Biotest, Pinnacle and Cytodyne (original makers of Xenadrine) actually teamed up to try to sell this to the bodybuilding consumers back in early 2000. Each had various stories as to how Myostatin inhibitors worked and how you have to have them etc. The active ingredient was "Cyctoseira Canariensis" which is a sea algae. The three companies actually grouped all of their products into massive 8-page ads and put this into most of the major bodybuilding magazines. Unfortunately, no human studies have ever showed that this algae blocked Myostatin genes in living humans. In the supplement industry it's always buyer beware!
