There are finally enough hours in the day to embark on the journey with Aya, however, I'm reticent to begin. I'm a gym rat, and take several supplements such as fish oil, a multi-vitamin, protein, etc. My main concern however, is pre-workout supplements. They contain relatively high amounts of caffeine, synephrine, yohimbe extracts, etc.

My question is this: How long should I abstain from these substances before embarking?

I use preworkout supplements as well and never have any problem, I usually abstain from them at least one day before. I think the goal of these ayahuasca diets is more about cultivating long term awareness of health in relation to diet. Ime the longer you prepare for the session with diet and meditation etc. the more you are setting yourself up for possibility of deeply healing experience. That being said I have drank aya with little prep and still had amazing experiences.

But to answer your question more directly I think your ok just to not take it the same day as your planned session and you should be ok, this has been my experience anyways.

Which preworkout are you taking?

I can only say, that i once had a protein drink in the morning and did do pharmahuasca in the evening. I had a bit stomach unpleaseantness, but i´m pretty sure that was because of a high harmine dose (i took 200 mg which seems to be high for me).

I've been taking C4, but recently switched to a GNC line product after a friend recommended it. Too much caffeine for my taste. I really enjoyed iForce's Conquer. I just don't want to have too much stim in me and take an maoi and blow a gasket.

Before embarking on any kind of entheogenic journey, I always give myself 24 hours to prepare (no supplements, pills, or junk food), and then 16 hours of solid fasting before I ingest.

I find it beneficial, although I would be the first to acknowledge that the ritual might just be 'priming' my brain, making into a kind of placebo effect, but it works for me.

I have used C4 and before and gave it 36 hours abstinence and used aya with no side effects I was aware of. Idk about the one your on now but just give it some time off and you should be ok. I think you would be fine as long as you don't dose the preworkout prior to your session.

To be safe though you should go through the ingredients and check their interactions with maoi's.
