I heard other trichocereus might have similar (or even greater) amount of mescaline
than torch and pedro, is that true?
Here's a (non-exhaustive) list of mescaline containg species of trichocereus
Anyway "What is the most potent Trichocereus?" will be a very hard question to answer as it seems that people from many countries of south america will call "san pedro
" many different species of active mescaline containing trichocereus (not only pachanoi) so when you buy from the internet there is still some risk that what you get is another active specie (bridgesii for instance) that was sold as "san pedro"...so to answer the question one would first need to be able to accurately identify the specie that was sold to him for sure.
Also, just a tip: rather than putting your all money in 100g of each cactus, it would be suitable to buy only 30-50g of each of those species and then compare the effects of each at a 30-50g dose level, always using the same dosage so you can compare the potency from one to another (this way one would quickly find out which ones are the most potent without spending to much money...and neurones as you won't be using strong doses).
