so you know the so first of all I should tell you that Merck company from Germany is giving us the placebo admit forming right a drug is free so when when you say nobody's interested it's true it's generic but actually Merck has the worldwide license for MIT forming and they're actually giving supply to lots of studies because they kind of realize that this is good do you think there's a difference between generic metformin and branded in terms of efficacy is there any reason No so there really this is kind of uh this isn't necessarily a creative to them because one can buy metformin generically anywhere they're not going to make more money from giving us this will you know I should say even now a lot of them it forming suppliers have higher sales and a lot of them are non diabetic yeah so this thing which is which is bad for me because I don't want too many people to know that right I want to do this study I don't want and I don't I want what you'll have you know I don't think hopefully I won't impair your recruiting
