GHK-Cu / TB-500 / Epitalon / BPC-157 / KPV / Biotin
This protocol brings together six compounds selected for their complementary roles in supporting cellular regeneration, tissue repair, healthy aging, inflammation control, and structural vitality. Rejuvia is designed for individuals looking to support their body’s natural ability to renew, restore, and age with resilience from the inside out.
GHK-Cu (Copper Peptide) - Skin Renewal & Structural Regeneration
GHK-Cu is a naturally occurring copper peptide that is abundant in the body during youth but declines significantly with age. It is one of the most well-researched peptides in the context of skin health and cellular regeneration. GHK-Cu stimulates the production of collagen and elastin, the two structural proteins responsible for skin firmness, elasticity, and wound repair. It also promotes the remodeling of damaged connective tissue and supports the growth of new blood vessels, contributing to a more youthful and resilient tissue architecture throughout the body.
TB-500 (Thymosin Beta-4) - Systemic Repair & Flexibility
TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring protein found in nearly every cell of the human body. It supports healing and regeneration on a broad, systemic level by promoting cellular migration to sites of damage, reducing inflammation, and encouraging the repair of muscle, connective tissue, and blood vessels. TB-500 is also associated with improved flexibility and range of motion making it particularly relevant for individuals looking to maintain physical mobility and tissue integrity as they age.
Epitalon Cellular Longevity & Anti-Aging
Epitalon is a synthetic tetrapeptide modeled after a substance naturally produced by the pineal gland. It is best known for its ability to activate telomerase, the enzyme responsible for maintaining telomere length. Telomeres are the protective caps on our chromosomes that naturally shorten with each cell division and with age, and their decline is closely associated with the aging process at the cellular level. By supporting telomere health, Epitalon is associated with promoting cellular longevity, enhancing the body’s regenerative capacity, and supporting healthy tissue renewal making it a cornerstone of any protocol focused on graceful, healthy aging.
BPC-157 - Deep Tissue Repair & Gut Health
BPC-157 (Body Protection Compound 157) is a peptide derived from a protein naturally found in gastric juice. It has been extensively studied for its ability to accelerate the repair of soft tissue including muscles, tendons, ligaments, and the gut lining. In the context of healthy aging, BPC-157 contributes to maintaining the structural integrity of the body’s connective tissues and supports the gastrointestinal health that is foundational to nutrient absorption, immune function, and overall vitality.
KPV - Inflammation Control & Immune Balance
KPV is a naturally occurring tripeptide derived from the hormone alpha-MSH. Chronic, low-grade inflammation is one of the hallmark drivers of accelerated aging, a process sometimes referred to as “inflammaging.” KPV helps to modulate the body’s inflammatory response at the cellular level, supporting a healthier immune balance and reducing the cumulative tissue damage associated with prolonged inflammation. Its gut-protective properties also contribute to the broader restorative aims of this protocol.
Biotin - Hair, Skin & Nail Vitality
Biotin is a water-soluble B vitamin (Vitamin B7) that plays an essential role in the health of hair, skin, and nails, three of the most visible markers of youthful vitality. It supports keratin production, the structural protein that forms the foundation of these tissues, and is associated with reducing hair thinning, improving nail strength, and supporting a healthy skin barrier. As a well-established and widely studied nutrient, Biotin provides an accessible, evidence-supported foundation to the regenerative aims of this protocol.
