What does the research say about Fortagen?
Whey protein, which is quite popular in the athletic industry, and is relatively well regarded, was shown to achieve just 18% anabolic usage in human subjects, with vegetable protein sources being under 10%. Protein from meat fared slightly better, but even so, less than 40% of ingested protein was used anabolically.
This means that for an athlete trying to supply the body with protein for the purposes of lean tissue growth, more than 8 out of every 10 grams of whey protein they consume may not be used for its intended purpose.
