I just took the average dose that the dealer was selling, I live in a rural area, so my most prices are inflated, especially with rare items (I swear to God, DMT prices over here are obscene). I naturally assumed that it would be the optimal dose. I just got off the phone with him, and he said that it was about 15mg. I doubt I'll give it another go however, due to the exorbitant pricing. Sorry about the misinformation, I thought that my experience was the norm.
