So I think I'm going to make my first changa and from what I've read a lot of people are in love with the blend Electric Sheep. Can anyone tell me the exact ingredients and how much a g of spice. Thanks! Also I'm open for any suggestions for any blend for a first time changa user.

50:50 calea and blue lotus, 1:1 dmt to herb ratio
but thats enhanced leaf not changa, you want caapi leaf or some MAOI in there for changa.

is the calea or blue lotus an extract or as is? Also I have some harmine HCL that I'd like to throw in there but I don't know if HCL can be smoked. I also have some access to some 20x caapi leaf and if I wanted to make a changa with the Electric Sheep what would be the ratios you think?

Only freebase harmalas can be smoked, the salts are for eating.

If by "access" you mean you will buy so pre-made 20X caapi leaf, don't do it! Make your own for a fraction of the price. get an ounce or so of plain caapi leaves and go with your preferred method of doing that. The information on how to do that is all over the place on the Nexus.
