i was thinking of using green teapills and caff 400-600mg and aspirn, but how do i dose the aspin

I would just take one asprin. It is hard on your liver so you don't want to be taking a ton on a daily basis, just stick to one pill to go with your tea.
Also, Basic Cuts is a cheap fatburner from Designer Supplements, goes for $14.99 @ Nutraplanet, in case you were looking for stuff to stack.
Sounds like the ECA stack http://www.kevsworld.cc/eca.html
500 mg Green Tea, 200-400 mg caffeine, Cardio...
M.Ed. Ex Phys
i dose it about 30 min before cardio, or ur WO
As far as cheap product I think Venom Hyperdrive 3.0 is a pretty cheap / long lasting product.
E/C/A, E/C/Y, Clenbuterol, Albuterol. Those are all decently cheap.
I don't know how low your BF is, but if it is already decently low, using a moderate dose of Napalm just before your cardio is good. You can make a bottle last pretty long if you use it right.
