Clenbuterol

Is this good for fat loss?
If so how does it work?
Side effects?
Safe for female use?
Any Details?

It would be much easier to use the search function than to have to wait on answers.

use the search engine. if i remember correctly, P-22 laid out a clen protocol in one thread. and both he and a few other members (mikekatz i believe) have spoke on clens overrated fat burning properties.

I am not qualified to say whether it is effective or not, but I will say this.

I ran into a bro of mine at the gym the other day. The guys about 6’5 270 pounds and he has got muscle, but he had some chub on him as well.

Well it had been about two weeks since I had seen him and when I did there was a definite noticeable difference! His arms which were always muscular looked more defined, his face looked leaner, and his mid section looked smaller.

Like I said it was very noticeable and this was two weeks. I told him I noticed his leaness and he relayed to me that he had been on Clen for the past two weeks.

Now this guy has an injured foot and hadn’t been doing much if any cardio or leg work.

Again I don’t know of it’s effectivness or dangers, but the results on this guy were noticable.

I am the guy Elk spoke of. I had never used clen before but because I don’t like the shakes and all that, but I had a chance to get some, and it has worked very well for me. I am taking it along with T-3, and I have gone from 295 to 260 in about a month. I did lose about an inch off my arms (20 to 19), but everybody that sees me comments that I look bigger. And the best thing is, no shakes, no palpitations, but my body temp is up and I can feel it working. I did stop at two weeks and take benadryl to reset my receptors. I wish I took before pictures.

I’m in the market for clenbuterol, could you guys reccommend a good source? Or should I ask around in the gym?

if you are in a border town by mexico it is very easy to get just go to the pharmacy and ask for spiropent.

I tried it, it made me anxious, shaky and freaked me out a bit. I used it for a few weeks then tipped the rest of the container down the sink (I know, I could have sold it to one of my mates!)I prefer ephedrine. That’s a buzz I can deal with.

Just my personal experience.

Clenbuterol (often referred to simply as ?Clen?) is a Beta 2 Sympathomitetic and CNS stimulant. It is a specific agonist, stimulating the adrenergic beta 2 receptors. It is used in certain countries in a medical sense as a bronchodilator in the treatment of asthma, though not in the U.K/U.S. mainly due to it?s long half life.

However, athletes/bber?s utilise the drug due to its thermogenic and anti-catabolic effects. This is down to it?s ability to slightly increase the body?s core temperature, thereby raising calorific expenditure. It is thought that a 1?F increase yields around a 5% increase in maintenance calories burned. Studies on livestock suggest that clenbuterol has anabolic properties too. However, this is not the case in humans, thought to be due to the fact that humans lack the abundance of beta 3 receptors which increase insulin production and sensitivity.

What are the side effects?

Side effects are dose dependant, though most users will find that most tend to subside with persistent use. Caution is advised when employing the use of Clenbuterol in conjunction with other adrenoceptor agonists as side effects are likely to be cumulative. It is for this reason that it is generally not recommended to use ECA whilst administering Clen. Common sides would include:

Headaches

Muscular tremors (especially hand shakes)

Muscular cramps

Nervousness

Insomnia

Sweating

Increased appetite

Nausea

Palpitations

Hypertension (high blood pressure)

In view of the above side effects, it is obvious to assume that anyone with cardiac issues and/or hypertension should not use a stimulant such as Clenbuterol. In addition, caution must be observed by those already using similar compounds in the treatment of existing medical conditions.

Commonly employed dosing protocols

It is well known that Clenbuterol use results in rapid down-regulation of beta 2 receptors. This is due to the powerful stimulatory effect of the drug. It is therefore pointless to use Clen for long periods without a break. Some believe that a 2 day on, 2 day off dosing schedule will allow adequate potential for receptor up-regulation. However, I doubt this to be the case due to the relatively long half life of Clen, resulting in continued stimulation even throughout the ?off? days. A much better regime would be a 2 week on, 2 week off cycle.

A tapering up of dosages is recommended in an attempt to limit harsh side effects. Most commonly, a user will start by taking 1 20mcg tab on day 1, followed by an increase of 1 tab on subsequent days. Subject to personal tolerance levels, a dosage of 140mcg (7 tabs) will be used by day 7, and this level should be maintained for the entire second week. It would be fruitless to exceed 7 or 8 tabs daily due to receptor over-saturation. There is no requirement to taper down.

During the 2 ?off? weeks, an ECA stack can be used as required. ECA will not cause such a pronounced down regulation and desensitization of the receptors, certainly not to the extent of Clen. Ephedrine has a short half life in contrast to Clen which results in times throughout the day where the beta’s will partially recover from stimulation by adrenaline and nor-adrenaline. Potency is also much weaker that that of Clen, as it is not a specific agonist. Ephedrine is also thought to increase the conversion of endogenous/exogenous T4 to T3 through the activation of deiodinases responsible for this process. This is important as Clen is known to slow the rate of T4 to T3 conversion.

As a side note, some bber?s will use T3 concurrently with the Clenbuterol/ECA cutting cycle (together with certain anabolic/androgenic steroids no doubt!) in an attempt to at least maintain T3 levels.

Cycles of Clen/ECA are normally limited to 12 weeks in total, though are often shorter.

Female dosages tend to be slightly lower than those of male users, with an upper limit of 80-120mcg (4-6 tabs).

Aside from it?s fat burning properties, Clen is often used as an anti-catabolic to maintain muscular gains following a steroid cycle. A dosage of 40mcg daily would be suited to this situation.

Dosage Timing

There is no particular requirement to split the dosage throughout the day due to the long 36hr half life. Most will take the full daily dose in the morning, though some prefer to take their dose just before bed so the user avoids most of the side effects as they sleep.

Some user accounts suggest that splitting the dose may lessen side effects slightly. It is a trial and error process in essence, to ascertain which method suits you personally.

Muscular cramping

Cramping whilst using Clenbuterol is a fairly common side effect. This is most probably due to depletion of Taurine in the liver together with deficits in sodium and potassium, as well as inadequate hydration. Symptoms can be alleviated by:

Eating bananas

Ensuring adequate hydration

Taurine supplementation @ 3-5grams daily

Possibly supplementing with potassium

Ketotifen

Ketotifen is an anti-histamine used medically to treat bronchial asthma and allergies. It has a sedative and depressant effect on the brain. It acts by decreasing the release of histamine which is a chemical released when an allergic reaction occurs. Ketotifen blocks the action of histamine on special histamine receptors and reduces the nerve response when an allergic reaction occurs.

Histamine is the chemical in the body that causes the symptoms of an allergic reaction. These can include inflammation of the skin, airways or tissues, rashes, itching and of the skin, eyes or nose, nasal congestion and narrowing of the airways.

By blocking the actions of histamine, ketotifen may prevent and relieve the narrowing of the airways that occurs in asthma due to allergies.

However, bodybuilders are interested in the drug as it has been shown to inhibit the down regulation of the beta receptors, including the beta 2s that clen stimulates. As long as you are taking ketotifen, it will continue to clean these receptors, never allowing them to downregulate ? even while on a heavy clen cycle. That means you can continue to take clen indefinitely without having to cycle off to regenerate the receptors. 2-3mg ED can upregulate even severely shut down receptors within a week.

It also means that you don?t need as much clen to get the same benefits. It seems u can take about 30-40% less clen and it be equally effective.

No studies have been done to find the most effective dose though most users should find 3-4mg ed ideal, which can be split or taken in one sitting. Higher doses are likely to cause (sometimes severe) drowsiness and increase appetite.

I was going to write something myself but would not have managed to do anywhere near as good a job as this.

frogie2001, that was extremely informative thank you. It will help in my decision whether or not to use. You said some take it at bed time to avoid sides. It won’t keep you from going to sleep?

I wouldn’t take any before bed. i think that the side effects are no more than an effective thermo and so may keep some people awake. However normally by the time i hit the sack nothing can keep me awake.

How much T-3 do people use? There is a product Synthroid that has both t-3/?T-4…anyone know how much? Thanks.

Clen only works for about a week or two unless you stagger the dose like 2 days on one day off. Even then your body stops stops responding very quickly. With long term use there is severe rebound effect, which means you get fatter if you are “on” for long peroids.

I would look at the supps. on this site like HOT-ROX or Carbolin 19. You can stay “on” for 8 weeks or more with no rebound effects. Just tighten up your diet and increase your energy expenditure by adding sprints or better yet “the TABATA”.

I am running it with a very small cycle of deca 300, 300 mg per week just to spare some muscle. As I said, everyday people are asking me how I lost all the weight, if I’m getting ready for a show, things like that. It’s kinda wild. I am not, nor have ever been a bodybuilder, just a big guy. Different things affect different people different ways, and this has worked great for me.
Diet wise, I have maintained a high protein diet, and cut way back on the carbs. Yes it’s a dangerous drug, but I chose a long time ago to play this dangerous game. Drugs can be used, and abused. If you are smart, you should be fine. Just my .02
