When I see something rated the "highest" or "#1" or whatever, with no details about who rated it, why, on what criteria, how many rated it, etc., I get a little suspicious about marketing tactics.
GENF20 looks OK, but a lot of the testimonials are based on sex drive. That really makes it suspect, to me. It is claimed that growth hormone increases sex drive. But increasing testosterone definitely increases sex drive. When I see a growth hormone product where sex drive is mentioned and things like tribulus testris or wild oats are in the ingredients, which raise testosterone and/or free testosterone but not growth hormone, I get suspicious.
How about GABA? 50mg is insignificant for raising growth hormone in my opinion. The study that I read said that they used 5 grams (5000mg) to get the rise in growth hormone. Does that mean it has to be 5 grams? No. Surf used 1500mg and she grew well. Beth used IGF-1 losenges. They are all good, but the real growth hormone can only be obtained through a prescription at thousands of dollars per dosage. I think that taking amino acids, the dosages should be at least 1500 to 2000mg per day, sometimes for each dosage depending on what it is and why to take it.
The best thing to do is to take significant amounts of these amino acids (like at least 2000mg per dosage) and look at the supplements that contain "anterior pituitary" and possibly "deer antler velvet." The amino acids are good but for those in the > 55 range, the anterior pituitary and deer antler velvet are going to be the best ingredients in my opinion. The purpose of anterior pituitary is to try and get the brain to trigger production on its own. Deer antler velvet is supposed to contain HGH. I have no idea if it is significant, but I would suspect that it is only in very small trace amounts.
I am not currently taking a growth hormone supplement but if I were it would either be this one:

GENF20 looks OK too, I wouldn't rule it out. But the other two would be higher on my list to try first.
Growth hormone is produced during the first 90 minutes of sleep. Insulin inhibits growth hormone production, so avoid anything that will give an insulin response for three hours before bedtime. Get plenty of good sleep - like earlier in the evening. Night owls are going to have a harder time. If you can get some time working out with weights - weight training will also make the body produce growth hormone. Anything that you can do to increase circulation is also good. Many of the amino acids also do this. The best ones are omega-3 fatty acids (flaxseed oil in the case for NBE), Gingko Biloba, and anything that raises Nitric Oxide such as L-Glutamine and L-Argninine.
Go to the links above and read about the ingredients. Become experts on what the ingredients are and you will know what each of them do. Here is the one for GENF20:

I thought I read up there somewhere that there was an interest in the HGH supplement that Chiyomilk used:

I have no idea how one would purchase this outside of Japan.
