The reason that clenbuterol can only be used for 3 weeks in a row is because of the downgrading of the beta 2 receptors.

There is a way around this of course, which will allow you to get more of the effects of clenbuterol while taking it less and in some cases even extending your cycle to 8 weeks.

The most simple and the cheapest way to increase the effectiveness of clenbuterol is to take a course of Benadryl, which can easily be purchased over the counter. This will decrease the downgrading of your receptors, allowing you to achieve greater results while on your 3 week cycle. It is not however available in dosages strong enough to increase your cycle length.

The other way to increase the effectiveness of clenbuterol and allowing you to increase the cycle to up to 8 weeks is Ketotifen. Ketotifen is a very strong anti-histamine that blocks the receptors from being downgraded completely. Technically you could continue to taking clenbuterol for an undefined time without ill effect, this is not recommended.

Want to give your clenbuterol a cheap boost? Try adding a bit of Taurine to your diet, in other words, by a can of Red Bull to slightly boost the effect of clenbuterol.
