RE: ADVANT LABS
Rebirth should really only be used by those who are typically 18%+ and rarely get and maintain below that level of bf.
Myself, i sit happy around the 12-14% cause i drink beer and eat sweets if i'm not dieting. Otherwise i can probably sit quite happy in the 10-12%, but unfortunately i have stubborn fat around my chest and lower abs that make this level of bodyfat not look as impressive as you'd expect. For me, LeptiGen Basic is the ideal choice for mimicking leptin and help blunting hunger as i diet.
