Par deux,
I appreciate your taking the time to point out the problems with my logic. You are correct about drugs and herbals, but as I understand, most Ripped Fuel does not even contain ephedra, and the Ripped Fuel that does contain ephedra contains 111mg of ephedra standardized to 6%.
Cards110's question is subjective. By "better" he could be questioning which supplement promotes fat loss and is less stimulating, more thermogenic, or the better appetite suppressant. I am not sure what he would mean as better, but I am certain that pill for pill, the drugs in Phenyltropic PPA are a more potent combo than the herbals in Ripped Fuel.
Additionally, there are quite a few studies that indicate that in animals, PPA has a definite thermogenic effect -- specifically on brown adipose tissue. Take a look on Medline.
I am impressed with your knowledge and would appreciate your help with a new herbal diet formula I am working on. I would appreciate your comments on the following:
Caffeine 200 mg
Yohimbine HCL 3mg
Ephedrine Alkaloids 25mg
N-ACETYL L-TYROSINE 500-1000mg
