i used hydroxycut hardcore before and it did nothing for me....but it must work for some people.
I found this stuff called Stimulant X that i ((love)) and plan on using again after I'm through with Phen...it works really well! plus you can get a free sample pack from the website to try it out for yourself...and if the price isn't right you can get it a lot cheaper on the supplement warehouse website for about half the price (if you can find it cheaper they will match the lower price as well)
this is the only otc pill I have ever used that has worked after the banning of ephedra..it's really great.
i hope it's ok that i posted links
