I was just wondering about people heres views on this. A company called celldyne pharma is selling a product called Folstaxan which supposedly has follistatin as the active ingridient.
In their testing with just one person (yeah I know!), follistatin was found in the blood after consuming their product and the persons myostatin levels fell around 37%. Not very scientific but there does appear to be other good science that supports the idea that follistatin is very effective in mice but I think most of this was done using genes. It does at least appear to be absorbed and have an effect on myostatin levels.
For those that are not familiar with myostatin, it appears to be a regulator of muscle mass, in simple terms, more Myostatin means less muscle and vice versa. Follistatin appears to play a part in reducing levels of Myostatin and so seems to increase the amount of muscle tissue. I think follistatin is found in minute quantities in nature particuarly in embryos and gonads - probably used to get the initial muscle mass in newborns. Folstaxan is derived from fertilised chicken eggs I would guess because of the relatively high concentration of follistatin.
Follistatin appears to have minimal side effects, may cause skeletal muscle growth of up to 400% (based on the gene knockout experiments) and acts fast. It sounds too much like a wonder drug but if it turns out to be for real, the implications are huge; muscle wasting diseases treated, super sized and extra lean cattle and other livestock, muscle regrowth for the elderly and of course making bodybuilding much safer (and probably assessible to everyone without steroids, GH or IGF1 or for that matter exercise). There is also something similar that is for bone strengthening which would be good for the elderly.
It is still very early stages but the potential for something like this is amazing. imagine if we could get 4 times as much prime beef off our cattle. imagine if the elderly had strong muscle and strong bones. Imagine people with muscle wasting diseases being able to lead active lives. Imagine the average weakling (or geek) now able to stand up for themself. I really hope that this is at least half as good as early indicators.
I would really appreciate the views of others on this board and any other research others have come across.
Take a look at these amazing pics of muscle improvement (That second mouse really does look like a mouse equivalent of a bodybuilder):
