Pill info Request: light blue horseshoe (sydney)

Looked on pillreports, one in melbourne of similar description, that tested clear, and was said to be K.
these aquired in sydney are:
light blue
horseshoe logo
flat on both sides
beveled edge
no score
tested: clear
Have been consumed and contents are unknown by me. I did find them to be quite trippy however. Just requesting to see if anyone has any idea of there contents.

I've always assumed them to be a decent whack of K - along with blue seahorses from the same source
