Clenbuterol

Quick info about Clenbuterol

Clenbuterol (Clen) is a selective beta-2 agonist/antagonist and a bronchodilator. What this means, is that it stimulates your beta-2 receptors. So what exactly dose a stimulant like Clen (or Ephedrine) do when it stimulates those Beta Receptors? It serves to increase your body temperature a bit by increasing heat production in the mitochondria, increase your basal metabolic rate, and decrease your appetite.

You'll need to take 20mcgs upon rising, and then repeat that same dose again later in the day, and then once again in that day (if you find you can tolerate the effects). So you'll start with 20mcgs, and then repeat that dose 2 more times that same day if you can tolerate it (classic stimulant side effects will determine this: hand shaking, sweating, etc.). You can then start increasing the dose gradually. It is not advisable to work your way up to more than 200mcg/day. 60-120mcg/day is an average dose, but keep your blood pressure at (or under) 140/90, while on Clen, just to be safe. If you go over that, lower the dose. You can take some ketotifen every 3rd or 4th week that you remain on Clen. It's a prescription anti-histimine, so it'll make you drowsy (take before bedtime). Basically, the way this works is to reduce beta-2 receptor activity, and restore receptor function.

Let's examine ephedrine for a second. Remember when I said that using clenbuterol to stimulate the beta-2 receptors is like hitting a tack with a hammer? Well, ephedrine is like a sledge-hammer; it hits the beta-2's and everything around them. Ephedrine reduces Beta-2 receptor levels to 32% of control after 24 hours.

Performance issues with Clen also vary. Some studies show reduced exercise (cardiovascular) performance, while some show that Clen can alleviate exercise induced asthma! Finally, this brings us to the issue of cramps while on Clen. Most of us are athletes who use Clen during the season as well as the off season claim that it gives him more "wind" (cardiovascular stamina). Take on enough water every day and you should be fine. If you're really concerned, you can take some extra minerals and taurine, since Clen depletes taurine (11) as do most if not all beta-agonists. I don't take anything more than my usual vitamins and minerals.
