Maths to ~1:500 to 1:1000 but ingredients are fine... One thing to keep in mind, a lot of regulated markets have odd definitions of stuff the end result is folks doing products like these to skirt regulation. The downfall is you often don't get a good analysis on the products, because of their formulation, because of their labelling, and because of how they are skirting regulation.... a lot of the signalling molecules in these types of brews have critical levels transition to detrimental levels very quickly (like a doubling of PPM in a single hormone). Long story short, I'd lean to the 1:1000
