50= 1250mg, or 1.25 grams) thats your powder weight. Subtract 1.25 from 19.5= 18.25...so you need 18.25 grams of protein powder and 1.25 grams fo winny powder...mix, cap and BAM!...50 winny caps @ 25mg each.
And there ya have it...once again a very easy way to make orals...have fun!

Pharmaceutical Versions by SV-1 and Anabolic Master:
I thought I'd add this bit to what is becoming the "official" capping thread. Every powder/filler you work with will have different characteristics, so this will help in figuring out how much you need for proper dosing. The pic at the bottom is an example and shows a difference in powder weights/volumes.
Capsule Filling – Powder Displacement:
A pharmacist receives a prescription for 15 mg piroxicam capsules, qty. 48.
A #1 capsule filled with piroxicam weighs 245 mg;
a capsule filled with lactose (filler) weighs 180 mg.
How much piroxicam and lactose are required for the prescription?
Prepare sufficient powder for 50 capsules (2 extra).
50 x 15 = 750 mg piroxicam.
15 = x
245 = 180
x = 11 mg
15 mg piroxicam occupies a similar volume as does 11 mg lactose.
180 mg - 11 mg = 169 mg lactose/capsule.
169 x 50 = 8.45 grams lactose required.
750mg piroxicam + 8.45 grams lactose = Total to make 50 caps @ 15mg piroxicam per cap.
----------------------------------------------------------------------
Here is the dumbed down version. What SV-1 posted is merely a guideline which can be used in other situations. That's the difficulty, deciphering the important concepts and adjusting them to your unique circumstance.
Here are the steps:
1) Fill a capsule with your filler, including tampering if you plan on doing so with your 'real' capsules.
2) Determine how much filler weight occupies this specific capsule. This will give you a weight/volume ratio and you can determine the relative density of the filler.
3) Fill a capsule with your active ingredient (Anadrol, DNP etc.), including tampering if you plan on doing so with your 'real' capsules.
4) Determine how much active ingredient weight occupies this specific capsule. This will give you a weight/volume ratio and you can determine the relative density of the active ingredient.
5) Now you have to do the 'more involved' math to determine the correct ratio of filler to active ingredient.
1) Determine the dosage of active ingredient you'd like per capsule.
2) Say for example you want 10mg Dianabol capsules. You've determined your filler density to be 500 mg per capsule and your active ingredient density to be 400 mg per capsule.
Now you have to set up the two equations and then cross multiply and solve for the unknown.
10 mg Dianabol = Unknown mg Filler
400 mg Dianabol = 500 mg Filler
10 mg Dianabol x 500 mg Filler = 400 mg Dianbol x Unknown mg Filler
(10 mg Dianabol x 500 mg Filler) / 400 mg Dianbol = Unknown mg Filler
Unknown mg Filler = 12.5 mg
NOW you take the total quantity of filler that will fit in one capsule and subtract the Unknown Filler amount we just calculated.
500 mg filler - 12.5 mg = 487.5 mg filler per capsule
Now you've got all the information you need to make 10 mg Dianabol capsules. For every capsule you make you need 10 mg of Dianabol and 487.5 mg of filler, so for 50 capsules just multiply these two numbers by a factor of 50.

Keep going like this until it's all mixed. Then, you can put it into caps.
Why go through this extra work? Well try it at home with some pepper and salt. Try directly combining a small amount of pepper with about 8-100 times as much salt. Now look at the pepper distribution in the salt. Does it ever look really even no matter how much you mix. Unless you're really lucky, probably not. So, try the geometric dilution method and see how much better that works and think about that in terms of your powders and see which method you should really prefer.
-----------------------------------------------------------------------
Accurately weighing powders by SV-1:
I had another thought about this thread, and that was about the accuracy (or inaccuracy) of the scales we use. The methods looked at so far work great if you work in a compounding pharmacy and have access to extremely accurate (and extremely expensive) scales. But the scales most of us use are only accurate to +/- 100mg (including mine).
In the above example a single capsule of piroxicam was weighed and it came out to 245mg. Well if you weigh that single dose on a +/-100mg scale the result could be between 195mg-295mg (.2-.3 grams), A HUGE DIFFERENCE!
So how do we compensate for this?
Instead of weighing a single dose we'll weigh a complete batch, for a Capping Machine that's 24.
Load 24 empty caps into the capping machine, then fill all 24 caps with your powder (for this example I'll stick with piroxicam). Then turn the capping machine over and tap all the powder out and weigh it. It should weigh 5880mg (24x245mg=5880mg).
Now the +/- 100mg isn't that big of a deal because the result will be between 5830-5930mg.
Take this weight (5830-5930mg) and divide by 24.
5830/24 = 243mg
5930/24 = 247mg
So either way it's going to be VERY close to the 245mg you'd have gotten if your scale was 100% accurate.

15 mg piroxicam occupies a similar volume as does 11 mg lactose.
180 mg - 11 mg = 169 mg lactose/capsule.
169 x 50 = 8.45 grams lactose required.
750mg piroxicam + 8.45 grams lactose = Total to make 50 caps @ 15mg piroxicam per cap.
----------------------------------------------------------------------

5) Now you have to do the 'more involved' math to determine the correct ratio of filler to active ingredient.
1) Determine the dosage of active ingredient you'd like per capsule.
2) Say for example you want 10mg Dianabol capsules. You've determined your filler density to be 500 mg per capsule and your active ingredient density to be 400 mg per capsule.
Now you have to set up the two equations and then cross multiply and solve for the unknown.
10 mg Dianabol = Unknown mg Filler
400 mg Dianabol = 500 mg Filler
10 mg Dianabol x 500 mg Filler = 400 mg Dianbol x Unknown mg Filler
(10 mg Dianabol x 500 mg Filler) / 400 mg Dianbol = Unknown mg Filler
Unknown mg Filler = 12.5 mg
NOW you take the total quantity of filler that will fit in one capsule and subtract the Unknown Filler amount we just calculated.
500 mg filler - 12.5 mg = 487.5 mg filler per capsule
Now you've got all the information you need to make 10 mg Dianabol capsules. For every capsule you make you need 10 mg of Dianabol and 487.5 mg of filler, so for 50 capsules just multiply these two numbers by a factor of 50.

Instead of weighing a single dose we'll weigh a complete batch, for a Capping Machine that's 24.
Load 24 empty caps into the capping machine, then fill all 24 caps with your powder (for this example I'll stick with piroxicam). Then turn the capping machine over and tap all the powder out and weigh it. It should weigh 5880mg (24x245mg=5880mg).
Now the +/- 100mg isn't that big of a deal because the result will be between 5830-5930mg.
Take this weight (5830-5930mg) and divide by 24.
5830/24 = 243mg
5930/24 = 247mg
So either way it's going to be VERY close to the 245mg you'd have gotten if your scale was 100% accurate.
If you don't mind the taste, it is sooooooo much easier to simply suspend the powder in everclear or 151 and then measure it out with an eyedropper.
Not only that, but it's more accurate imho. I've never been able to achieve anything near an equivalent distribution using caps.
