hello everyone - hope you are well

i recently bought about 80g of peganum harmala, and i wanted to make my freebase dmt last longer by using these seeds. but i am not quite sure of the process how to do it. i think i should do a extraction of the peganum harmala.. like this one and then get this extract, mix so much of it with dmt. i would have no idea how much to use thou. any help would be great.

take care
