the easiest way i have done it, for example i used anadrol at 50mg/cap
it would be nearly impossible to make capsules with only 50mgs of just anadrol in them......at least with the homebrew instruments you have
1 gram of anadrol is equal to 20, 50mg anadrol tablets........so in order to do it right you would need to add a filler. I used some powerade mix, because it looked pink and helped to remind me that it was anadrol
now take whatever your filler is....in my case powerade drink mix
fill one capsule up.....tightly pack it in......using the capping machine "damper" or whatever you can find to pack the powder in there. Cap it..then put it on the digital scale.....
now say the cap weighs about .5g. In order to make 20 capsules you will need 10 grams of powder to fill those 20 caps. Measure out 9grams of filler (powerade) and then your 1 gram of anadrol added to it will make 10grams total.
I suggest making a larger amount for say 100-200 caps. It makes your dosage more reliable.
After measuring out your filler and anadrol amounts, place them in a container that you can shake the hell out of. I shook mine for nearly a half hour to make sure it was mixed as accurate as it could be.
I prepared enough for 100 capsules at 50mg/cap and i needed 50g of filler (powerade) to fill my caps. I subtracted the 5 grams of anadrol i needed from that 50g of filler, resulting in a mixture of 45 grams filler and 5 grams of anadrol to equal 50g total.
Make sure that you shake this well. I had them tested and i ended up with 10 capsules ranging from 44mg/cap to 53mg/cap
This is the easiest way i know of.
