I know someone who has is a PhD Pharmacologists. For years I tried to get him to take A*****ose. After he was finally diagnosed with terminal lung cancer he was interested in glyconutrients. Of course always the sceptic he did his own research (FYI he also had a company that he formultaed a nutritional product for). After doing his own research he decided he would order the raw ingredients and make his own. Didn't work and he finally switched to Ambbrotose and is getting excellent results.
You can play around with it if you want. But if you have a potentially teminal situation it might be a gamble.
