You need to read the label, most fat burners just have caffeine and green tea extract as active ingredients, both of which raise metabolism, or stop metabolism slowing as part of a calorie restricted diet.
No Doze is just expensive caffeine and fairly low dosage really, not sure why anyone would buy it. Here is 360 tablets with 200mg caffeine (double the dosage of no doze) for $30 delivered.
Caffeine Tablets 200MGS PRE Work OUT Intesifier 120 Tablets 3 Packets 360 Tabs | eBay
Just buy caffeine tablets on ebay way cheaper option will do the same thing as Hydroxycut. If you want add either Green tea Capsules or Green Coffee capsules.
Bulk Nutrients sell a fat burner combination as well as Green Tea capsules, both will help. None of these are magic ingredients though you need to have diet and exercise in check for them to assist in any way though, diet 75% exercise 20%, supplements 5%, now ask yourself if the $$ are worth the 5%.
Here is three month supply for $53:
3 X Pure Green Coffee Bean Extract MAX Strength 800mg Chlorogenic Acid 60 Caps | eBay
I would stay away from Hydroxycut and the like once you have run out and just make your own plan up using the above if you still want to supplement.
