Secretagogues promote hormone secretion. So it's probably something that stimulates the pituitary gland into releasing more GH. No idea if it works, how effective it is or what the side effects could be.
The second looks like some kind of pro-hormone. Even if I knew how it worked, I'm not sure you could guarantee it won't turn into estrogen without taking aromatose inhibitors.
Anogenin doesn't appear to be hormonal. Apparently it aids in protein synthesis. Might get converted to a pro-hormonal molecule in your liver, who knows. In theory it means your body will synthesize more protein, rather than breaking it down for calories. You can achieve a similar effect by spreading out your protein intake over the day, without the potential for side effects.
Dust looks to be a mix of caffeine, amino acids and electrolytes. Probably healthier than slamming a couple of Monster's and a Gatorade.
Going off Aus prices, that would be around $300 a month. Steroids would probably be a lot more cost effective. The pro-hormones look to be banned here, though that doesn't mean they're effective. If it was my friend, I'd advise him to eat a lot of cruciferous vegetables and probably dump some cash on a synthetic aromatose inhibitor as well. Do a liver detox after a 'course' as well, because the pro-hormones get converted in the liver, so it will be working overtime. Not to the extent of real steroids, probably, but who knows?
I'd be interested to see how well all of this works. Post results if you see them. I'd be happy with anecdotes, but timestamped pics would be better.
