 So from my experience, did it build muscle? Was it very, very effective? Yes, very, very noticeable. I would notice it almost felt like it worked for like a half the day or most of one day. Again, this is one scoop and this is a very small scoop. I'm like 220 pounds. So maybe I needed a little bit more or maybe this has a short half life and you need to take it once in the morning, once in the end, I don't know. Every time I took this, I had extra strength. My visually, just my muscles looked better, more bigger and more stronger. The more that I would consistently take it, the more that I could see it. I would get in the gym and I would constantly be surprised. I would go put my normal weight on and then I would feel like, ah, I kind of want to go a little heavier, kind of want to go a little heavier, kind of getting surprised about my strength increases. Now, it's not something like insane, but I mean, really it was about 20 or 30% as far as strength gains, as far as everything in the gym. I was just really, really impressed by it.
