What is Clen used for?

Engineered to mimic Clenbuterol effects, Clen is an ephedrine free and incredibly powerful fat burning supplement.

How do we do this?
 
Magic! No, just kidding.
 
The nucleus of the Clenbuterol molecule is separated in order to remove the Clenbuterol hydrochloride ester. While this gives it a shorter half life, it still has extremely good thermogenic properties. Taurine powder is added to the Clen powder and then suspended in alcohol.
 
Obviously, it isn't as strong as real Clenbuterol but you won't have to worry about jittery hands, increased heart rates and restless nights that are long-term side effects of Clenbuterol HCL.
 
Clen is used by bodybuilders looking to get ripped for a competition or even models looking to get rid of that last bit of fat before a photo shoot. It is without a doubt the best fat burner on the market when it comes to producing a rapid decrease in body-fat.
 
While using Clen, one of the biggest fat loss recommendations we can give is to drink more water, eat better and sleep more. Buying Clen will not instantly drop the excess fat on your body. It will supercharge your weight loss efforts and after taking Clen, results will come much quicker. So before you buy Clen online, we would challenge you to check out our blog and make sure you get equipped with some information.
 
If you're curious about where to buy Clen online, we have had Clen online since 2003. Originally in tablet format, Clen was transitioned into a liquid format for a better delivery system. It has quite a strong reputation among athlete circles and competitive bodybuilders as an incredibly effective diet supplement.
 
Clen is not a steroid. Back in the day, ephedrine was all the craze but we all know that products with ephedrine made people feel "jittery".
 
There is absolutely no ephedrine in our Clen.
 
Here's how it works - Clen increases thermogenesis, which typically raises your blood pressure slightly resulting in an increase in your body temperature. If you already have high blood pressure, we recommend you not buy Clen and push your luck. Thermogenesis typically raises the rate of metabolism, which of course means more calories are getting burned. More calories burned means less adipose tissue (which is what makes people look blubbery).
 
It is important to note that when using liquid Clen, a product that increases protein synthesis is highly recommended because whenever fat is burning, protein will also get zapped from the muscle. Any of our mass gain supplements will do a good job of counteracting any potential muscle loss.
 
Clen is no longer offered in tablet/pill form. It is now in an oral liquid format.

  1. The best fat burner

    I do have to say that their liquid version of Clen is the best. I was extremely scared to used it because I had heard stories of people claiming their heart was being affected with strong heart palpitations or super high heart race.

    I have to say I never had any problems or any side effects , just to tell you I was doing hit cardio and training and never felt anything once! I was burning so much fat it was crazy ! I love this product is really strong I will used again!

    This product is a really good quality hands down! I can't wait to use their other products

  2. Great Feeling and Look

    5 / 5 stars
    Reviewed by on 28th Aug 2017

    I have tried SOO many diet things and it seems since the Ephedra withdrawal from the market, nothing has seen to work good.

    I like this stuff because as everyone else has stated, it warms up your body as a thermogenic should without giving you a jittery feeling.

    The other thing I have noticed is the steady energy I have throughout the day, not that it gives you energy but it feels like it helps normalize my metabolism.

  3. Very Good!

  7. BE HONEST WITH YOURSELF (includes in-depth instructions)

    5 / 5 stars
    Reviewed by on 4th Aug 2017

    This isn't a magic syrup. Well, not quite. I've been taking this product for one cycle now and I can tell you without a doubt that it only helps. But it helps A LOT. Here's my experience.

    I'm a stocky guy. I'm 5'6, Asian, with 7.5" wrist, 44.5" chest, 43" hips, short legs and currently 30% body fat, with a 405 lbs powerlifting squat. I've always been a heavy set guy. Never seen six packs on my body, and never seen veins on my biceps.

    From the other reviews you see it makes you feel like you can eat whatever you want but still lose fat. But that's NOT true. I thought so at first so I ate whatever I wanted, eating around 3500 and even sometimes 4000 Calories a day of just unhealthy foods and barely working out. BUT, even with increased calories and decreased nutritional foods, I went from 29.8% body fat to ONLY 30.4% body fat. So, not much change. Barely anything really. But it really shows that when taking this product you can use it to keep you at maintenance. I'm excited to see what progress I can make WITH good diet and exercise, and if I could edit this review later on I will to let you guys know how I'm doing.

    HERE'S MY INSTRUCTIONS ON HOW TO TAKE THIS PRODUCT.
    I suggest that you start out by drinking 2 cups of refrigerated cold water. This will help numb your taste buds so it's not so bad. It tastes like cheap vodka and cyanide. Also a study says that you can increase your metabolism for the day by drinking 2 cups of water first thing in the morning. Look it up.
    Put the recommended amount under your tongue. The dropper they give you have a hard time getting the full 1 ml amount so I suggest you do two 0.5ml amounts.
    Hold it in your month for 15 minutes. This isn't included in the instructions, but I've taken drop medications before and the doctor said to hold it, so it'll better be absorbed into the bloodstream. During the wait you can either read a novel, do paperwork, drive to work, or even read your Bible like your mom always wanted you to.
    Drink another cup of water to wash it down. Look at that. You already drank 3 cups for the day. By now I've made my green tea and enjoy it.

    As someone who began figure competition diets back in 2004, I've tried many fat burners. This one is far and away the best. Within two weeks of beginning Clen, I started dropping body fat like crazy. I changed nothing else, just added the Clen. In fact, I'm competing in 7 weeks and had to add calories and cut the Clen dose by 25% so I wouldn't peak too early. This product is the real deal. Make sure you follow the directions and drink tons of water though. This isn't a product to be messed with.

    Did I say LOTS of water? You'll be whizzing, but it works and if you do any traveling, really pay attention to how your body handles the flood of H2O as you could need an emergency roadside :-)
