Different Types of Ketamine?

I'm a little confused after doing some research. What are the different types of ketamine, (S) and (R) correct? I see the (+) and (-) thrown around a bit too, what's up with that? What about R/S ketamine, is that when you have both? Is R/S ketamine what's known as racemic ketamine?
 
I've gotten different vials that were medically sealed and I had no idea what kind it was really, just that it was some pure shit.

There are threads if you search in ADD about some of the finer differences between some different kinds of Ketamine, but I've honestly never felt any real difference. A hole is a hole.
 
R/S is called Racemic.

The R and S isomers refers to chiral centers of a molecule. Like it is a mirror image of one another, such as your right and left hand. They are similar but different, and extend on the same plain of one another, but there is much further discussion on stereochemistry in the ADD. Basically if you look at your hands, your fingers are like the positioning of elements on say a phenyl ring, all of the elements are the same on this ring except the positioning (1,2,3,4 etc) is different.

There are also Enantiomers (mirror images of a chiral molecule) that are similar to what I was just mentioning but the molecules don't "match up". Often with Enantiomers only one isomer has the most desirable effects, but with other substances one isomer is dangerous for the fetus where as another is perfectly safe.

As an aside, you will also note D/L vs. R/S as well.

(+) (-) relates to the plain of polarized light, clockwise(+) vs. counterclockwise (-)
 
each brand of ketamine (talking about legal vials here) contains a different mixture. most are racemic, but there are some that are S only. These are harder to find, at least IME.
 
there seems to be difference in effects from batch to batch as well. i used to be like Ketamin is ketamine is ketamine. but sealed redlabel is a lot diff than some crystal shards ie * preform, ketacholride, base K or whatever the current slang is now.
