Everything I've read from them indicates it's the same chemical, but in a specific formulation. It's described in detail in the patent (one of them: https://patents.google.com/patent/US20200199161A1/en)

From what I can tell from searching for "Comp360", it is simply synthetic psilocybin. See https://pmc.ncbi.nlm.nih.gov/articles/PMC10595939/
