Its also very important to understand how and why clen works on some and not on others..if your beta receptors are saturated from other potent termogenics ranging from ephedra down to caffeine, then clenbuterol obviously won't have a strong of an effect. Genetics plays a part only when your beta receptors are prone to down regulating (becoming more used to the medication) quicker than others, this could explain why at 80mcgs, your shaking like a leaf, and three days later, at 200mcgs, your not feeling a thing. I'm referring to your pet lab rat when i say "you."
