I find Metaburn to work well in females, as they seem be more affected by non stims IMO. I have a client now on Metaburn, she loves it. It will work in males, but like anything, some people who are not sensitive to stimulants need STRONG STRONG stuff... If you are comparing it to say CRAZE or DNC stack..then of course it is not as strong. Metaburn is a very safe yet effective product.

What I can also say about Metaburn is that if you look at the ingredient list and then the price, it is very inexpensive for what it contains.

If Metaburn doesn't work for you personally..ECA is certainly something I always have stood by as an effective product.
