Well success is subjective, but I did learn to grow mushrooms and have taken them many times during the past 8 years. I have recently been successful at a mescaline extraction, though only a low dose(150mg mesc hcl) bioassay has been done as yet. My girlfriend and I have a secluded mountain cabin rented next month where the dose will be significantly higher than threshold. I have not tried DMT, but have been intrigued by it...
