Peptides are small chains of amino acids. Proteins typically contain hundreds or thousands of amino acids; peptides are much shorter, usually containing between 2 and 50 amino acids. 

Research peptides are compounds produced for laboratory experiments and clinical trials. They allow scientists to study the effects of peptides in living subjects. 

Research peptides are not approved for therapeutic use and are only meant for research purposes, an important distinction from approved peptide medications.

Some examples of popular research peptides include BPC-157, TB-500, Epithalon, Thymosin Beta-4, and Sermorelin.

Peptides work like tiny messengers in your body, carrying specific signals to your cells and tissues. 

Here’s a breakdown of their action:

1. Signaling: They bind to specific receptors on cell surfaces, much like a key fitting into a lock.
2. Activation: This binding triggers various cellular responses.
3. Response: Cells then change their behavior based on the signal received.

Different peptides have different roles. 

For example:

• Growth hormone peptides tell your body to build muscle and burn fat.
• Collagen peptides help maintain skin structure and joint health.
• Antimicrobial peptides help fight infections.
• Insulin (a natural peptide) helps control blood sugar levels.

Extensive research has highlighted peptides’ potential for combatting age-related decline across bodily systems and organs. 

Here are some of the most promising benefits:

• Skin Rejuvenation: Peptides like copper peptides and Epithalon improve skin elasticity, firmness, hydration, and collagen levels, reducing wrinkles and age spots.
• Bone & Joint Support: Collagen peptides may increase bone mineral density, improve joint health, and ease arthritis symptoms.
• Immunity Enhancement: Certain peptides exhibit antimicrobial effects and may strengthen the immune response against infections.
• Muscle Growth: Peptides such as IGF-1 LR3, Follistatin 344, and GHRP can increase muscle mass, strength, and physical performance.
• Cognition & Mood: Semax and Selank mimic regulatory peptides in the brain and may alleviate anxiety, depression, brain fog, and neurodegeneration.
• Cardiovascular Function: Animal studies link Epithalon administration with improved heart function parameters and vascular regeneration.
• Metabolic Improvement: Peptides that increase glucagon-like peptide-1 (GLP-1) levels, like Semaglutide, improve glycemic control and help with fat loss.
