I’ve never used them, and have no feedback really, nor in some cases do I even know the ingredients, so I’m at a loss to respond. I mean, on some specific questions I have an opinion (which on the other might be refuted by some of their research) – for example that growth hormone releasers may produce a pulse of GH release that shows a higher value at a specific time, but this does necessarily not mean more total GH over the course of the day, but just getting the same sooner, and no added anabolism – but again, I don’t have specific information on their products and so wouldn’t want to comment further on the products themselves really.
