Your daily supplements will usually depend on your goals.
But for most people, the most used supplements are a whey protein and a multi-vitamin.
If a person is taking certain AAS, they might take a liver protector. If they are taking Clen, they might be taking Taurine and potassium.
If they are cutting, they may take a fat-burner or appetite suppressant. They might also take Glucorell-R.
For bulking and/or cutting, a person might take Glutamine too. Preferably the peptides.
Other people might take Ginger Root to help digestion of protein.
It all depends on what you want to accomplish.
