If no one responds or nobody here has tried calea, erowid.org has people who write experiences on their experience w/ a good amount of drugs... i find it easy to just type in google what your looking for along w/ "erowid experiences"... so just go to google and be like "calea erowid experience" and check it out.
Many times people give body weight and their dosage and its easy to find out what dosage you want accordingly(read the experience see if thats what you wanna do).
