Capping is simple. Find a quick cap. Then just get a cheap food processor. Blend raw with filler(dextrose,creatine,glutamine,anything you want). You measure per batch of 50 caps and total mg per cap x 50 for the total mg per batch. Figure out what your cap size holds, add remaining filler, blend and distribute.
For 50mg caps they may end up with one 48 and another 52mg but honestly it's close enough and thru the week you get the same total.
You want to be clean but think about the things you can eat or put in your mouth that don't make you sick. Injectable has to be much more sterile.
