Pair two longevity compounds that work on completely separate biological layers — GHK-Cu remodeling skin/tissue collagen, NAD+ refueling mitochondrial energy and DNA-repair enzymes — so a single protocol addresses both skin/hair/wound quality and energy/cognition at once.
Why it matters
These two are said to hit different systems: GHK-Cu, a copper-carrying peptide, is reported to rebuild skin and tissue collagen, while NAD+ is described as refueling the cell's energy and DNA-repair machinery.
The published per-compound doses, timing, cycle length, the mechanism sources give for why it's combined, and the harm-reduction notes — the parts that took the most research to get right — are part of membership.
