Active: Ketotifen Fumarate
Ketotifen or Zatiden as it is also known is used in conjunction with Clenbuterol. This means during a clenbuterol cycle the receptor begin to break down losing their sensitivity. You need a higher Clenbuterol dose to get the same effect. As time goes on the body has less and less reaction to Clenbuterol. Because of this it was always good practice to use clenbuterol in a “two day on two day off” fashion. This gave the receptors a chance to clean out and become sensitive once again.
Ketotifen has the action of clearing the receptor sites almost immediately making them sensitive again. To achieve this, they use it at night. Dosage is one 2mg tab at night. It is best to take Ketotifen at night because it makes you drowsy. By using Zatiden you can use Clenbuterol virtually non-stop for days or weeks. It is however not advisable to use Clenbuterol over long periods of time. 4-6 week cycles are generally the norm. Because of the Zatiden, Clenbuterol is far more active over the same period of time as using it without Zatiden so shorter cycles should yield better result anyway.
