Increase in Aerobic Capacity: Clenbuterol
The drug Clenbuterol results in an increased aerobic capacity of the blood, which is the amount of oxygen carrying capacity of the same. The increased oxygen transportation in the blood is as a result of the property of being a thermogenic drug. Clenbuterol gives rise to a higher body temperature, as it affects the thermogenesis of the body, and increases the fat burning and breakdown of glycogen. These result in the greater availability of energy for the cells, in the form of glucose and ATP.
Such features of the drug are attractive to athletes who need a boost during endurance events; however, the use of Clenbuterol is restricted in certain countries. Clenbuterol is a beta 2 adrenergic agonist, which helps release fat cells from the adipose tissues and release energy from the same. The thermogenic drugs elevate the body temperature, which in turn facilitate the breakdown of fat easily. The effects of Clenbuterol are similar to ephedrine, but Clenbuterol is more lasting than ephedrine, as it stays in the system for more than 24 hours.
The fat burning effect of Clenbuterol makes it a popular choice among body builders who want to shed excess fat and increase lean muscle mass. The increase in the aerobic capacity of the blood is also a favorable feature, as it helps for increased endurance during the training sessions, and for athletes who take part in endurance sports.
Clenbuterol Hydrochloride or Clen as it is known for short, comes in tablets and liquid, though the liquid is meant for horses, and is very hard to dose correctly for humans. Tablets come in 20 or 40mcg doses, but as men take 80-160mcg a day in one dose, and women take 80-120mcg a day in one dose, why would anyone want the 20mcg tablets.
Clenbuterol can only safely be taken for three weeks, after that the beta 2 receptors become worn out and the Clenbuterol is doing nothing to help, after a three week cycle of Clenbuterol, one must stop for another three weeks to let the beta 2 receptors recover. If you want to take Clenbuterol for longer than three weeks, you must take ketotifen tablets, 2-3mg a day of Ketotifen, taken before bed (it makes you very drowsy), means you can use Clenbuterol for 6-8 weeks without a break.
People often stack (combine) Clenbuterol Hydrochloride tablets with T3 Cytomel, combined Clenbuterol and T3 Cytomel tablets at the same time for 3 weeks will burn an amazing amount of fat. The T3 Cytomel stimulates your thyroid, when your thyroid is stimulated your metabolism rises and you burn fat extremely quickly. T3 Cytomel is also only ever used for three weeks, and then stopped for three weeks, taking Ketotifen does not mean that you can take T3 Cytomel for longer than three weeks.
