Yann with Ayahuasca

I’ve been doing crossfit for about 5 months now and i’ve lost a LOT of fat, put on some muscle, and lost a small amount of weight. I did that without using any pre-workout products. When i started to need more exercise a couple of weeks ago, i looked for things to give me that extra boost and up my performance a bit.
I asked around, and i tested these two products. They are the same in just about every way.
Do they work?
Are they healthy?
What results can you expect? Are there better alternatives? I give a good free tip that absolutely works for me, here in the video. And guess what, it’s free and non-toxic.
