Good to know that your diet was changed. It didn't sound like in from the original post.
You can stick with those products forever basically. They all serve a scientifically backed purpose and are relatively inexpensive.
One thing that I forgot to mention that people typically use on cutting is an EC or ECA stack. Ephedrine, caffeine, aspirin. Most typically ditch the aspirin and just stick with the EC portions. Basically, you start popping 200mg caffeine (you can find it in walmart or wherever for cheap --ask where they have something like NoDoz, and buy the generic brand) and about 25mg of Ephedrine HCl or Ephedrine Sulfate. You can find the sulfate version over the counter in the form of Bronkaid or for the HCl version there is Primatene, but it only comes in 12.5mg of ephedrine hcl per pill. Either way, I havent found a difference, pick one, take one 200mg caffeine and one 25mg serving of ephedrine sulfate/hcl and see how you feel. If you can handle that, take two. If that's fine after a few days, you can up it to three doses of EC. That can help you with cutting. I know Charles Poliquin jumps up and down about how it raises cortisol but I can't find that anywhere else.
In terms of other stuff. There is a whole lot of stuff out there. Some stuff works and some doesn't necessarily do what they claim. That said, what additional kicks are you looking for? What do you think you need to perform better?
Stuff like NO-Xplode or whatever is popular for energy boosts. Its basically a bunch of stimulants with some nitric oxide to relax your smooth muscle and allow more blood to rush giving you a bigger 'pump'. Yea it may feel nice, but it wont do anythin performance-wise and its like 60 bucks a container. Theres a bunch of garbage like that....none of it is really worth it.
In a few years if you've hit you've put on a lot of muscle, have your diet fully under control and can reach low body fat levels...and you have reached your genetic limit...and you are willing to handle the physiological, social and legal risks... check out the Anabolic Zone section for a legitimate boost.
...and don't forget your multivitamin.
