What are Peptides?

April 5th, 2013

It has been in the news a lot about some Australian athletes using Peptides to boost performance. Being someone who loves sport and being fit I decided to have a look and see what they are talking about.

Here is a brief snippet from the ABC News website for those who might be interested like me…

Growth hormone releasing peptides

Peptides are short chains of amino acids and are the building blocks for protein.They occur naturally in the body but can also be taken in supplement form.

Some peptide supplements are legal, and work similarly to protein supplements to help the body recover from strenuous activity. However, there are also a variety of peptides that encourage the body to release growth hormones.

These type of peptides stimulate muscular growth with fewer side effects than anabolic steroids. They are sold either as a cream or in a solution for injection.

The ACC report notes that various types of growth hormone releasing peptides, including hexapeptides like GHRP-2 and GHRP-6, are being used. The report notes that these type of peptides are also used in combination with anabolic steroids to maintain muscle gains.

From an anti-doping perspective, the ability to detect the use of growth hormone releasing peptides is complex, as the substances are rapidly metabolised.

Growth hormone releasing peptides are prohibited by the World Anti-Doping Agency (WADA).
