The use of Clenbuterol results in down regulation of beta receptors, and therefore, it is should be used for only short periods of time. A clen cycle generally lasts 2 to 3 weeks with a break in between cycles lasting equal to or longer than the cycle itself. The cycle should start gradually, slowly increasing the Clenbuterol dosage and then tapering off gradually. The average dose of clenbuterol is 60 to 120 mcg/day. Your best course of action is to start slow with a low dose, gauge the effects it has on your body, see how well your body handles it, and then slowly increase the dosage accordingly.
Whey protein is one of two types of proteins derived from cows' milk, with the other being casein. It is absorbed faster than other forms of protein making it an excellent choice pre and post-workout and after fasted periods (the first meal of the day). Whey protein has the highest biological value (BV) of any dietary protein and appears to have a synergistic effect with high GI carbohydrates, such as maltodextrin or dextrose. This is particularly recommended post-workout to increase nutrient delivery and glycogen replenishment. Studies have also shown whey protein to have benefits for weight loss through satiety (feeling full after a meal).
