Common questions.

How often is NAD+ injected?
2x weekly subcutaneous, dose titrated to tolerance. Most men notice cleaner energy and mental clarity inside 3 to 4 weeks. NAD+ declines by roughly 50% from your 20s to your 50s, which is why supplementation is the centerpiece of the longevity stack.
Why Metformin if I'm not diabetic?
Off-label longevity use. The published TAME and MILES trials suggest Metformin improves insulin sensitivity, slows mitochondrial decline, and may extend healthspan. Dose is 500 mg to 1000 mg daily, titrated by your practitioner.
What is Low-dose Naltrexone for?
LDN at 4.5 mg nightly has emerging data for inflammation, sleep quality, and recovery. It is off-label and dispensed only when your practitioner determines it is clinically appropriate.
Can I stack longevity protocols with TRT?
Yes. The full-stack member typically runs TRT or Enclomiphene, plus a GLP-1 if weight is in play, plus NAD+ and Metformin for cellular repair. Your practitioner reviews the entire stack.
