You are right on BIOHF. However, there are 2 other drug companies with not as good daibetes drugs but more money and marketing power.
If you want a very low priced stock with great potential in treating cancer but with a big legal battle, try HTTD. Hard to Treat Diseases apparently has a treatment that holds off terminal cancer (stage 3 and 4)in patients for up to 15 years. It supresses cancer similiar to drugs that contain the bad effects of hypertension, i.e., the person is able to live with the disease.
I have learned the hard way that whenever there is the potential for something great, there are big lawsuits. Greed is the big factor.
