Iam making research on nmda antagonist (PCP, mxe family) on their nootropic effects, good or bad but i was interesting myself in the way steroids work, however I don't expect much than an hour relaxing with documentary media, but it as well fascinating for me even if I feel like steroids are mostly used for Mass and body looking which mean cannot expect any healthy improving, which I will say the same on psychede that way, however the receptor playing a role there are much more role precise than the one for psychedelic i think, someone correct me on this if needed,but I suspect that nmda antagonist can be in some way some brain steroids, which all the risk it have offcourse, most of the interesting stuff I found are on ncbi but there not much research anymore or not as I expect compare to the potential of them as well as steroids where the effect is really "visible"
