The science of growing older — without surrendering to it. This collection maps the evidence across copper peptides, hormonal transitions, mitochondrial health, and the food-as-medicine angle. Six deep dives, one curated place to start.
The anti-aging thesis
Aging is not a single event — it's a cascade. Telomere shortening, NAD+ decline, mitochondrial dysfunction, collagen loss, hormonal shifts. Peptides offer targeted interventions at specific nodes of that cascade. This collection walks you through the science at each node: what the research shows, what it doesn't, and where to go deeper.
One of the most studied anti-aging ingredients in skincare. GHK-Cu stimulates collagen, activates wound healing, and appears in over 400 peer-reviewed papers. This guide covers the science, the realistic results, and how to choose an effective product.
The hormonal shift of perimenopause and menopause creates specific vulnerabilities — bone density loss, sleep disruption, weight redistribution, vaginal atrophy. This guide examines which peptides have research support for each transition zone, and which are oversold.
Androgenetic alopecia, telogen effluvium, and peptide-mediated hair regrowth sit at an interesting intersection of endocrinology, dermatology, and emerging peptide science. This guide covers GHK-Cu, KPV, Thymosin alpha-1, and the evidence for each approach.
NAD+ is the linchpin of cellular energy metabolism — and it declines roughly 50% between your 20s and 60s. This guide examines NMN, NR, and the sirtuin pathway: what the research shows about repletion, what doses are used, and where the evidence gets thin.
Two of the most discussed modalities in regenerative and anti-aging medicine — often conflated, rarely compared rigorously. This guide breaks down the mechanisms of each, the overlap, the critical differences, and what the evidence base actually looks like for each.
Food as information — not just fuel. This guide examines the dietary patterns, specific compounds, and nutritional interventions that interface with peptide protocols and the longevity research: NAD+ precursors from food, sulforaphane, resveratrol, and the AMPK-activating eatables.
