sounds like many options.
the lsd is way better than all the others in my opinion,
you may like to mix the dmt once you are at or past peak of the acid,
all the rest is confusing to mix, and possibly not good for your longevity.
using lsd moderately you could have another 90 years of enjoyable experiences,
several of the others present challenges to health, do research on this, you have a whole week, you could learn a lot if you use google.
learn what ld50 means, and check the ld50 for all the drugs
read some reports
also be aware that some powdered drugs are safe in a few micrograms, but not in a few milligrams, or safe in milligrams but not safe in grams (most powders are deadly in gram plus dosages).
assess some addiction issues especially as relates to "pills" and "opiates".
many of them are not more fun than weed but less good for you.
then decide for yourself how you want to play and how much of your life you dare lay on the line for a few hours of maybe "fun", hey and, also watch over your buddies too.
