QUESTION: Microdots

Just got offered a microdot by someone, and i was kinda curious if anyone on here in sydney has tried them lately, and if so, were they any good?

I had a little look at other posts on microdots and there seems to be also a variation in which format they come in, some say a little pill, others say a seed like looking thing. Any information would be appreciated.
Thanks

the only microdot i've seen was a small red ball about the size of a match head. they were similiar in appearance to 'hundreds and thousands'

they were pretty intense....

??

how long ago was this though? ive heard heaps of stories of microdots from ages ago, but nothing recently..
