One of the more interesting links regarding anti-aging science:

Be sure and click on links at the bottom of the page as they are all also very interesting.
Oh, in regards to muscimol, it is a GABA A selective receptor agonist:
http://en.wikipedia.org/wiki/Muscimol
It has been shown to increase LH however, to my knowledge, it is not available to the consumer but only to science for testing. Many think that GHB although mostly utilizing GABA B receptors also acted as a GABA A receptor agonist similar to that of muscimol which is maybe why GHB was addictive as muscimol also induces euphoria.
I'm sure many of you remember mushroom tea when you were young

Muscimol is produced naturally in certain mushrooms.
It is interesting to note how there is a fine line between what makes you feel good and is bad for you, and what makes you feel good and is good for you. The latter of the two is what anti-aging medicine hopes to accomplish someday. The authors on the study of the aging primates clearly indicate that muscimol may have healing properties yet, because it can provide that dream state you may never get to take advantage as with GHB, L-dopa. etc., etc.
