Yes. There are actually capsules available on amazon. To my knowledge, two 500 mg capsules, twice a day (2g daily) is sufficient in providing anti-cancer benefits while being completely non-toxic.
The cyanide myth is blown entirely out of proportion. Yes, poisoning is possible. But it takes a much larger amount than in a capsule or from eating apricot/apple seeds. Chemotherapy is monumentally more poisonous to the body than b-17. It is much more likely to be deficient in b-17 than to have too much of it. There are dozens of testimonials online (and YouTube videos) of people claiming they cured their cancer with this. It can even be use as a means do preventing cancer at the proper dose. Of course, you should do your own research and come to your own conclusions on what is safe or not.
