The Ketotifen will keep your Beta 2 receptors in good shape,Its usually used while taking a clen and t3 cycle! Meaning you can use Clenbuterol for longer up to 6 weeks. Clenbuterol can not safely be used for longer than 3 weeks, without a 3 week break, unless you are using Ketotifen daily from the second week!

Ketotifen take 2 tablets a day everyday before bed from week 2-6.
The thing to remember about Ketotifen is that is makes you drowsy and you should not take it in the morning or before driving your car always before bedtime

Ketotifen fumurate is sold under the brand name Zaditor. It is also available from many underground labs, typically for use with clenbuterol or sometimes mixed with it.

Action

Ketotifen is an antihistimine that inhibits down regulation of beta receptors, which are often degraded by fat-burners such as Albuterol and Clenbuterol.

It can be used in combination with these other drugs in order to keep feeling their fat-burning effects for longer periods of time with out the need for periods of on and off cycling. Side effects can include drowsiness, irritability, nosebleeds and dry mouth. Ketoifen increases appetite; therefore another side effect is typically weight gain. Ketotifen also (potentially) improves insulin sensitivity within muscle tissue.

Technical Data

Because Ketotifen has the ability to stimulate the appetite, it has been studied for use with wasting conditions. In the most commonly referenced study examining this property, 22 AIDS patients who were administered Ketotifen and Oxymetholone, 18 gained an average of 11.4 pounds after just under 4 weeks (1). Further research proved Ketotifen to be a TNF-alpha blocker. TNF-alpha lowers testosterone and IGF-1 levels immensely (2,3) while strenuous exercise raises TNF-alpha levels (4). TNF-alpha has also been found to inhibit the muscle's ability to uptake glucose, (which is known as insulin resistance). It has recently been discovered that hypogonadism and low testosterone are also associated with elevated TNF-alpha (5).

This would seem to indicate a potential use for Ketotifen in Post-Cycle Therapy.

User Notes

Ketotifen was first introduced to the bodybuilding world by Dan Duchaine, who proposed its use for upregulation of Beta – Receptors. Several years after his passing I figured out that Benadryl would work for the same purpose, and Ketotifen was largely abandoned for the more commonly available Benadryl.

It is, however, due to the late Karl Hoffman that we owe the use of Ketotifen for reducing TNF-a and for possible use in PCT. He pioneered this idea (though it didn’t really catch on, per se), and it would seem to be very beneficial as an anti-catabolic, though it’s cost would make it prohibitive for use in up-regulating Beta-Receptors.
