Okay guys;
Here's what I'm doing. The beauty about this method is that it does not require a scale or any knowlegde of the density of the powders(fillers and var)
It is tedious however.
You'll need a bottle of taurine by Ultimate Nutrition. It's a 150g bottle with 150 caps of 1g of taurine in each capsule.
Take 100 caps. Empty every cap(that's gonna take forever but it's var baby

) dumping the powder in a metallic/glass container.
Only dump 99g(99 caps) of taurine in the container, Throw away the one gram of taurine.
So far you have 100 empty caps and 99g of taurine in your container. Add 1gram of anavar and mix for a good period of time, mix as much as you can.
Fill your empty capsules using the cap-m-quik device
The anavar is only 1 gram and it represents 1% of the mixture so you can bet that it's a homogeneous mixture
Each cap is 10mg.
To make 20mg caps, do the same but use only 98 grams of taurine and 2grams of anavar.
