By far the first thing I have to mention are some forum rules under the, "attitudes" section at the top of the page, which are absolutely clear in stating:

Now, do not take this as in insult. I'm very happy that you believe how well psychedelics can benefit mankind.

To start helping the community all you need is a positive attitude, and an open mind to the infinite impossibilities that most of us encounter day by day, and subsequently everyones highly unique interpretations of every experience. In short, never take a single person for granted because their experiences may seem more insane than others. Always keep in mind why each of us is on this forum, and how, "crazy" what we do really is. And I do realize that because you are here in the first place, you've already taken this step

There is an endless amount of valuable information that you can learn before you take your first journey into the world of hyperspace, but know one thing, no one is ever ready for their first breakthrough experience. It truly is unimaginable.

Only?! It only takes 30-40mg for most people to get a full breakthrough experience, but there have been reports on breakthroughs involving much less amounts. Dose really does not matter, although there exists such a thing as too much (75mg+, and that's still a lot!), and micro dosing.

Enter your journeys with a clear mind, and don't go trying to decipher each experience too quickly, or over analyze. It will hurt your head. It's been many months since my last breakthrough, and I still think about it every day.

Welcome to Nexus, my friend. Enjoy life!
