If I recall correctly, you can get yohimbine powder for less than $8 for 3 grams. I put it into a medicine bottle with distilled water. $8 for better results seems worth it to me, but to each his own. But I like yohimbine since it allows for a constant supply of fat to be available for metabolism, making it less likely for the body to resort to muscle catabolism. I have no proof for that, but I believe to be true. What you believe affects the body way more than it should.
I do not know what's best. I would go by how I felt, since most anything you take will only have marginal effects compared to your diet and training. A slightly higher metabolism is nice, but feeling better during a cut will go a lot further in helping you achieve your leanness goals.
