This is a generous sample sized jar.  It is my 3rd little jar of this size.  I find they last about 2 weeks each with 1x nightly use, or a bit less if used more often, because a little of this goes a long way for me. I think this small jar is overall a good value, and certainly, big enough to really have a chance to work, if it is going to, for any given individual.  If you like it, then you can buy the larger sized jars.
