Hmm, while only having tried liberty caps once, that dose of 1.5g was maybe like 3g of cubensis.

My first mushroom trip was maybe 1.5 g cubensis and it was quite immersive. The way I see it, those shrooms do what they want anyway, and you never know how strong a dose will feel.

In my humble opinion I would say 1g of liberty caps should be enough for a first timer.

Otherwise good luck with your thing, psychedelics can be great for bonding
