I think Animal Test was a decent product at the time of it's introduction, but I don't think it's changed much since it's inception. If you are looking for something better, and depending upon your age and what you're looking for, I would highly recommend CEL M-Test as something to give a try. I myself love it. There are several logs where people have had outstanding results. Better sleep quality, better erections, more frequent erections, bigger loads, increased libido, the works. PM me if you have any questions.
AlphaMax XT is another product I have used and I was impressed with the results. K1ngs Blood is another product that looks super solid.
