Longevity: NAD+, Sermorelin & Healthy Aging Guides

Longevity is the most hyped corner of consumer health, and the gap between the marketing and the published research is wide. These guides cover what NAD+ does in the body and how injections, nasal spray, IV drips and oral precursors like NMN and NR compare on cost and evidence, how sermorelin works with your own growth hormone and what it costs, what human studies have and have not shown, which side effects to expect, and why where you buy matters.
