Tell or Say please, peroxide of Hydrogenium, that that is on sale in a drugstore, - what % of the maintenance or contents (on a label it is not underlined)? Simply I need 6 %.

Hello! In drugstores 3 % a solution of peroxide of Hydrogenium are on sale. 6 % prepare for a solution of peroxide in retsepturno-industrial (these departments are not in all drugstores) departments under the prescription of the doctor.
