Understanding the science behind our products. Learn what peptides are, how they work, and how to handle them properly.
Peptides are short chains of amino acids -- typically between 2 and 50 -- linked by peptide bonds. They are smaller than proteins but share the same fundamental building blocks. In the body, peptides act as signaling molecules that communicate with cells to trigger specific biological responses.
Unlike traditional pharmaceuticals that often have broad systemic effects, peptides are highly selective. They bind to specific receptors on cell surfaces, making them powerful tools for targeted biological modulation. This selectivity is what makes peptide therapy a growing area of biomedical research.
The human body naturally produces thousands of peptides that regulate processes ranging from immune response and metabolism to tissue repair and hormone secretion. Supplemental peptides are designed to mimic or enhance these natural signaling pathways.
Subcutaneous injection delivers the peptide directly into the bloodstream, bypassing the digestive system for maximum bioavailability and rapid onset of action.
Once in circulation, peptides bind to specific cell surface receptors with high selectivity. This lock-and-key mechanism ensures targeted action without widespread systemic effects.
Receptor activation triggers targeted biological processes within the cell -- from tissue repair and growth hormone release to metabolic regulation and DNA repair.
Our product line spans four core categories, each targeting different aspects of health and performance.
BPC-157, TB-500
CJC-1295, Ipamorelin
Growth hormone optimization peptides that stimulate natural GH production. Used in research on body composition, recovery, bone density, and sleep quality improvement.
Semaglutide
Weight management and metabolism peptides that regulate appetite, improve insulin sensitivity, and support cardiovascular health through GLP-1 receptor agonism.
Proper storage ensures peptide stability and efficacy. Follow these guidelines to maintain product integrity.
Store unreconstituted peptides at 2-8 degrees C (36-46 degrees F). Avoid freezing unless specified. Keep away from direct light.
Use bacteriostatic water (BAC water) for reconstitution. Inject water slowly along the vial wall to preserve peptide integrity. Do not shake.
Unreconstituted peptides remain stable for 24-36 months when properly stored. Once reconstituted, use within 28-30 days and keep refrigerated.
