NAD+: cellular energy, DNA repair, and the longevity molecule — 2026 evidence-based guide
NAD+ declines roughly 50% between ages 40 and 60. Supplement companies want to sell you the solution. IV clinics want to drip it directly into your veins. Here is what the science actually supports — and where the hype outpaces the human data.
3-HAA: the longevity molecule your body already makes (and destroys too fast)
Every time you digest protein, your body briefly produces a molecule that extends lifespan in every species tested. Then it immediately breaks it down. What if you stopped breaking it down?

Kisspeptin-10: the master reproductive hormone regulator — 2026 evidence-based guide
Kisspeptin-10 sits at the very top of the reproductive hormone cascade — the upstream switch that tells your brain to produce GnRH, which triggers LH, FSH, and ultimately testosterone or estrogen. Its discovery in 2003 rewrote reproductive endocrinology. Here is the full clinical picture.

Semax is prescribed in Russia for stroke recovery, cognitive decline, and focus enhancement. It upregulates BDNF more reliably than any behavioral intervention short of exercise. Here is what 30 years of clinical use across Eastern Europe actually demonstrates.
Retatrutide: the triple-agonist weight loss molecule — 2026 evidence-based guide
Retatrutide (LY3437943) activates three receptors simultaneously — GLP-1, GIP, and glucagon — and produced the highest weight loss ever recorded in a Phase II obesity trial. It is not yet FDA-approved. Here is exactly where the science stands in April 2026.

Microdosing tirzepatide: why low-dose GLP-1 therapy may be the future of brain and metabolic health
You do not need to lose 40 pounds to benefit from a GLP-1. Research shows that small doses of tirzepatide — far below what is used for weight loss — can reduce inflammation, protect the brain, and improve heart and metabolic health, even if your weight is already normal. And you can now take it as a weekly injection, daily tablet, or daily sublingual drops.

The GLP-1 plateau: why the scale stalls and how to restart progress
Around month 4–6, most GLP-1 patients hit a plateau. The medication is still working — your body is recalibrating. Here is what is actually happening, how to tell a plateau from a stall, and the five evidence-based levers that restart loss without abandoning your protocol.
Food noise: how GLP-1 drugs actually rewire hunger
"Food noise" started as a patient phrase and became a research-grade concept in three years flat. Here is what it really is, how semaglutide and tirzepatide silence it, and what happens when you stop the medication.
