There is a cheap supplement called GABA that some body builders take because they think it helps them sleep, and makes more growth hormone.
Well, supposedly it can't cross the blood brain barrior. Many sites sing its praises, but I finally found reports saying that the study in the 70's that claimed it increased HGH production 5x was never reproduced, even with many attempts. Another study found it increased levels when taken before exercise, but they had a small group and tested for HGH, not IGF1. HGH comes out randomly in big spikes, so the results could be by chance in the small group. As for sleep, people say it makes their face tingle and relaxes them to sleep. I took some, and it did make my face tingle, and did relax my muscles, but did not make me fall asleep. I guess it could help, but it is not guaranteed at all. After 10 minutes of tingling, the tingling went away and I was back to normal. I still say the best way to fall asleep fast is to masterbate.
