Hey motor,
Sorry to say that I think it's definitely the PC clone. I have one in my house. Real pachanoi tends to have these little creases coming out of the areoles, kind of looks like how you draw single-line seagulls on paper...? Yours looks exactly like mine. When I juiced it, (skinned, chopped, blended, boiled(pressure cooked), squeezed/strained, repeated 2 more times and then drank the tea...my wife and I had a great mellow lucid experience... Mostly because of all the other alkaloids present in the cactus, but when I tried a mescaline extraction, it yielded very very little.
If you're looking for a very mellow experience, with mild visual distortion and an overall enjoyable time, juicing it like I said above works great.
Good luck bud!!!
