Sermorelin- Summary
- Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
- Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.
