help me should I buy, page-3

Its pretty simple. You are betting 30c to win $1.40. That's about 7:2 on an old fashioned bookies board. So if based on your research of the trial you think the prospects of success are better than 3:1, say 50:50 (even money) then you are getting way over the odds by buying now at around 60c. So that's a great bet.

If you think the odds of a successful trial are worse than 3:1 based on analysis of the average success rate of all P111 trials world wide then its a poor bet.

If you don't do any research at all then its just a bet,
