What Are Peptides?

Peptides are made up of amino acids, typically comprising between 2 and 50 amino acids. ­­Amino acids exist naturally in all living organisms and are also the building blocks of proteins. However, proteins have more amino acids in their chain than peptides.

Peptides can either be produced naturally by the body or synthesized in the lab. Research peptides are currently used in various fields, such as drug discovery and development, cosmetic and personal care, and agriculture. They are not intended for human consumption.

How do Peptides Work?

Different peptides work differently depending on their formulation.

Some may increase sexual desire by activating specific receptors in the central nervous system. Others penetrate the skin to moisturize it and increase collagen production. Still other amino acid derivatives may stimulate muscle growth by inciting the release of growth hormone (GH).

This research peptide holds immense promise as a potential treatment for sexual dysfunction. In multiple clinical trials, its administration produced an increase in penile activity in men with erectile dysfunction. [R]


This peptide has been proven to stimulate the release of growth hormone (GH) in different body cells. Heightened GH levels are essential to better quality sleep, enhanced stamina, and improved sex drive. [R]


Another growth hormone secretagogue (GHS), Tesamorelin has undergone multiple clinical studies. It has demonstrated the ability to improve cognitive function and protein synthesis in adults. [R][R]


Sermorelin is one of the few peptides that has exhibited the ability to increase lean body mass and height. Trials have further shown that Sermorelin may increase sexual drive and muscle endurance. [R][R]

TB 500:

TB-500 is a synthetic replica of Thymosin Beta-4, a small peptide found in the human body. In the only clinical study, it prevented scar tissue formation in patients who had suffered a heart attack.


Semax is a neuropeptide approved in Russia for the treatment of stroke, optic nerve disease, and cognitive disorders. Clinical trials in the country have linked its use to improved memory and attention spans. [R]
