It's really going to depend on exactly how much caapi you take, and how much mushrooms, how strong they are, etc. Liberty caps are weaker per gram than cubes, which are weaker than something like pan cyan, right? But with a good caapi dose I think you should expect it to at least double the power of the mushrooms, maybe a lot more. So if you take something like 5g of mushrooms, be prepared for that to be like taking at LEAST 10g. It might be smart to start with less than you'd usually take, see how it goes, and work your way up.
