I suggest that before you take drugs that you know little to nothing about, it's a good idea to google them, go on Wikipedia, and read the FULL ARTICLE (I know it's SOOO hard, but education will keep you from ODing or worse).
After you have edumacated yuseff on the drugs that your planning to take, make an edumacated descision weather ur naught u wannar taker ur drugs ya dig? Decide a dose (start with the reccomeded therapeutic dose) and stay outta trouble!
