Clenbuterol was formulated by pharmaceutical companies as a medication for people suffering with asthma, this product however has unique fat burning properties which has made it widely used in the bodybuilding community. Many people mistake clenbuterol for being a steroid, this is false, clenbuterol instead belongs to a class of drugs called sympathomimetics.

How to use Clenbuterol:

This drug is often taken alone or with steroids as part of a cutting cycle. Dosages vary between male and females and it is also recommended that doses are pyramided to lessen the side effects.  Typically males can tolerate a dosage of between 100 to 120 mcg a day and females up to 80 mcg a day. Clenbuterol causes Beta-2 receptor down regulation and thus it becomes ineffective after about 2 weeks of use, for this reason many people choose to cycle clenbuterol 2 weeks on 2 weeks off or 2 days on 2 days off. These are also drugs such as ketotifen which keep the receptors “clean”, taking ketoitifen with clenbuterol allows users to continuously use this fat burner for as long as 8 weeks without it becoming ineffective.

When using clenbuterol with steroids the popular choices are usually winstrol and testosterone propionate. The steroids help build lean muscle and maintain muscle mass while on a low calorie diet while the clenbuterol shreds off fat at an impressive rate.

A typical clenbuterol cycle for a male will look like this

Day 1 – 40mcg

Day 2 – 40mcg

Day 3 – 60mcg

Day 4 – 80 mcg

Day 5 – 80 mcg

Day 6 – 100mcg

Day 7 – 100mcg

Day 8 – 120mcg

Day 9 -120mg

Day 10 – 120mcg

Day 11 – 100mcg

Day 12 – 80 mcg

Day 13 – 60mcg

Day 14 – 40mcg

There are many different theories when it comes to cycling clenbuterol, many people believe you don’t need to pyramid down the dosage, the above example is just an opinion and is not the right or wrong way.

Clenbuterol side effects:

While side effects are usually dosage dependant many people initially see the following side effects when on this drug

  • Muscle cramps
  • Hypertension
  • Increased heart rate
  • Palpitations
  • Insomnia
  • Dry mouth
  • Vomiting
  • Tremors

Most side effects generally subside within a few days, side effects such as muscle cramps can be prevented by supplementing taurine. If after a few days you still getting side effects then lowering the dosage usually will fix this.

Buying Clenbuterol:

Clenbuterol is available in a number of different forms, namely, granules, liquid, tablets, capsules, cream and an injectable version.

Because the dosage of clenbuterol is so small it is recommended to only buy pharmaceutical brands so that you can be sure you are taking in the correct amount, many underground labs produce clenbuterol but because of the minute doses it is very easy to make mistakes. There are many websites where you can buy clenbuterol online, these websites often sell their own brands or pharmaceutical brands. Pharmaceutical clenbuterol is cheap and so there is really no reason to buy low quality underground brands. If you can only find underground brands then first do your research, make sure you find out what other people say about the brand and if they are happy with the results. There are a lot of research sites selling clenbuterol online at very cheap prices, this clenbuterol comes in liquid form and is often good quality as long as its from a reputable site.
