I used a two week cycle of Mag-10 and i put on some good weight with little orno rise in body fat (its hard for me to get fat for some reason). Anyways, my strenght was up too which was great.
However, i did experience some sides such as increased acne. Actually, there was only one side which was increased acne. I got it on my shoulders, chest, face and a slight increase on my back. They were not huge zits, just like little small ones underneath the skin. I think the advantages outweighed the sides.
Also, i took my Mag-10 on an empty stomach and 30 minutes afetr i ate breakfast. I didnt get any stomach irritations at all. But everyone is different.
