Also, I forget the amount, but I am sure more skilled players here can fill you in, but Taurine supp should be used with Clenbuterol
NM I found some info here for you!
Muscular cramping
Cramping whilst using Clenbuterol is a fairly common side effect. This is most probably due to depletion of the amino acid taurine in the liver together with deficits in the electrolytes sodium and potassium, as well as inadequate hydration. Taurine helps stabilize cell membranes and prevent nerves from becoming over-excited. Some studies show that giving taurine supplements relieves painful muscle cramps. Japanese researchers found that the longer rats exercised, the more taurine they lost from their muscles (Matsuzaki et al, 2002).
Symptoms of cramping may be alleviated by:
Eating fruit particularly bananas
Ensuring adequate hydration
Taurine supplementation - 3-5g daily
Potassium supplementation - 200-400mg daily taken before bed on an empty stomach
