Does Anabolic-Matrix make you gain weight or retain water. This might be a stupid question but I have gained 4 pounds since I have been on it. I eat about 2600 cals a day. I do the 40/40/20 macros. Not changed anything since I started taking it. I started it 4 days ago and weighed 203 now I weigh 207. I am just trying to understand where the extra weight is coming from in just four days. I do not think I would of put four pounds of muscle on. If I have I do not notice it.
