I have taken this stuff in the past and noticed it helps to suppress my appetite and gives me a bit of a jolt that coffee or Redbull gives some people. I found it on Suppz.com and decided to take it again. I just started so I haven't lost any weight yet, but I feel that it helps and it's not expensive.
I've taken caffeine-based stimulants for years but Yohimbine had a totally different effect on my body. It felt like the first time I took caffeine. Every muscle in my body felt buzzed and I was ready to tackle any machine at the gym within about 15 to 20 minutes of my dose. I'm not going back to caffeine any time soon.
