Doubt it. Even if they do it is for a very short period. Very transient and not long enough to lead to anything. That is why I said not in any meaningful way. But we may not be talking about the same things.
Most hgh releasors or "secretogogues" are scams. Even the ones that have stuff that may increase hgh release won't promote sustained hgh release. And others are complete snake oil altogether.
And it seems to me, although this is just speculation, that is would be just the opposite with "releasers". If your body is not good at relaeasing it's own hgh then a releaser would not help much. Whereas it would do more for a younger person who is alread good at releasing it...that is if it worked in any significant way which it almost definitely doesn't.
And you also need to be careful of some of the ingredients used in some of these things. Do you really want ground up cow brains? Hell look at some of the fancy proteins for sale. People will put any crazy thing in a sup. Look at ergopharm's protein. Bovine plasma....the liquid portion of cow blood. YEAH! Give me some cow plasma.
