Cereus repandus syn. Cereus peruvianus

Help me identify this plant. Anyone know what kind of cactus this is? It gets big white and yellow flowers on it sometimes.

@columbiariver looks like my peruvian apple cactus 90% sure it's that or 10% maybe a San pedro cactus

Thanks @honestgreensco and @columbiariver. I think you're right @honestgreensco, I think it is a Peruvian apple cactus. Thanks again.😊

So I went online to look at pictures of the two possibilities you suggested @honestgreensco , and now I'm totally confused because they all look the same to me. (at least they do in pictures anyway) I was wondering if you had any suggestions as to how to tell the difference?

@Athrall the most accurate way will be to see its fruit. San pedro and peruvian apple cacti have the same genus which is trichocereus..san pedro is pachonoi and peruvian is peruvianus..both flowers are white and bloom at night..both fruits are red but the inside is different colored snd texture..the two plants are more alike then different...the different will be in the color as san pedro is dark green while peruvian apple cactus has a blue tint and in shade can be blue. Also san pedro spines

@Athrall are not spiky, more stubs. While peruvian cactus spines can be a inch long. Also san pedro ribs arent canyons but rather are barely indents, and peruvian cacti has deep ribs you can fit a hand in
