San Pedro Cactus Identification Help Please

[kwd]

Can anyone please help me identify whether or not his is a san pedro cactus? I can include more photos if needed.

It is approximately 20' tall - I have not seen open flowers yet...but included are pics of unopened flower buds currently growing.

Definatley not a Pedro, the ridges are too skinny. I had a friend just recently think he found the "Motherload". Turned out to just be Peruvian apple which is what that appears to be. Nice looking cactus though

I'm in a similar situation. This cactus has five ridges, and they are not as swollen as T. pachanoi seems to be; I didn't get to see it flower. Still, I'd like to know if it would be active. Can anyone identify? Any insight would be appreciated.
