The Youth Stack is BRAVO1's longevity-focused dual-peptide protocol, combining GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) and Epitalon. Each peptide targets a different but complementary dimension of biological aging — GHK-Cu works at the extracellular matrix level, driving collagen synthesis, wound healing, and skin regeneration, while Epitalon targets the cellular nucleus, with research suggesting it activates telomerase and supports telomere maintenance.
Together, they address aging from two angles: the structural decay visible at the skin and tissue level, and the deeper cellular aging reflected in telomere shortening and declining pineal function. The result is a stack designed not just for how you look, but for how your cells age.
The name reflects the protocol's intent — not to reverse age, but to support the biological mechanisms that govern how we age, giving the body the peptide tools associated with cellular youth and renewal.

GHK-CuGlycyl-L-Histidyl-L-Lysine Copper
GHK-Cu is a naturally occurring copper peptide that stimulates collagen and elastin synthesis, promotes wound healing, activates antioxidant enzyme systems, and has been extensively studied for skin regeneration and anti-aging effects. Research has shown GHK-Cu can upregulate over 4,000 genes — many involved in tissue repair, anti-inflammatory pathways, and cellular longevity. In the Youth Stack, GHK-Cu drives the structural and aesthetic dimension of the protocol: rebuilding the extracellular matrix, restoring skin quality, and activating antioxidant defenses.
EpitalonEpithalamin Tetrapeptide (Ala-Glu-Asp-Gly)
Epitalon is a synthetic tetrapeptide derived from Epithalamin — a naturally occurring polypeptide from the pineal gland, developed by Professor Vladimir Khavinson. Among the most remarkable research findings is its apparent ability to activate telomerase, the enzyme that maintains telomere length — one of the key biomarkers of cellular aging. Epitalon also regulates the hypothalamus-pituitary axis, increases pineal melatonin secretion, and has shown antioxidant and immune-modulating effects in aging research. In the Youth Stack, Epitalon targets the cellular and systemic dimension of aging that GHK-Cu does not directly address.
