Clenbuterol increases lean muscle mass but not endurance

Clenbuterol increases lean muscle mass but not endurance

Abstract

Clenbuterol, a beta(2)-agonist with potent anabolic properties, has been shown to improve skeletal muscle function in healthy subjects, and in high doses, promotes cardiac recovery. In a small, randomized controlled study, we investigated the effect of clenbuterol on skeletal muscle function, cardiac function, and exercise capacity in patients with chronic heart failure. Clenbuterol was well tolerated and led to a significant increase in both lean mass and the lean/fat ratio. Maximal strength increased significantly with both clenbuterol (27%) and placebo (14%); however, endurance and exercise duration decreased after clenbuterol. Prior data support combining exercise training with clenbuterol to maximize performance, and on-going studies will evaluate this approach.

Bodybuilding Peptides: How they work and why would an athlete use them

Bodybuilding Peptides: How they work and why would an athlete use them

 

So what are bodybuilding peptides?

Bodybuilding Peptides are a small chain of amino acids that isn’t quite long enough to be considered a full protein (less than 50 units).

They are, in essence, the building blocks that create protein.

In a supplement form peptides come in different chemical compounds. A few of these used within the  sporting community are known as GHRP-2, GHRP-6 and CJC-1295.

IGF, MGF and SARMs are identified as commonly used peptides used in the bodybuilding community.

 

 Why do athletes consider using peptides?

Peptides are used for their anabolic effect on an athlete’s muscle mass. (GHRP means growth hormone releasing hexapeptide, a type of growth hormone releasing hormone).

 

Bodybuilding peptides can be useful in a couple of ways.

Obviously an athlete will need to heal quickly and be productive soon after an injury. Peptides will help the muscle or soft tissue in this rebuilding healing process.

Supplements that provide an anabolic effect could also be used during pre-season and other periods where building muscle mass is important.

Muscle mass can be built quickly because the athlete can make small tears in a muscle and have it heal on a rapid schedule to continuously repeat the process – the end effect being increased muscle mass and reduced body fat in a shorter timeframe.

The bodybuilding community use peptides that are most effective in this second way as newer peptides don’t come with the side-effects of anabolic steroids.

Some peptides can induce fat loss when used correctly. Weight loss, more importantly, body fat in another key reason for using peptides. Greater weight loss at a faster pace than normally would be seen by exercise alone has been shown by many studies.

It is the links to bodybuilding and gym communities that help pro-athletes find new substances such as peptides to improve performance.

For some time now, the bodybuilding community has been aware of these supplements and the inability for testing to detect them in most cases.

This is especially the case if urine testing is the main form of detection.

Many peptides aren’t yet cleared for human use.

In fact, quickly perusing the peptide Wikipedia page , reveals they are mostly discussed in a scientific manner, not with reference to sports.

However, peptides are readily available on the sporting supplement market and aren’t very expensive.
Now we know what peptides are and what they can be used for.
