Peptide therapy involves the use of specific peptide compounds to help regulate and optimize various physiological processes and systems in the body. Peptides are short chains of amino acids that act as signaling molecules in the body. There are many different peptides that have been identified and synthesized for therapeutic use. Some of the most common peptide treatments aim to increase growth hormone production, help with weight loss, build muscle, and improve cognitive function. Peptides work by binding to specific receptors on the surface of cells. This binding interaction triggers intracellular signaling cascades that induce targeted effects in the body. For example, growth hormone releasing peptides (GHRPs) bind to ghrelin receptors in the brain. This stimulates the release of growth hormones from the pituitary gland. Increased growth hormone levels help promote fat burning, muscle growth, healing, and cellular regeneration. Other peptides like melanocyte-stimulating hormone (MSH) promotes weight loss by decreasing appetite and increasing metabolism. Thymosin beta-4 is a peptide that accelerates wound healing and tissue repair. Cerebrolysin is a brain peptide that can improve memory and cognitive decline in dementia. There are even peptides being studied for their anti-aging and longevity effects. The key advantage of peptide therapy is the ability to target specific physiological systems with precision. Because peptides act directly on cell receptors, lower doses can be used compared to other drugs or hormones. This helps reduce unwanted side effects. Peptides are also well-tolerated with few reactions. Peptide therapy is administered through subcutaneous injections, topical creams, or intranasal sprays. The peptides can come in lyophilized powder form and need to be reconstituted with bacteriostatic water before injection. The frequency of dosing depends on the condition, peptide type, and individual response. Often a loading phase is used to rapidly elevate peptide levels before moving to a maintenance phase. Some of the most common uses of peptide therapy include:
