first timer

I've been a long time lurker on this sub. i'm very interested in mescaline and the experience that it may entail. ive tried shrooms, acid, dmt, and a many more different psychoactive substances. I have some mescaline HCI powder i was wondering what you guys would suggest as a good dose for myself and my girlfriend to try on our camping trip this weekend. Also what would you reccomend as the best ROA. ive done research myself, im just looking for peoples personal opinions and experiences and any advice if you have it to offer.
