Please recheck the mg on the bottles because if it is .02 grams that's only just over 2gs a bottle. If you meant .2g a pill, then that would be 2g = 10 pills. The powder is way better for your money, but the reason it is so cheap is because it's fucking disgusting (also it's faster to distribute and easier to package than pills). You'd need to parachute it or mix it with orange juice which still tastes pretty bad. A user here mixes it with teas or something and filters it but anyway,
As for your question, if you are using to substitute for a strong sedative try 2 or 3gs first. If that isn't enough, add 2 or 3gs on top of that. And finally if that doesn't work for the oxycodone withdraw, do it once more. Getting off oxycodone vs a large kratom dose, very worth it IMO. So in total I wouldn't exceed like 8, 9, 10ish.
Id only ever gone to 7 I think, so I don't exactly know what happens too far beyond that. I guess if that isn't enough then come back and someone more knowledgeable can help.
