I am a first time user of this product and let me start by saying it is phenomenal. I paid just about 48 bucks at gnc the first week of the month, cheapest way to get it. I have gained 6 pounds in exactly two weeks and i didn't even follow the directions. The bottle instructs that you take three in the morning and three before bed. I have been taking it just before bed, I also combinated it with a protein shake. My bench press has also increased 40 pounds, f.y.i you will get freakish looks at the gym. Imagine this, i weigh 185lbs but now bench 265lbs in sets of 8. I feel like an animal and I am damn proud of it. I won't even get into the sexual side effects of this products. It will take me at least 2 paragraphs to list the positive effects. The only side effect i have is confidence. Its worth the money.
