MX335 is MX135, except that it smells like grapefruit instead of chocolatini.
I did try it by itself (as MX135), at first with not much success. I did finally have a time when I had some minimal effects and self effects, posted in this report - MX135. I ran out of my To-Go of it, then ordered the MX335 because I really like the grapefruit scent also..
I feel as though I had better results when I mixed them for some reason
Now my MX335 To-Go is getting low 
I would love to try it solo some more though, I think perhaps my environment might not have been the best for that particular MX.
I really like both scents though, I would love to have a big bottle of both MX135 and MX335 (different scents for different times 
)
My birthday is coming up next week (hint hint 
)
Has anyone else had better results with mixing these, than from using them solo??
