Don't purchase bleaching gel products blindly. They are not all identical. As an example, the recommended treatment times associated with seemingly similar hydrogen peroxide and carbamide peroxide whiteners will probably not be the same. In the majority of cases the bleaching agent your dentist originally dispensed to you will have been a carbamide peroxide whitener (the historical 'standard' for tray whitening technique). Of course, with any product you purchase you need to adhere to the recommendations stated in its instructions.
In regards to concentration, if the whitener you originally used produced pleasing results without creating a problem with side effects, why not duplicate your previous experiences by purchasing a bleaching gel with the same composition and concentration? Whatever choice you make, use your past bleaching experiences as a reference point when selecting a concentration. If you experienced no side effects with your past treatments, yet the bleaching results were less than you expected or took an excessive amount of time to achieve, you might consider a whitener with a slightly higher concentration.
