This product does work but like all products... You gotta work for what you want. If you sit there like some ppl i know, youre gonna get minimal results with some lean muscle gain. Dont expect a magic drug that makes you massive by itself! All those ads are garbage! Now if you stick to a routine and work for your goal, This product does improve muscle gain and strength! I gained 10 pounds of lean muscle 3 weeks into the cycle before i got injured. This was a shipping problem but the package was dmged and one of the bottles werent sealed.
