Try again with purified harmalas & more DMT per gram of herb.
I know that for me 10x caapi leaf did not really do anything. It ends up producing what is essentially enhanced leaf. However, when doing a full acid base extraction on a good batch of caapi vine or rue seeds, i get full potentiation of small dosages of DMT, change in charecter, & a longer effect.
What i reccommend is that you start by getting some rue seeds & learning to extract from those. It is not hard but it is time consuming. Once you have a gram or two of freebase rue extract, infuse 250-300mg of that & 1g of DMT onto 1g mullein. Start with a 50mg dose from a bong.
