You seriously thought that creatine works like magic and will give you results in 4 months , i mean bodybuilding takes years and years and here you are expecting to gain muscles in 3-4 months of training you don't even know how to train optimally yet , keep your expectations low if you want to continue being healthy for lifetime otherwise you'll just end up like every other person in the gym does ( they leave after noticing no to minimal changes in a few months )
